PNG and JPG to WebP, instantly

WebP is a modern image format developed for the web that delivers excellent quality at a fraction of the size of older formats. Converting your PNG graphics and JPG photos to WebP is one of the easiest ways to make a website faster and improve search rankings, since page speed is a ranking factor.

Control the quality and size trade-off

The Export tab shows a live estimate of the output file size as you move the quality slider, so you can find the sweet spot between sharpness and download size without guessing or re-exporting repeatedly. For photos, a quality around 75–85% is usually indistinguishable from the original.

WebP vs AVIF vs PNG vs JPG

WebP is the safe modern default, but you can also export AVIF for even smaller files on supported browsers, or stick with PNG/JPG when you need maximum compatibility. See our guide to converting PNG to WebP for a deeper comparison, or jump to compressing images if your goal is purely a smaller file.

FAQ

Questions & answers

Why convert to WebP?

WebP typically produces files 25–35% smaller than JPG or PNG at the same visual quality, which means faster page loads and better Core Web Vitals. It also supports transparency like PNG.

Does converting to WebP lose quality?

WebP supports both lossy and lossless modes. At a high quality setting the difference is usually invisible while the file is much smaller. Lower the slider for even smaller files.

Is WebP supported everywhere?

WebP is supported by all modern browsers (Chrome, Firefox, Safari, Edge). For maximum compatibility with very old software, keep a PNG or JPG copy.

Are my images uploaded to convert them?

No. Conversion happens entirely in your browser using the Canvas API, so your images stay private and the tool even works offline.
