How it works
How to use the PNG to WebP tool
- 1
Add PNG images
Drop one or many files onto the upload area, or click to browse your device.
- 2
Adjust if needed
Set the WebP quality. The default is a great balance of size and sharpness.
- 3
Download
Download each WebP individually, or all of them together as a ZIP file.
Transparency is preserved
Unlike JPG, WebP supports an alpha channel, so logos, icons and cut-out product photos keep their transparent backgrounds. At the same time, WebP files are frequently 50–80% smaller than the equivalent PNG, which makes them a great fit for websites and apps.
Limitations
We’d rather be upfront about what this tool can’t do yet:
- Output is lossy WebP; for pixel-perfect archiving keep the original PNG.
- Requires a browser that can encode WebP (Chrome, Edge, Firefox).
FAQ
Frequently asked questions
Are my images uploaded to a server?
No. Conversion uses your browser's built-in image engine, so your pictures never leave your device.
Will my transparent PNG stay transparent?
Yes. WebP keeps transparent and semi-transparent pixels.
Can WebP be used in WordPress and Shopify?
Yes. Both platforms support WebP uploads, as do all modern browsers.
What quality should I choose for graphics?
Use 85–95% for logos and illustrations with crisp edges; lower values are fine for photos.
