WebP Compressor

Shrink WebP Files Further

Encode any image to highly-compressed WebP with quality control.

WebP is already smaller than JPG or PNG, but most WebP files in the wild were exported with default settings and can be shrunk further. Drop a WebP, get back a smaller WebP at matching quality. Useful for tightening up website assets where every kilobyte matters.

WebP compression modes

Lossy (default): like JPG, discards visually imperceptible detail. Quality 75–85 is the sweet spot for most photos.
Lossless: like PNG, every pixel preserved exactly. Saves 20–30% over PNG for graphics.
Near-lossless: visually identical to source but slightly smaller than full lossless. Best for graphics with subtle gradients.

When does re-compression help

Default-export WebPs from design tools. Photoshop, Sketch, Figma all export at q=80–85; can shrink further at q=75 with no perceptible difference.
WebPs from CMS uploaders. Many CMS plugins export at conservative quality. Re-encode for performance.
Animated WebPs. Per-frame compression options can dramatically shrink animations.

Need a different format?

Convert WebP back to universally-compatible JPG with our WebP to JPG tool, or to transparent PNG with WebP to PNG. To go to even smaller AVIF (best modern format) we have a converter rolling out.

Browser support

WebP is supported in every modern browser (Chrome, Firefox, Safari 14+, Edge). Coverage is ~96% of global users. For the remaining 4%, serve a JPG fallback — most CDNs (Cloudflare, Cloudinary, Imgix) handle this automatically with the <picture> element.

Frequently asked questions

Is repeated re-compression bad?

Each lossy pass loses a tiny bit of quality. For one or two passes the difference is invisible. For many passes (10+) artefacts accumulate.

Lossless vs lossy — which to pick?

Photos: lossy. Graphics, logos, screenshots: lossless. Mixed content: try both and pick the smaller one that still looks right.

Animated WebP supported?

Yes — per-frame compression. We preserve the animation timing.

Maximum file size?

25 MB per file.

What's the difference between WebP and AVIF?

AVIF is newer, slightly smaller at equal quality, but with less browser coverage (~92% vs ~96%).

Can I batch process?

Yes — see <a href='/tools/compression/batch-optimize/'>Batch Optimize</a> for whole-folder compression.

Will it strip metadata?

Yes by default. Toggle to keep EXIF if you need it.

Are files private?

Yes — deleted within 24 hours, never used for training.
