Drop your WebP image into the box above — straight from your phone, camera or downloads folder.

2

Compress

The target is pre-set to 100 KB and WebP output is selected. Adjust anything, then hit Compress image.

3

Download

Preview the result, check your savings, and download — guaranteed under your target size.

WebP is efficient — and still compressible

WebP is the modern image format: 25–35% smaller than JPEG at equal quality, with transparency baked in. So why compress it further? Because 'efficient' is not the same as 'optimized for your use'. A WebP saved at 95% quality for archival can often drop to a web-ready size with zero visible change.

This page pre-selects WebP output, so your image stays WebP end to end — transparency intact, alpha channel preserved, just fewer bytes. It is the fastest win available for sites already serving WebP that want their Lighthouse scores even higher.

Tips

  • Output is pre-set to WebP. Your image stays in the WebP format throughout — no conversion surprises. You can switch to JPEG anytime.
  • Transparency is preserved. Unlike JPEG conversion, WebP-to-WebP keeps the alpha channel perfectly — logos and overlays stay intact.
  • Target by display size. A 1200px-wide WebP hero at 100KB is the classic fast-page recipe.
  • Watch for animated WebP. Animation is not preserved — the tool processes the first frame. Keep animated files away from this compressor.

Common uses

  • Website hero images — even lighter WebP for top Lighthouse scores.
  • WebP thumbnails — tiny previews that load instantly.
  • App assets — smaller bundles for web and hybrid apps.
  • Ad creatives — hitting strict KB caps on ad platforms.

Frequently asked questions

Is it worth compressing WebP if it is already small?

Often yes. Many WebP files are saved at unnecessarily high quality — recompressing to a sensible target can cut another 30–60% with no visible difference, which matters for page speed.

Will my WebP keep its transparency?

Yes. Output is pre-set to WebP, which preserves the alpha channel perfectly — unlike converting to JPEG, which would flatten transparency to white.

What about animated WebP files?

Animation is not preserved; the tool processes the first frame as a still image. Do not use this compressor on animated WebP files you intend to keep animated.

Where is WebP supported?

All modern browsers — Chrome, Edge, Firefox and Safari 14+ — display WebP natively. For maximum compatibility with older systems, you can switch the output to JPEG.

WebP or JPEG for my website?

WebP, when your audience uses modern browsers — it is 25–35% smaller at equal quality. JPEG remains the fallback for legacy upload forms and old software.
