How to use

Frequently asked questions
Why convert AVIF to WebP?
Some websites, blog platforms and apps accept WebP but not AVIF, which is newer. WebP keeps the file small and opens in more places. JPG opens almost everywhere, but the file is larger.
Will the WebP be larger than the AVIF?
Usually a little, because AVIF compresses better. Both formats are lossy, so converting compresses the image again, but at the default High quality the difference is hard to see. Transparent areas are kept.
How many files can I convert at once?
The site sets no limit on the number of files, but how many you can convert depends on your device's memory and speed. Files are processed one at a time and stay in your device's memory until you download them. Large batches or very large images may fail, especially on phones. If that happens, convert them in smaller groups.
Is the image file information kept?
No. Converting to WebP converts only the image: information such as the date, camera equipment and location is not carried over to the new file.
Are my files uploaded to an outside server?
No. Everything runs in your browser, so your files never leave your device. The page only downloads the tool's own code when you add the first file.
