Compress WebP Images Online
Optimize WebP images for faster page loads. Compresses lossy and lossless WebP variants in your browser.
Why this matters
WebP is already 25–35% smaller than equivalent JPG or PNG, but most exporters use overly conservative defaults. Recompressing trims another 20–40% off, which means faster Core Web Vitals scores and lower CDN bandwidth bills.

Frequently asked questions
Will all browsers display compressed WebP?
WebP is supported by all modern browsers (Chrome, Firefox, Safari 14+, Edge). For wider compatibility, convert to JPG first.
Does WebP support transparency after compression?
Yes — WebP supports alpha channels and they’re preserved during compression.
WebP vs AVIF: which is better?
AVIF compresses slightly better but has weaker tooling support. WebP is the safer, faster choice today.
Is the compression lossy?
Lossy by default for the best size reduction. Output is visually indistinguishable for almost every image.
Are WebP files uploaded?
No. Compression runs in-browser; nothing leaves your device.
How small can a WebP get?
Most WebP files shrink another 20–40% from their original export.
