Best PNG to PDF Converter (2026): 10 Tools Ranked

Most people searching for a PNG to PDF converter want the same thing: take a folder of screenshots, scans or design exports and turn them into one tidy PDF they can email, print or archive. Tools differ enormously on exactly that — some merge everything into a single ordered document, some hand you a separate PDF per image, and some cap the free tier at a handful of files. This guide covers both directions: PNG to PDF, and PDF back to PNG (there's a dedicated section for the reverse below, because the winners aren't identical).

Quick answer: For most people the best PNG to PDF converter is iLovePDF — its Image to PDF tool merges many PNGs into one PDF with a single checkbox, free, with page size, orientation and margin controls. If you'd rather your files never leave your device, Pixelor converts entirely in your browser with nothing uploaded. For unlimited free use in both directions, PDF24 is the pick. Everything below was verified against each vendor's own site in 2026.

Disclosure: Pixelor publishes this list and is one of the tools featured in it. We rank Pixelor #4 on purpose — dedicated PDF suites legitimately lead this category, because they merge many images into one document and we currently don't. We'd rather tell you that than pretend otherwise.

Key Takeaways

• Best overall: iLovePDF — free, merges up to ~20 PNGs into one PDF, real page controls.
• Best polished experience: Smallpdf — cleanest interface, combines images, hourly/daily free caps.
• Best truly free (both directions): PDF24 — unlimited, no watermark, plus an offline Windows Creator.
• Best for privacy: Pixelor — converts in your browser, nothing is ever uploaded.
• Best for developers: CloudConvert — a solid PNG↔PDF API, though the free tier is now small.

How we evaluated and scored these tools

Every roundup we publish uses the same five weighted criteria, each scored out of 10 and rolled into a weighted overall. That keeps rankings comparable between articles and defensible from each tool's real, verified capabilities.

Overall = 0.30·Quality + 0.20·Batch + 0.20·Privacy + 0.15·Ease + 0.15·Price. Prices and limits move often, so treat every figure as a starting point and confirm on the vendor's page.

Comparison table: 10 best PNG to PDF converters

Two notes on the table. "Uploads files?" is the privacy signal — a "No" means your images never leave your device. And the bulk column deliberately separates two different things: converting many PNGs at once, and merging them into a single PDF. Almost every tool here does both; Pixelor is the honest exception on the second.

1. iLovePDF — best PNG to PDF converter overall

Best for: turning a pile of PNGs into one clean PDF, free. iLovePDF's Image to PDF tool accepts PNG alongside JPG, BMP, GIF and TIFF, and offers a "Merge all images in one PDF file" checkbox plus page orientation, page size (Fit / A4 / US Letter) and margin settings (iLovePDF).

Scores: Quality 9 · Batch 9 · Privacy 5 · Ease 10 · Price 8 → 8.2/10

Pros: merges many images in one click, drag-to-reorder before converting, genuine page controls, part of a full PDF suite with desktop and mobile apps. Cons: files are uploaded to iLovePDF's servers; the free tier caps a task at roughly 20 images / 40 MB; its reverse tool outputs JPG rather than PNG.

Price: Free for everyday use (as of 30 Jul 2026); Premium roughly $4–$7/month (as of 30 Jul 2026). Who should pick it: most people combining a set of screenshots or scans into a single document.

2. Smallpdf — best polished experience

Best for: people who want the smoothest interface. Smallpdf's PNG to PDF tool lets you add more images after the first — PNG, GIF or TIFF — combine them into a single PDF, and set page size, orientation and margins; files are deleted after an hour (Smallpdf).

Scores: Quality 9 · Batch 8 · Privacy 5 · Ease 10 · Price 7 → 7.9/10

Pros: excellent UX with no signup to start, combines multiple PNGs, mature toolkit, one-hour file deletion, ISO 27001 certified. Cons: files are uploaded; the free tier is metered by tasks, so daily users are pushed toward Pro.

Price: Free with task caps (as of 30 Jul 2026); Pro roughly $10–$15/month (as of 30 Jul 2026). Who should pick it: occasional converters who value polish, and teams already on Smallpdf.

3. PDF24 — best truly free option, in both directions

Best for: unlimited conversion at zero cost. PDF24 runs dedicated PNG to PDF and PDF to PNG tools, both free with no limits, no watermark and no registration; you can drag many images into order and combine them, and files are deleted from its German servers after an hour. The free PDF24 Creator desktop app for Windows works offline.

Scores: Quality 8 · Batch 9 · Privacy 6 · Ease 7 · Price 9 → 7.8/10

Pros: genuinely unlimited and free, no watermark, dedicated tools for each direction, offline Creator keeps files on your PC. Cons: the web version still uploads (ad-supported, more utilitarian interface); the offline Creator is Windows-only.

Price: Free (as of 30 Jul 2026). Who should pick it: anyone converting a lot, especially Windows users who will install the offline Creator.

