WebP files are typically 25–35% smaller than JPG/PNG — better Core Web Vitals and SEO.
Drop a whole folder of images and convert them all in one go.
Conversion uses your browser's built-in encoder — images stay on your device.
WebP is a modern image format from Google that delivers the same visual quality as JPG and PNG at a much smaller file size — usually 25–35% lighter. Smaller images load faster, which improves your page speed, Core Web Vitals and search rankings, and saves bandwidth. It's supported by every modern browser.
This tool converts your images using your browser's native WebP encoder, so there's no upload, no account and no limit. It's perfect for web designers, agencies and bloggers optimising images before publishing.
WebP supports both lossy and lossless compression in a single format, and typically produces files 25–35% smaller than an equivalent-quality JPEG. It also does something JPEG cannot: carry an alpha channel, so a transparent logo does not need to be a much larger PNG.
The trade-offs are worth knowing before converting a library. Lossy WebP is a generational format like JPEG, so re-encoding an already-lossy JPEG stacks one set of compression artefacts on another — converting from the original wherever possible is the difference between a smaller file and a worse one. Support is now effectively universal in current browsers, but some desktop applications and older print workflows still expect JPEG or TIFF, so WebP is a delivery format rather than an archival one.
