About WebP Compression
WebP is Google's modern image format that provides 25-35% smaller files compared to JPEG at equivalent quality. It supports both lossy and lossless compression, plus transparency. img.awajis uses the official libwebp encoder compiled to WebAssembly.
Browser Support
WebP is supported by all modern browsers including Chrome, Firefox, Safari, and Edge. It's the recommended format for web images when you need the best balance of quality and size.
Working with JPEGs instead? Try our JPEG compressor powered by MozJPEG, or convert JPGs to WebP for the best compression.
Frequently asked questions
Why use WebP over JPEG or PNG?
WebP files are typically 25–35% smaller than JPEG and far smaller than PNG at similar quality, while supporting both lossy compression and transparency.
Does WebP support transparency?
Yes. Unlike JPEG, WebP can store an alpha channel, so it replaces PNG for transparent graphics at a smaller size.
Do all browsers support WebP?
All modern browsers do. For very old software, convert to JPG or PNG using the matching converter tool.
Is processing private?
Yes — your images are compressed locally and never uploaded.
What WebP quality should I use?
Around 80 balances size and quality for most images. Photos tolerate lower settings well, while sharp graphics and text look best at 85–90.
Is WebP really smaller than JPEG?
Yes — at the same visual quality WebP is typically 25–35% smaller than JPEG, and unlike JPEG it also supports transparency.
Does re-compressing a WebP lose quality?
Lossy WebP discards a little more detail each time it is re-encoded, so compress from the original source whenever possible.
Can I compress an animated WebP?
This tool focuses on still WebP images. Animated WebP is best exported at the right quality from its source rather than re-compressed here.