4. Pixelor — best for privacy

Best for: converting PNGs that shouldn't be uploaded anywhere — ID scans, payslips, contracts, internal screenshots. Pixelor runs entirely client-side: conversion happens inside your browser tab, so nothing is sent to or stored on a remote server. It works in reverse too, rendering a PDF page to PNG locally with PDF.js.

Scores: Quality 6 · Batch 6 · Privacy 10 · Ease 9 · Price 7 → 7.4/10

Pros: the only tool here that never uploads your file, no account or install, free for everyday use, works offline once loaded, doubles as a wider image and video converter. Cons: Pixelor converts each PNG into its own PDF rather than merging a set into one document, so for a single combined PDF you want iLovePDF, PDF24 or Smallpdf. On the reverse trip it renders the first page of a PDF, and larger batches need a credit pack.

Price: Free for everyday use — up to 5 files at once, no account (25 MB per image); credit packs from $4.99 unlock batches of up to 100 images and larger files (Starter 50/$4.99, Plus 200/$14.99, Pro 500/$29.99, Business 1,500/$69.99). It's a credit model, not a subscription. Who should pick it: anyone converting private or sensitive PNGs, or working on a locked-down machine. Convert PNG to PDF in your browser

5. Adobe Acrobat — best for fidelity and trust

Best for: output that has to be exactly right. Adobe's free online converter turns a PNG into a high-quality PDF with no watermark and no registration for the basic job, and there's a matching PDF to PNG tool (Adobe).

Scores: Quality 9 · Batch 5 · Privacy 5 · Ease 9 · Price 6 → 7.0/10

Pros: reference-grade rendering from the company that created PDF, no size limit on the basic online tool, deep editing and OCR in Pro. Cons: the free flow is built around one file at a time — combining many PNGs means the Merge tool and, in practice, an Acrobat subscription; you may need to sign in, and files are uploaded.

Price: Free for basic online conversion (as of 30 Jul 2026); Acrobat Pro roughly $19.99–$29.99/month (as of 30 Jul 2026). Who should pick it: Adobe users and anyone who needs pixel-accurate, print-ready output.

6. Sejda — best for page-size control

Best for: deciding exactly how each image sits on the page. Sejda's images-to-PDF tool takes PNG, JPG, WEBP and GIF, merges them into one document in your chosen order, and lets you pick A4 or fit-to-image page sizing; its PDF to image tool exports PNG or TIFF as well as JPG (Sejda).

Scores: Quality 8 · Batch 7 · Privacy 5 · Ease 8 · Price 5 → 6.8/10

Pros: handles both directions with real options, clean interface, files auto-deleted after a couple of hours, desktop app available. Cons: the free tier is tight — around 3 tasks per hour with page and size caps — so any volume needs a pass; the web version uploads.

Price: Free within limits (as of 30 Jul 2026); Week Pass ~$5 or monthly around $7.50 (as of 30 Jul 2026). Who should pick it: users who care about page layout and only convert now and then.

7. CloudConvert — best for developers and APIs

Best for: wiring PNG↔PDF conversion into your own software. CloudConvert exposes a well-documented REST API alongside its web tools, with control over page size, DPI and merging (CloudConvert).

Scores: Quality 9 · Batch 8 · Privacy 4 · Ease 6 · Price 4 → 6.6/10

Pros: excellent API, 200+ formats, precise conversion parameters, reliable at scale, unlimited file sizes on paid tiers. Cons: files are uploaded; the free allowance is now small — around 10 conversions per day — so any real use is paid; the web UI holds your hand less than its rivals.

Price: Free tier around 10 conversions/day (as of 30 Jul 2026); prepaid credit packages and subscriptions priced by volume — see vendor page (as of 30 Jul 2026). Who should pick it: developers automating conversion, not one-off users.

8. Xodo — best for a quick web merge

Best for: a fast, no-signup combine. Xodo's PNG to PDF tool lets you choose whether to merge your images into one file or convert each separately, and it sits alongside 30+ other document tools including PDF to PNG (Xodo).

Scores: Quality 7 · Batch 7 · Privacy 5 · Ease 8 · Price 5 → 6.5/10

Pros: merge-or-separate choice up front, works on web, extension and mobile apps, AES-256 at rest and TLS in transit, covers both directions. Cons: files are uploaded; fewer layout controls than iLovePDF or Sejda; higher limits and advanced features sit behind a paid tier.

Price: Free for basic conversion, with a paid Pro tier — see vendor page (as of 30 Jul 2026). Who should pick it: anyone wanting one quick merge without creating an account.

9. Convertio — best for format breadth

Best for: people who convert lots of different file types and want one place to do it. Convertio combines multiple PNGs into a single multi-page PDF and supports 300+ formats overall, including PDF back to PNG (Convertio).

Scores: Quality 7 · Batch 7 · Privacy 4 · Ease 8 · Price 5 → 6.3/10

Pros: enormous format coverage, simple browser flow, merges in your chosen order, cloud-storage imports. Cons: files are uploaded; the free tier is capped (roughly 100 MB per file, 2 concurrent conversions and about 10 conversion minutes per 24 hours), so regular use means paying.

