Convert PNG to WEBP
This is the conversion that lets you shrink a transparent image without flattening it. WebP supports a full alpha channel, so logos and cut-outs stay usable while getting dramatically lighter.

How to convert PNG to WEBP
- Upload your PNG. Drag it in or browse. Several files at once is fine.
- Set the quality. 85 is a good default for graphics with sharp edges.
- Download. Take the files one by one or as a ZIP.
Supported formats
Accepts image/png. Produces image/webp. Files up to 50 MB, and up to 80 megapixels.
Your files stay private
Uploads are stored under a random name with no connection to the file you sent, and they are never served from a public directory. Input files are deleted within two hours and finished downloads within 24 hours. Nobody looks at them, and nothing is shared with anyone.

- Does transparency survive?
- Yes. WebP has a proper alpha channel, so transparent and semi-transparent pixels are preserved exactly. This is the main reason to choose WebP over JPG for a PNG.
- How much smaller will the file be?
- Commonly 50–80% smaller for screenshots and UI graphics, and often more for large flat-colour images. PNG spends a lot of bytes storing what WebP can describe far more compactly.
- Should I use lossy or lossless WebP?
- This tool uses lossy WebP, which is right for almost every web use. If you need pixel-exact output — a design source file, a diagram destined for print — stay with PNG.
- Do you keep my files?
- No. Files are stored on our server only while the conversion runs. Uploads are deleted within 2 hours and finished downloads within 24 hours, whichever comes first. We never open, inspect or share them.
