About JPG to WEBP
JPG is the most widely used photo format; WebP is Google’s modern web format. Converting gives you much smaller files than JPG and PNG at the same quality, with transparency — perfect for websites.
Drop in one picture or hundreds and they are converted together with a live before / after preview that shows the new file size. Choose the quality, the colour for transparent areas, resize on the way, set the DPI and keep photo details — everything runs in your browser, so your images stay private.
Good for
- Making web pages load faster
- Saving storage space for large image libraries
- Smaller images for online shops and blogs
Tip: A quality of 75–85 is the sweet spot for websites.
Frequently asked questions
How much smaller is WebP?
Usually 25–35% smaller than JPG at the same visual quality, which makes web pages load faster.
Can I convert many JPG files at once?
Yes. Add as many as you like — they are all converted with the same settings, and you download them one by one or together as a ZIP.
Can I change the size or quality too?
Yes. Set the quality with the slider, and under “Resize and more” fit the pictures within a width and height, scale them by a percentage or set the DPI.
Can I convert to other formats?
Yes. Pick another format from the list — JPG, PNG, WebP, AVIF, GIF, BMP, TIFF or ICO.
Are my pictures sent to a server?
No. The WebP files are created in your browser, so your pictures never leave your device.
Does every browser support WebP?
Current versions of Chrome, Edge, Firefox and Safari all display WebP. Some older software and photo apps can't open it, so keep the JPG when you send files to other people.
