About this tool
JPG to WebP Converter
Convert JPG to WebP right in your browser. JPG is the most widely accepted photo format, with small files but no transparency, while WebP is Google's modern web format, much smaller than JPG or PNG, but not accepted by some apps and upload forms. WebP files are typically 25–35% smaller than JPG at the same visual quality, which makes web pages load faster.
Add one picture or a whole batch. Each one is converted at its original size, with a quality slider if you want smaller files, and you can download them one by one or all together as a ZIP. Some older apps and upload forms don't accept WebP, so keep the JPG if you need it elsewhere.
Everything happens on your phone or computer, so your images are never uploaded to a server. There's no sign-up, no limit and no watermark.
