What WebP is good at
WebP was designed for the web. It can store photos with lossy compression, graphics with lossless compression, and transparency in both. At a similar look, lossy WebP is commonly 25 to 35% smaller than JPG, and lossless WebP is usually smaller than PNG. All current browsers display it.
Compress or convert
- Compress a WebP file: add it and keep the output on WebP. Quality 75 to 80 is a good start.
- Convert JPG or PNG to WebP: add them and select WebP as the output format. For batches with ZIP download there is also the JPG to WebP converter.
When not to use WebP
Some government portals, print shops, marketplaces and older programs still accept only JPG or PNG. If an upload is refused, convert back with the WebP to JPG converter, or use the JPG compressor.
Settings that work
- Photos on a site: quality 75 to 80, Max width 1,920.
- Graphics with transparency: quality 85, or accept a little more size for clean edges.
- Thumbnails: Max width 600 and quality 70.
