Compress WebP
Trim already-modern WebP assets further when Lighthouse or your CDN still flags image weight.

WebP often beats JPEG at similar visual quality, but exports from design tools can still be oversized. This compressor re-encodes WebP with a quality target aimed at production sites that already standardized on the format.
Because WebP may be lossy or lossless depending on how it was saved, start with a mild pass. Oversqueezing product shots can muddy logos that looked fine in the source export.
If your asset is still a JPG or PNG, convert first with the dedicated converters, then compress. Older email clients that lack WebP support need a JPEG fallback—use webp-to-jpg when required.
How to use
- Upload a WebP file — Choose an existing .webp asset from your design export or prior conversion.
- Adjust compression strength — Lower quality for marketing banners; keep it higher for UI chrome and text-heavy shots.
- Compare before and after — Flick between previews focusing on edges and brand colors.
- Download the optimized WebP — Replace the heavy asset in your repo or CMS once satisfied.
- Validate in the real page — Hard-refresh the site to confirm perceived quality on target devices.
Use cases
- Performance budgets — Bring hero WebP files under a team’s kilobyte budget.
- App store screenshots — Lighten WebP store assets without rebuilding them from Photoshop.
- CDN re-uploads — Ship a smaller derivative when an earlier export was too generous.
Tips
- Prefer compressing from a high-quality master, not from a twice-converted thumbnail.
- Transparent WebP needs careful preview on both light and dark backgrounds.
- If browsers you support lack WebP, keep a JPEG/PNG alternate.
- AVIF may shrink further—try compress-avif when your stack supports it.

Use the jpg-to-webp tool for format conversion, then compress if needed.
Animated WebP handling varies; test a short clip before relying on it for production.
