Convert PNG and JPG images to WebP right in your browser. The conversion runs on your device, so files do not get uploaded — faster and more private.
You can process one image or a batch of files. Choose compression level to balance quality and size, then download optimized images ready for the web.
Ideal for site owners, editors and developers who want to reduce page weight and speed up load times without changing visual quality.
How do I convert many JPG or PNG files to WebP at once?
Switch to "Batch" mode, upload the images you need (drag and drop several at once works too), and adjust the compression strength with a single slider — all files process together and are ready to download.
How much smaller is WebP compared to JPG?
WebP typically saves 25-40% in file size at comparable visual quality — the exact number depends on image content and the chosen compression level.
Should I convert to WebP or go straight to AVIF?
WebP has wider support (all modern browsers since 2020) and is enough for most sites. AVIF gives slightly smaller files but weaker support in older browsers — the tool lets you download both and compare.
