Best PNG Image Converter (2026): 10 Tools Ranked

PNG is everywhere — screenshots, logos, transparent graphics, exported designs — but it's rarely the format you actually want to keep. You end up needing to convert PNG to JPG to shrink a photo, to WebP or AVIF to speed up a website, to ICO to make a favicon, or to PDF to hand off a document. The right converter does all of that (and back again) without wrecking quality or your privacy.

Quick answer: For all-round PNG conversion, the best free tool is XnConvert, a desktop app that batch-converts PNG to and from 80+ output formats entirely offline. If you'd rather not install anything, Pixelor is the best browser pick — it converts your PNGs on your own device without uploading them. Below we rank ten genuinely good options, each scored on five weighted criteria and verified against its official site in 2026.

Disclosure: Pixelor publishes this list and is one of the tools featured in it. We rank it #2, not #1, and we say plainly where a competitor beats it — that's the only way a roundup like this earns your trust.

Key Takeaways

• Best overall (free desktop batch): XnConvert — 500+ inputs, 80+ outputs, presets, fully offline.
• Best no-install / most private: Pixelor — converts PNG in your browser, nothing uploaded.
• Best free Windows utility: IrfanView — fast, tiny, batch conversion with plugins.
• Best full editor: GIMP and Photopea — export PNG to any format with pixel-level control.
• Best for developers / APIs: CloudConvert — 200+ formats behind a mature REST API.

How we evaluated & scored these tools

Every converter is scored on five weighted criteria, each out of 10, rolled into a weighted overall score out of 10:

Overall = 0.30·Quality + 0.20·Batch + 0.20·Privacy + 0.15·Ease + 0.15·Price. Scores reflect each tool's real, verified capabilities. Prices and limits change, so treat the numbers as a starting point and confirm on the vendor's page before you rely on them.

Comparison table: 10 best PNG converters

"Uploads files?" is a privacy signal: a "No" means your PNGs never leave your device. "Bulk?" varies a lot — some tools give batch away free, others gate it behind a paid tier, which we call out per entry.

1. XnConvert — best free offline batch converter

Best for: anyone converting a folder of PNGs for free without uploading anything. XnConvert is a cross-platform desktop app (Windows, Mac, Linux) that reads 500+ formats and writes to around 80, including JPG, WebP, AVIF, HEIC, PDF, and TIFF, with 80+ optional actions like resize and color adjustments (XnView).

Quality 9 · Batch 10 · Privacy 9 · Ease 7 · Price 10 → 9.1/10

Pros: genuinely free, huge format coverage, saveable presets, watch-folder automation, everything runs offline. Cons: requires a download; the action-heavy interface is busier than a one-click web tool.

Price: Free (check the vendor page for commercial licensing). Who should pick it: desktop users who batch-convert PNGs often and want maximum control at no cost.

2. Pixelor — best no-install and most private converter

Best for: converting PNG to JPG, WebP, AVIF, or ICO fast, free, and privately without installing software. Pixelor runs entirely client-side — the conversion happens inside your browser tab, so your images are never uploaded to a remote server. That makes it a strong pick for logos, screenshots, and personal graphics you'd rather not send anywhere.

Quality 8 · Batch 7 · Privacy 10 · Ease 9 · Price 8 → 8.4/10

Pros: 100% client-side and private, nothing to install, works on any OS with a browser, free for everyday use. Cons: the largest batches and biggest files need a credit pack; very old browsers may lack the codecs it relies on.

Price: Free for everyday use; credit packs from $4.99 unlock bulk & larger files. The free tier converts up to 5 files at once with no account; bulk conversion of up to 100 images (or 50 videos) and larger files runs on credit packs — Starter 50/$4.99, Plus 200/$14.99, Pro 500/$29.99, Business 1,500/$69.99. Who should pick it: most people, especially anyone converting personal PNGs who doesn't want them uploaded. Convert PNG to JPG

3. IrfanView — best fast Windows utility

Best for: Windows users who want a tiny, fast tool that batch-converts PNGs. IrfanView is a long-trusted image viewer with a powerful Batch Conversion/Rename dialog and support for 130+ formats via optional plugins (IrfanView).

