WebP to PNG Converter

WEBP TO PNG converts a .webp image (almost always saved from a website or Google Images) into a PNG that opens everywhere, and it does this entirely on your device with no upload. The usual trigger is a downstream app that flatly refuses WebP: Microsoft Paint, Office 2019 and earlier, Outlook desktop, older Photoshop, a print shop, or a CMS uploader like Wix or older WordPress. You want a universally-openable file with the transparent background intact, fast, free, and without handing a personal or work image to a random conversion server.

What this conversion actually does (and does NOT do)

PNG encoding is always lossless, so the conversion step itself never adds artifacts or banding. PNG carries up to 24-bit truecolor plus 8-bit alpha, which matches WebP's color depth, so switching containers introduces no color shift on its own. The honest catch: this conversion changes the container, it does not recover quality. If your source was a lossy WebP, the compression artifacts WebP already discarded are baked into the pixels, and PNG faithfully preserves them rather than restoring lost detail.

Expect the file to get bigger, not smaller, and that is normal. Lossless WebP is typically 25-30% smaller than the equivalent PNG, and lossy WebP with transparency can be roughly 3x smaller than PNG, so a 300 KB WebP can easily become a 1 MB or larger PNG. That size increase is expected, not a bug. Transparency, on the other hand, is preserved exactly: both formats support 8-bit alpha, so a cut-out background carries over with no re-masking. One real gotcha to watch for is animation. An animated WebP holds multiple frames, and a plain static-PNG converter silently collapses it to a single frame; animated WebP should go to APNG (Animated PNG) to keep every frame and its timing.

When to choose WEBP to PNG vs the alternative

Choose WebP to PNG specifically when a target tool rejects WebP or when you need the transparent background to survive: Office 2019 and earlier, Outlook desktop, older Photoshop, print workflows, and some CMS uploaders. If the image is staying on the web (a site asset, an email banner with no transparency), keeping WebP, or converting to a smaller flat format, usually wins on size. When your image has no alpha channel and you mainly care about a small file for upload or email, converting WebP to JPG (JPEG) produces a far lighter file than PNG, at the cost of dropping any transparency. Reach for PNG when the alpha channel matters; reach for JPG when it does not.

How to convert

1. Drop one or many .webp files into the tool — they are read locally in the page, never uploaded.
2. The output format is pre-selected to PNG; because PNG is lossless there is no quality slider to set for this target.
3. Transparency is preserved automatically — no background-color picker needed, the alpha channel maps straight across.
4. Click Convert. A single file downloads directly; multiple files download as a ZIP, with no file-count cap.

No upload. It runs on your device.

The conversion runs inside your browser tab via Rust compiled to WebAssembly. Your file is read into memory and processed locally, with zero network requests for the image itself, so nothing is uploaded, stored, or logged. After the page loads once, it keeps working offline, and there is nothing to delete afterward because nothing ever left your machine. You can verify this yourself: open your browser's DevTools, watch the Network tab, and confirm no request carries your file out. This matters because WebP files saved from work or personal browsing often include screenshots of internal dashboards, signatures, ID or medical scans, and other confidential images you should not be dropping onto a third-party server.

No limits

Unlimited batch conversion, no file-size limit, no file-count cap, no watermark on the output, no sign-up, and no ads. Convert one WebP or a few hundred in the same pass.

Frequently asked questions

Does converting WebP to PNG lose quality?

No, the conversion itself is lossless because PNG encoding never discards data, so it adds no new artifacts or banding. However, if the source WebP was a lossy file, any compression artifacts already in it are preserved faithfully in the PNG rather than removed.

Will the transparent background be preserved when I convert WebP to PNG?

Yes. Both WebP and PNG support 8-bit alpha transparency, so a transparent or cut-out background carries over exactly with no manual masking. The alpha channel maps straight across, which is the main reason to pick PNG over a flat format like JPG.

Why is my PNG file larger than the original WebP?

This is expected, not a defect. Lossless WebP is usually 25-30% smaller than PNG, and lossy WebP with transparency can be about 3x smaller, so a 300 KB WebP can become a 1 MB or larger PNG simply because PNG stores the same pixels less compactly.

Is this WebP to PNG converter free and is there a file-size limit?

It is completely free with no sign-up, no watermark, and no ads. There is no file-size limit and no file-count cap because the work runs locally in your browser instead of on a metered server with free-tier quotas.

Do my files get uploaded to a server, or is the conversion done in my browser?

Everything runs in your browser tab via Rust/WebAssembly, with zero network requests for the image, so your file never leaves your device. You can confirm this by watching the Network tab in your browser's DevTools while you convert.

Can I convert multiple WebP files to PNG at once (batch)?

Yes, drop as many .webp files as you like in a single pass. A single file downloads directly, and multiple files download together as a ZIP archive, with no cap on how many you can process.

How do I convert an animated WebP to PNG?

An animated WebP should be converted to APNG (Animated PNG) to keep all of its frames and their timing. A plain static-PNG conversion silently drops everything except the first frame, so check whether your source is animated before converting.

Why won't my computer open a WebP file?

WebP is a relatively modern web format that many desktop apps never added support for, including Office 2019 and earlier, Outlook desktop, older Photoshop, and Microsoft Paint on older systems. Converting to PNG produces a universally-openable file those tools accept without complaint.

Can I convert WebP to PNG offline / without internet?

Yes. Once the page has loaded, the WebAssembly converter runs entirely on your device, so it keeps working with no connection. No file is sent anywhere, which is also why there is nothing to delete afterward.

Does converting a lossy WebP to PNG make it sharper?

No. Converting a small lossy WebP to PNG only changes the container and inflates the file size; it cannot restore detail the WebP already threw away. The right reason to convert is compatibility, not quality recovery.
