WebP is an image format that Google introduced in 2010 as a successor to JPG and PNG. It combines the advantages of both: it can compress lossily (like JPG) and losslessly (like PNG), and it supports transparency.
Why is WebP smaller?
WebP uses a more advanced compression algorithm than JPG (based on the VP8 video codec). On average a WebP file is:
- 25-35% smaller than a comparable JPG
- 26% smaller than a comparable PNG (lossless)
At equal visual quality the file is therefore considerably lighter — ideal for websites where loading speed matters.
Does every browser support WebP?
Yes. All modern browsers support WebP:
- Chrome: from version 23 (2012)
- Firefox: from version 65 (2019)
- Safari: from version 14 (2020)
- Edge: from version 18
- iOS Safari: from iOS 14
Old browsers (IE11, Safari before 2020) cannot open WebP. For those cases you serve a JPG fallback via the HTML picture element.
When should you use WebP?
Use WebP when placing images on a website. It reduces loading time without visible quality loss. Use JPG when emailing the image or uploading to a platform that does not accept WebP.
Does WebP support transparency?
Yes. Lossless WebP supports an alpha channel (transparency), just like PNG. For logos or icons with a transparent background, lossless WebP is a good choice — smaller than PNG, with full transparency.
How do you convert to WebP?
1. Go to the format conversion tool.
2. Drag your JPG or PNG here.
3. Choose WebP as the target format.
4. Download the converted file.
Frequently asked questions
Can I open a WebP file in Photoshop?
Not by default. You need a plugin (e.g. WebPShop from Google). Many other modern editors (GIMP, Affinity Photo, Figma) open WebP natively.
Is WebP suitable for printing photos?
No. Use TIF or PDF for print quality. WebP is optimised for screen display.
Does WebP also work for animated images?
Yes. WebP supports animation, just like GIF, but much smaller. Browser support is wide. As an alternative to animated GIFs, animated WebP is interesting for web developers.
