WebP: what it’s for

WebP is Google's modern image format built for the web: lossy and lossless modes, transparency, and even animation in a single format. It delivers JPG-equivalent quality at roughly two-thirds the file size, which is why performance-minded sites serve WebP by default.

Strengths

  • About 25–35% smaller than JPG at equivalent visual quality
  • One format covers lossy, lossless, transparency, and animation
  • Supported by all modern browsers — safe as a default web format
  • Our WebP exports use quality 0.85, tuned for invisible compression

Honest limits

  • Older desktop editors and some upload forms still reject WebP — convert back to JPG/PNG for those
  • AVIF compresses better still, so WebP is the compatibility pick, not the efficiency crown
  • Re-encoding a lossy WebP into JPG compounds compression artifacts
  • Animated WebP plays in browsers but few editors can retouch it

WebP FAQs

Should I convert my site images to WebP?

Usually yes — expect roughly a third smaller files than JPG with no visible difference, plus transparency support. Keep a JPG/PNG fallback only if you serve very old software.

What quality does Toolzum use for WebP?

Our converter exports WebP at quality 0.85, which is visually transparent for photos while keeping files small. PNG sources stay lossless-sharp.

Why won't my editor open a WebP file?

Some older editors predate WebP. Convert WebP to PNG or JPG first — both open everywhere — then edit.

Is WebP conversion private?

Yes. Files are converted with canvas APIs inside your browser and never uploaded to any server.
