WEBP to PNG Converter
Convert a WebP image to a lossless PNG right in your browser — transparency preserved, no upload, no watermark.
Short answer
To convert WebP to PNG, drop your .webp file below and download the PNG. It runs in your browser — nothing is uploaded. PNG is supported everywhere (older software, email, editors) where WebP sometimes isn’t, and transparency is preserved.
Why convert WebP to PNG?
WebP gives smaller files, but some older apps, editors, and email clients still can’t open it. PNG is universally supported and lossless, so converting is the quickest fix when a program refuses your .webp. Both formats support transparency, so an alpha channel is carried across intact.
Does it keep transparency?
Yes. PNG has a full alpha channel, so any transparent regions in your WebP stay transparent — no white background is added. That makes this the right choice for logos, stickers, and UI assets you’ll place over other content.
Image formats compared
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| JPG / JPEG | Lossy | No | Photographs |
| PNG | Lossless | Yes | Logos, screenshots, line art |
| WebP | Either | Yes | Web images — smallest at equal quality |
| GIF | Lossless | 1-bit only | Short animations |
| HEIC | Lossy | Yes | iPhone photos — small, poorly supported |
| SVG | Vector | Yes | Icons and logos at any size |
| TIFF | Either | Yes | Scans and print masters |
| ICO | Lossless | Yes | Website favicons |
The one rule that matters: converting a lossy image (JPG, HEIC) to a lossless one (PNG) cannot recover detail already thrown away — it just makes a bigger file. Going the other way, PNG → JPG, is where the real savings are, and photographs lose nothing you can see.
How we calculate this
Conversion happens locally in your browser — here is exactly how:
- Decode. your WebP is decoded to a bitmap in the browser (via createImageBitmap) — never uploaded to any server.
- Draw. the bitmap is drawn to an HTML canvas at its original dimensions, keeping the alpha channel.
- Encode. the canvas is exported with canvas.toBlob('image/png'), producing a lossless, universally-supported PNG.
Assumptions
- Everything runs client-side; large images are limited only by your device's memory.
- PNG is lossless, so files are typically larger than the source WebP.
- Transparency is preserved end to end.

Frequently asked questions
How do I convert WebP to PNG?+
Drop your .webp file into the box above and download the PNG the tool produces. The whole conversion runs in your browser, so the image is never uploaded, and it works offline once the page has loaded.
Why won't my WebP open in some programs?+
WebP is newer than PNG/JPG, so some older editors, email clients, and operating-system tools don't yet decode it. Converting to PNG gives you a file that opens everywhere without losing quality.
Is the conversion lossless?+
The PNG output is lossless. If your source WebP used lossy compression, those pixels are already baked in — converting to PNG won't restore lost detail, but it won't discard any more, either.
Does transparency survive?+
Yes. Both WebP and PNG support an alpha channel, so transparent areas remain transparent in the PNG. No solid background is added.
Are my images uploaded?+
No. Everything runs 100% in your browser using the HTML canvas, so your WebP never leaves your device. Nothing is stored or sent to any server.
Will the PNG be bigger than the WebP?+
Usually, yes. WebP is designed for small files, while PNG is lossless and uncompressed by comparison, so expect a larger PNG. If size matters more than universal support, convert to JPG instead.
