Why use WebP?
WebP is Google’s image format. According to Google’s study, lossy WebP files are 25 to 34% smaller than JPG at equivalent quality (SSIM) and supports transparency like PNG. Every modern browser displays WebP, and Google PageSpeed recommends it for faster pages.
Which settings should I pick?
Some starting points:
- Website or blog: WebP, quality 75 to 82, longest edge 1600 to 2000px.
- Facebook or Zalo: JPG, longest edge 1920px, under 1 MB.
- Email and documents: longest edge 1280px, under 300 KB.
- Images with text or logos: keep quality at 85 or higher.
Metadata is removed too
Compressed images are redrawn from scratch, so EXIF, GPS, XMP and C2PA AI labels are all dropped. You get a lighter file and keep your location private.
Frequently asked questions
Is it free?
Yes. Free, unlimited, no sign-up and no ads.
How do I compress an image under 1 MB or 200 KB?
Enter the number in "Max file size". The tool finds the highest quality that stays under that limit. If it is still too big, lower the max edge.
Does PNG to WebP keep transparency?
Yes. WebP and PNG keep transparency. Only JPG does not, so transparent areas become white.
Are images uploaded for compression?
No. Compression uses your browser’s built-in image encoder, and images never leave your device.
Why is the result bigger than the original?
This happens when the original is already heavily optimised, or when a flat-colour image is converted to JPG. Try WebP, lower quality or set a max file size. The tool flags results that are not smaller.