Quality 8 · Batch 9 · Privacy 9 · Ease 5 · Price 9 → 8.1/10

Pros: free for personal use, extremely fast and lightweight, robust batch engine, keeps files on your machine. Cons: Windows-only; the dated modal UI has a learning curve; some formats need the separate plugin pack; commercial use requires a license.

Price: Free for personal use. Who should pick it: Windows users who value speed and a proven batch workflow over a modern interface.

4. GIMP — best full-control desktop editor

Best for: people who want to edit and convert in one place. GIMP is a free, open-source image editor for Windows, Mac, and Linux; you open a PNG and use File > Export As to save it as JPG, WebP, TIFF, or more, with full control over compression and transparency (GIMP).

Quality 9 · Batch 5 · Privacy 9 · Ease 5 · Price 10 → 7.8/10

Pros: completely free and open source, professional-grade export options, fully offline, no account. Cons: batch conversion needs the BIMP plugin or Script-Fu; the interface is overkill if you only want to convert; steeper learning curve than a dedicated tool.

Price: Free. Who should pick it: users who also want to edit their PNGs and don't mind a heavier tool.

5. Photopea — best browser-based editor

Best for: Photoshop-style editing plus PNG export without installing anything. Photopea runs in your browser and, notably, processes files locally on your device rather than uploading them; export to PNG, JPG, WebP, SVG, PDF, or GIF from the File > Export as menu (Photopea).

Quality 9 · Batch 4 · Privacy 9 · Ease 7 · Price 9 → 7.7/10

Pros: powerful editor in a browser tab, files stay on your device, opens PSDs, free with ads. Cons: built for editing one file at a time, so it's not a true batch converter; the full editor is more than a quick conversion needs.

Price: Free (ad-supported); a paid tier removes ads — see vendor page (as of 30 Jul 2026). Who should pick it: designers who want to tweak a PNG and export it in another format in the same window.

6. CloudConvert — best for developers and APIs

Best for: developers who need conversion as a service. CloudConvert is a mature converter supporting 200+ formats, and its real strength is a well-documented REST API you can wire into your own apps (CloudConvert).

Quality 9 · Batch 8 · Privacy 3 · Ease 8 · Price 5 → 6.9/10

Pros: excellent API, huge format coverage, fine control over quality and metadata, reliable at scale. Cons: files are uploaded to CloudConvert's servers; the free tier is limited (the pricing page lists around 10 free conversions per day, as of 30 Jul 2026), so volume use requires paying.

Price: Free tier (~10 conversions/day); beyond that, pay-as-you-go credit packages from ~$9 (500 conversion minutes) or subscriptions from ~$8/month (1,000 minutes) — roughly $8–$9 to start (as of 30 Jul 2026; confirm on the pricing page). Who should pick it: teams automating PNG conversion programmatically.

7. Convertio — best broad-format online converter

Best for: one-off online conversions across many formats. Convertio is a polished web converter that handles PNG to and from a long list of image, document, and archive formats (Convertio).

Quality 8 · Batch 7 · Privacy 3 · Ease 8 · Price 5 → 6.4/10

Pros: very wide format support, clean interface, no install. Cons: files are uploaded to Convertio's servers; the free tier is capped by a per-file size limit and a daily conversion allowance, so heavier use needs a paid plan.

Price: Freemium — free tier of ~25 conversions/24h; paid plans roughly $9.99–$25.99/month (Light $9.99, Basic $14.99, Unlimited $25.99) (as of 30 Jul 2026; confirm on the vendor page). Who should pick it: anyone who occasionally needs an obscure format and is fine with a server-side upload.

8. iLoveIMG — best web image toolkit

Best for: PNG conversion alongside a whole suite of web image tools. iLoveIMG pairs its PNG to JPG converter with resize, crop, and compress tools in one place.

Quality 7 · Batch 6 · Privacy 3 · Ease 9 · Price 6 → 6.2/10

Pros: convenient all-in-one toolkit, very easy to use, supports batch, widely trusted; the site states uploaded files are deleted after a set time. Cons: files are uploaded to iLoveIMG's servers; free-tier limits and higher batch caps sit behind a paid plan.

