Make WebP images smaller for a faster website, by quality or to an exact size like 100 KB. Transparency stays and nothing is uploaded - still on JPG? JPG to WebP converts first.
Compressing...
Drag across the picture to compare. Left: original - right: compressed.
It depends on how the file was made. Lossless WebP and WebP saved at quality 90-100 shrink a lot: our 629 KB lossless sticker sample becomes a fraction of that at quality 80.
A WebP that was already saved at a low quality has little left to give. In that case the tool keeps your original instead of making it bigger, and only drops hidden EXIF and XMP data.
A 4000 px image shown 1200 px wide wastes bytes. The Web 1920 px preset fixes that in the same step.
Many teams aim for under 200 KB per hero image and under 100 KB for content images.
WebP stores alpha, so stickers and logos keep their see-through edges - no PNG needed.
Want even smaller files for modern browsers? Try WebP to AVIF. Need a format that opens everywhere? WebP to JPG or WebP to PNG.
Each format has its own tricks, so each has its own tool: Compress JPG for photos, Compress PNG for screenshots and logos, Compress AVIF for the newest web format and Compress HEIC for iPhone photos.
Drop it into the box above. The Balanced level (quality 80) usually cuts lossless or high-quality WebP files by more than half. For an exact limit, open Target file size.
WebP compression is lossy, but at quality 75-85 the difference is very hard to see. Check it yourself with the before and after view at 100%.
Yes. Transparent and semi-transparent areas stay exactly as see-through as before.
Not yet - animated WebP files are kept untouched so the animation keeps playing. For animations, Compress GIF may help if you can use a GIF.
It was probably saved at a low quality already. Rather than making it bigger, the tool keeps your original and only removes hidden EXIF and XMP data.
Chrome, Edge, Firefox and Opera can save WebP files. Safari can open WebP but cannot save it yet, so please use another browser on a Mac or iPhone.
No. Your images are compressed inside your browser and never leave your device.
