About this tool
WebP is already efficient, but many WebP files exported from design tools, CMSs, or older converters are saved at higher quality than a modern site or upload really needs. This tool re-encodes existing WebP images with a fresh encoder pass, letting you choose a lower quality factor, a rough size budget, or a percentage of the original. Alpha transparency is preserved when present. Everything runs locally in your browser so the source stays on your machine.
FAQ
This tool compresses WebP but does not convert away from WebP. Use a dedicated converter for that.
Yes, WebP alpha is preserved when the source has it.
Only the first frame of animated WebP files will be compressed; use a video tool for animation workflows.
Many WebP files are saved at quality 90+ by default and can lose 30–60% more size with a lower quality that still looks great.
No. WebP recompression stays in your browser.

- Reducing hero images and thumbnails on modern websites
- Serving lighter WebP files through a CDN
- Re-compressing WebP files pulled from CMS media libraries

Limitations
- Only WebP inputs — convert first if you have JPG, PNG, or AVIF.
- Roughly 25 MB per file.
- Lossy re-encoding after multiple passes can visibly soften details; compress from the highest-quality source when possible.
- Sizes are approximate targets, not exact byte counts.
