WebP Compressor
Compress WebP images online free — reduce WebP file sizes for faster page loading. Browser-based compression, your images never leave your device.
Last updated: 10 October 2026
Re-encode WebP files to shave another 10-35% off images that are already compressed. A 1.8MB WebP photo became 1.2MB at 85% quality, and a 450KB icon dropped to 310KB at 80% — modest but real gains for pages with many WebP assets.
WebP Compressor
Worked Examples
Tested re-encodes
- 1.8MB WebP photo at 85% quality → 1.2MB (33% further reduction)
- 450KB WebP icon at 80% quality → 310KB (31% smaller)
- Animated WebP files are not supported — pass them through unchanged
When to re-encode vs convert
- Keep WebP when the audience is modern browsers on your own site.
- Convert to JPG when the file travels: email, print shops, older software.
- Expect smaller gains than JPG→WebP — WebP is already efficient.
About WebP Compressor
Our WebP Compressor reduces WebP image file sizes while maintaining quality. WebP is already a compact format, but this tool can further optimize it for web use. Batch process up to 10 WebP files at once. We tested by recompressing a 1.8MB WebP photo at 85% quality, achieving a 1.2MB output — a 33% further reduction. A 450KB WebP icon compressed to 310KB at 80% quality, showing modest but meaningful gains even on already-optimized files.
Supported formats: WebP
Limits: Maximum 10 images per batch; Gains are typically 10-35% — WebP is already well-optimized; Animated WebP files are not supported; Browser canvas may struggle with WebP files over 15MB

How It Compares
Unlike Squoosh which is a single-image tool requiring manual quality adjustment each time, this tool supports batch processing of up to 10 WebP files simultaneously. Both tools process locally, but this one is faster for bulk workflows.
Privacy & Security
Because processing happens directly in your browser, your files and input are not uploaded to our servers.

About FreeDigitalToolkit →Frequently Asked Questions
Why compress WebP if it's already compressed?
WebP files can often be further optimized. This tool re-encodes the WebP with optimized settings, which can reduce file size by 10-30% additional.
Will re-encoding WebP reduce quality?
Like JPEG, WebP lossy compression degrades slightly with each re-encoding. At 85%+ quality, the difference is imperceptible on screens. Avoid going below 70% to prevent visible artifacts.
When should I use this vs converting to JPG?
If browser compatibility is not a concern, keep the file as WebP — it's more efficient than JPG. Convert to JPG only if you need to support very old browsers or specific software that doesn't read WebP.
What's the minimum quality setting I should use?
60-70% is the practical floor. Below that, WebP artifacts become noticeable, especially in areas with smooth gradients like skies and skin tones.
