Image to WebP
Smaller files for faster sites.
Runs entirely in your browser. Nothing you enter or upload leaves your device.
What the WebP converter does
The WebP converter re-saves your images in the WebP format, which was designed for the web. It can compress photos like JPG does and keep transparent backgrounds like PNG does, often in a noticeably smaller file than either.
It is mainly useful if you run a website or online shop. Lighter images mean pages appear sooner, use less of your visitors’ mobile data and take up less room on your server. Besides JPG and PNG, it also accepts GIF, BMP and AVIF files.
How to use the WebP converter
Turn JPG and PNG images into WebP, a modern format that is usually much smaller at the same quality.
- Drop up to 30 JPG or PNG images, or click to choose them.
- Set the quality. 75–85% suits most photos; 100% keeps detail for graphics and screenshots.
- Download each file, or all of them at once. The total saving is shown above the list.
Understanding the results
Each result card shows the image’s dimensions, its new size and the percentage it shrank or grew compared with your original. The line above the list totals the whole batch. Moving the quality slider (10–100%, starting at 80%) converts everything again, so you can find the lowest setting that still looks right.
The converter never changes an image’s width or height. If your pictures are also larger than they will ever be displayed, the Image Compressor can save WebP and cap the width in one step, which usually saves far more than quality alone.
Questions
Do all browsers show WebP?
Yes, all current browsers display WebP, including Safari since version 14.
Can every browser create WebP files?
Not every browser can write WebP from a web page. If yours can’t, a notice appears at the top of the tool and the files are not converted, so try a different browser.
Does WebP keep transparency?
Yes. Transparent PNGs stay transparent as WebP.
Why is a WebP file bigger than the original?
Small or already heavily compressed images sometimes grow. The card flags any file that got larger. Lower the quality or keep the original for those.
What happens to an animated GIF?
It becomes a still WebP of a single frame.
Where does the conversion happen?
On your own device. Your browser does the encoding, so the images are never uploaded.
