Transparency Kept Never Saved to Disk

WebP to PNG Converter

Turn .webp logos, stickers, icons and cut-outs into PNGs with the transparent background intact, pixel for pixel. No signup, nothing to install.

How to convert WebP to PNG

  1. 1

    Drop your .webp files in the box above, or click browse. Up to 3 files per batch with no signup or on a free account, and 25 per batch on a Day Pass or any paid plan. A whole folder to convert? A $2 Day Pass covers 100 uploads in 24 hours, no account needed.

  2. 2

    Convert. There is nothing to set: each file becomes a pixel-exact PNG with its transparency kept. A Strip EXIF switch appears once your files are in if you want to keep embedded metadata.

  3. 3

    Download your PNGs. More than one file comes back as a single zip, ready for Canva, Photoshop, Figma, slides or any upload form.

When PNG is the right choice

Pick PNG when the image has a transparent background, sharp edges or text: logos, icons, stickers, product cut-outs, screenshots and graphics you will keep editing. PNG keeps every pixel and the alpha channel, and every design tool, office app and upload form accepts it.

For an ordinary photo with no transparency, WebP to JPG is usually the better trade: it opens just as widely in a much smaller file.

Need a smaller PNG?

In the Mochify web app you can type "convert to PNG and compress" to get a reduced-palette PNG, typically 4 to 5 times smaller, or "PNG under 500kb" to set a size limit. Both keep transparency. Graphics compress very well this way; photos can show banding, so keep those as JPG.

Frequently asked questions

Is this WebP to PNG converter free?
Yes. Convert up to 3 files at a time with no signup, or 25 a month with a free account, at up to 20MB per file. For a bigger folder, a $2 Day Pass covers 100 uploads in 24 hours with no account, and Seller and Pro plans convert 25 files per batch.

Does the PNG keep transparency?
Yes. The alpha channel is carried through, so transparent backgrounds and soft edges come back exactly as they were in the WebP.

Is the conversion lossless?
Yes. The PNG reproduces the pixels of the WebP exactly; nothing is compressed away in the conversion. It cannot restore detail a lossy WebP already discarded, so the PNG looks exactly like the WebP, no better and no worse.

Why is the PNG bigger than the WebP?
Because PNG stores every pixel exactly, while most WebPs are lossy and much more compact. A PNG several times the size of the WebP is normal, especially for photos. If you only need a photo to open everywhere and it has no transparency, WebP to JPG gives you a much smaller file.

Can I convert an animated WebP?
Only as a still: the first frame of an animated WebP becomes the PNG.

What happens to my files?
They travel over HTTPS to api.mochify.app, are converted in memory and discarded as soon as your download is ready. Nothing is written to disk and no logs contain your image data.

Bulk and automated WebP to PNG

Seller and Pro accounts convert up to 25 files per batch at up to 75MB each. The same conversion runs from the terminal with the Mochify CLI (mochify *.webp -p "convert to png"), from an AI agent through the hosted or local MCP server, and from the REST API:

curl -X POST "https://api.mochify.app/v1/squish?type=png" \
  -H "Authorization: Bearer $MOCHIFY_KEY" \
  --data-binary @logo.webp \
  -o logo.png
