WebP is typically 25–35% smaller than JPG at the same quality, so converting speeds up websites and saves bandwidth.
Convert between JPG, PNG and WebP — multiple files at once
🔒 100% private — files are processed in your browser and never uploaded to any server.
For the web, usually yes — smaller files at similar quality. For maximum compatibility with old software, JPG is still safest.
Minimal at high quality settings. Convert from your best original rather than a heavily-compressed JPG to avoid stacking loss.
No software and no sign-up. The JPG-to-WEBP converter runs in your web browser, so it works on any device — Windows, Mac, Android or iPhone — straight from this page.
Yes. Drop in several images and they are converted together; a single file downloads directly, while a batch arrives as a ZIP.
No. Conversion happens entirely in your browser — your images never leave your device.

JPG — JPEG. JPEG is the universal photo format — nearly 30 years old and readable by every device, browser and app on earth. It uses lossy compression that is superb for photographs, keeping files small while looking clean, which is why cameras and phones default to it. Its weaknesses are that it cannot store transparency and it adds visible halos around sharp text and hard edges, so it is a poor choice for logos, screenshots and line art.
WEBP — WebP. WebP is a modern format from Google that supports both lossy and lossless modes, transparency and even animation. At comparable quality it is typically 25–35% smaller than JPG and much smaller than PNG, which is why it is now the default for fast-loading websites. Every current browser displays it, though some older desktop apps and upload forms still do not accept it.
Every modern browser supports WebP. If a specific old upload form rejects it, convert back to JPG.
Drop in as many JPG files as you need and they are converted together, arriving as a single ZIP. Because the work happens on your own device rather than on a server, a batch is limited only by your own memory, and there is no queue, no daily cap and no sign-up. Private or sensitive images stay entirely with you.
Need a different conversion, or want to process a batch? The full image converter handles JPG, PNG and WebP together, and you can pair it with the compressor if the result also needs to hit a size limit.
The same JPG reader feeds each conversion below, so whichever output you pick the file is still decoded on your own device.
If what you are starting from is not a JPG, open the converter that matches your own file instead.
Working through a pile of files? The full image converter handles a whole batch at once.