Price: Free tier with limits; paid Premium — see vendor page (as of 30 Jul 2026). Who should pick it: users who already use iLoveIMG for other edits and want conversion in the same familiar place.

9. Adobe Express — best quick web quick-action

Best for: a fast, free one-off conversion inside Adobe's ecosystem. Adobe Express offers a simple Convert to JPG quick action for PNGs, aimed at social and web graphics (Adobe Express).

Quality 8 · Batch 5 · Privacy 3 · Ease 8 · Price 6 → 6.1/10

Pros: trusted brand, clean quick-action flow, free plan available, tidy output. Cons: files are uploaded to Adobe's servers; the quick action is single-file focused; you may be nudged toward an Adobe account or paid plan for more.

Price: Free plan; paid plans — see vendor page (as of 30 Jul 2026). Who should pick it: people already in the Adobe ecosystem who want a quick, one-off conversion.

10. FreeConvert — best for large single files online

Best for: converting a big PNG (or a few) in the browser. FreeConvert's PNG converter is notable for a generous free per-file size ceiling — its pages advertise up to 1 GB (as of 30 Jul 2026).

Quality 7 · Batch 5 · Privacy 3 · Ease 8 · Price 6 → 5.8/10

Pros: high free file-size limit, broad format support, no install. Cons: files are uploaded to FreeConvert's servers; the free plan limits concurrency and daily conversion time, so true bulk needs a subscription.

Price: Free with limits; paid plans — see vendor page (as of 30 Jul 2026). Who should pick it: anyone converting occasional large PNGs online who's comfortable with a server-side upload.

How to pick the right PNG converter

Match the tool to the job rather than chasing one winner:

• Converting personal or sensitive graphics? Use a tool that doesn't upload your files — Pixelor (browser), XnConvert or IrfanView (desktop), or GIMP/Photopea (editors). Server-based tools like CloudConvert, Convertio, iLoveIMG, Adobe Express, and FreeConvert send your images to a remote server, which is fine for non-sensitive files but worth knowing.
• Batch-converting lots of PNGs? XnConvert (free desktop) and IrfanView (Windows) are the cleanest free paths; in the browser, Pixelor does up to 100 at once with a credit pack.
• Making a favicon? You want ICO output — see PNG to ICO.
• Optimizing a website? Convert to modern formats with PNG to WebP; WebP and AVIF are far smaller than PNG for photographic content (MDN).
• Building software? CloudConvert's API is the right tool.

One practical note: PNG is lossless, so converting to a lossy format like JPG or WebP trades a little fidelity for a much smaller file — usually invisible at high quality, and worth it for photos. Keep PNG when you need sharp text or transparency. Convert PNG to WebP

Frequently asked questions

What is the best free PNG converter?

For offline batch work, the best free PNG converter is XnConvert, which converts folders of PNGs to 80+ formats without uploading them. If you'd rather not install anything, Pixelor converts PNGs in your browser for free, and IrfanView is a fast free option on Windows.

How do I convert PNG to JPG without losing quality?

Convert at a high quality setting (90 or above) using any tool that lets you control JPG quality — XnConvert, GIMP, Photopea, or Pixelor's PNG to JPG tool. Because JPG is lossy, it can't be truly lossless, but at high quality the difference is invisible; the trade-off is that JPG drops PNG's transparency, filling it with a background color.

Can I convert PNG to WebP or AVIF?

Yes. WebP and AVIF are modern web formats that are much smaller than PNG for most images. XnConvert, GIMP, Photopea, and CloudConvert all export them, and you can convert PNG to WebP directly in your browser with Pixelor.

Is it safe to convert PNG files online?

It depends on the tool. Many online converters upload your images to a remote server to process them. A client-side converter processes files entirely in your browser so nothing is uploaded — the safest choice for personal or sensitive graphics. Pixelor and Photopea both work this way; see our Privacy page for how we handle files.

How do I turn a PNG into a favicon?

Convert it to the ICO format, which browsers use for favicons. Pixelor's PNG to ICO converter writes a single-resolution ICO from a square source image, which is all most sites need; if you want one .ico packing several sizes (16/32/48px), reach for a dedicated favicon tool or ImageMagick's -define icon:auto-resize. Then reference the .ico file in your site's HTML.