Price: Free with caps (as of 30 Jul 2026); paid plans roughly $11.99–$44.99/month, less on annual billing (as of 30 Jul 2026). Who should pick it: occasional users who also convert video, audio and documents.

10. FreeConvert — best for large PNG files

Best for: big or very high-resolution images. FreeConvert lets you adjust page size, orientation and margin and combine multiple PNGs into one PDF, with a free file ceiling of about 1 GB (FreeConvert).

Scores: Quality 7 · Batch 6 · Privacy 4 · Ease 8 · Price 5 → 6.1/10

Pros: unusually high free size limit, real layout options, no account needed for web use, handles PDF to PNG too. Cons: files are uploaded; the free plan is metered at roughly 20 conversion minutes per day (max 5 minutes per file), so bulk work needs a subscription.

Price: Free with daily minute limits (as of 30 Jul 2026); paid plans from about $12.99/month up to $29.99/month (as of 30 Jul 2026). Who should pick it: anyone converting a handful of very large PNGs online.

Also considered: Zamzar handles PNG to PDF and back with a huge format library, but its free tier is the tightest here — around 2 files per 24 hours and a very small free file-size cap — so it didn't make the ten.

Converting the other way: the best PDF to PNG converters

Going PDF → PNG is a different job. PNG is lossless, so text and line art stay crisp but files get big — and what separates tools here is whether they export every page and let you set the DPI.

• Best overall for PDF to PNG: PDF24 — a dedicated, unlimited, free PDF to PNG tool that renders pages to lossless PNG with no watermark.
• Best quality: Adobe Acrobat — Acrobat's PDF to PNG tool preserves text, graphics and formatting faithfully.
• Best for control: Sejda and CloudConvert — both let you choose resolution/DPI and page ranges rather than accepting a default.
• Best for a whole batch of documents: Smallpdf — upload several PDFs and convert them to PNG in one pass.
• Best for privacy: Pixelor — renders the PDF page to PNG in your own browser, so a confidential document is never uploaded. It converts the first page, which is ideal for single-page files, invoices and covers; for a 40-page report, use one of the PDF suites above. Convert PDF to PNG privately

One caveat worth knowing: iLovePDF's reverse tool outputs JPG, not PNG, so it wins the PNG → PDF direction but isn't the pick for the return trip.

How to pick the right PNG to PDF converter

• Combining many PNGs into one document? iLovePDF, PDF24, Smallpdf, Sejda, Xodo, Convertio and FreeConvert all merge; iLovePDF and PDF24 do it free with the fewest strings.
• Converting sensitive images? Use a tool that doesn't upload — Pixelor in the browser, or PDF24 Creator offline on Windows.
• Need print-accurate output? Adobe Acrobat, then Sejda for page-size control.
• Automating it? CloudConvert's API, priced by credits.
• Huge files? FreeConvert's ~1 GB free ceiling.

A practical tip: PNG is lossless, so a PDF built from PNG screenshots can be surprisingly large. If size matters, run the images through an image compressor first, or convert photographic PNGs to JPG before assembling the PDF.

Frequently asked questions

What is the best free PNG to PDF converter?

For merging several PNGs into one PDF, iLovePDF and PDF24 are the strongest free options — no watermark, real page controls, and PDF24 has no usage limits at all. If you'd rather not upload the files, Pixelor converts free in your browser.

How do I combine multiple PNG images into one PDF?

Drop all your images into a tool that supports merging, drag them into the order you want, tick the "merge into one PDF" option, choose a page size, and convert. iLovePDF, Smallpdf, PDF24, Sejda, Xodo, Convertio and FreeConvert all offer this. Pixelor currently produces one PDF per image, so it isn't the right tool for a single combined document.

Does converting PNG to PDF reduce image quality?

Generally no — a PDF wraps your image rather than re-encoding it aggressively. Quality loss creeps in when a converter re-compresses images as JPEG inside the PDF or downsamples them to keep the file small, so choose a tool that exposes a quality or page-size setting if fidelity matters.

Is it safe to convert PNG to PDF online?

It depends on the tool. Most online converters upload your images, process them on a server and delete them later (Smallpdf and PDF24 state one hour; Sejda states a couple of hours). That's fine for non-sensitive files. For IDs, contracts or medical scans, a client-side converter processes everything in your browser so nothing is uploaded at all — see our Privacy page for how Pixelor handles this.

PNG or JPG inside a PDF — which should I use?

PNG for screenshots, logos, diagrams and anything with text or sharp edges, because it's lossless. JPG for photographs, where the file will be several times smaller with no visible difference. Mixed set? Convert the photos to JPG first, then build one PDF from everything.

About this list — how we test. This roundup was researched and written by Team Pixelor. We verified each tool's merge behaviour, both conversion directions, limits and pricing against its official website in 2026, and we hedge anything we couldn't confirm — always check the vendor's page before relying on a number. Pixelor is a free, client-side file converter: your files are processed in your browser and never uploaded, and, as disclosed above, it's one of the ten tools featured here, ranked #4 because dedicated PDF suites merge multiple images into a single document and we don't.
