What is WebP Compressor?

Optimize WebP images for the web. Optimize already-encoded WebP files down even further. Recompress WebP assets served from your CDN or CMS. A smaller WebP that decodes in the same browsers.

All processing happens locally in your browser. Your images are never uploaded to any server.

Key Features

  • Fine-grained quality slider from 10 to 95
  • Option to strip EXIF/metadata from WebP containers
  • Converts PNG/JPG source to WebP if you drop them in

Common Use Cases

  • Optimizing existing WebP images further for faster web delivery
  • Compressing WebP screenshots and graphics before deployment to production
  • Fine-tuning WebP quality settings to find the smallest acceptable file size
User Guide

How to use this tool

The WebP Compressor is a focused tool for optimizing existing WebP assets. It re-encodes each file at a chosen quality level so you can rebalance an old library that was originally exported at conservative bitrates, or shrink assets that were converted at "safe" defaults.

How to use it

Drop one or many .webp files onto the upload zone. The tool decodes each image, redraws it onto a canvas, and asks the browser to re-encode the pixels at the quality level you configure. Sizes 78–2% typically yield the best size/quality tradeoff for photography.

A live report shows original vs. compressed size and the percentage saved. Download individual files or bundle every result into a ZIP for uploading to your CDN.

  • Configurable quality — from aggressive to near-lossless
  • Preserves alpha transparency automatically
  • Batch processing with per-file savings breakdown
  • ZIP export for easy CDN sync

Advanced considerations

The browser WebP encoder does not expose the full libwebp preset system, but it does apply excellent defaults. Empirically, re-encoding a WebP file at 78% quality produces indistinguishable visuals at 30–0% smaller file sizes for most photographs.

If your source WebP was created from a JPG, remember that you are compressing an already-compressed image. Two rounds of lossy compression can accumulate artifacts, so keep an untouched original whenever possible.

Frequently Asked Questions

Is re-compressing WebP lossy?

Yes, if you use a lower quality than the source. Use the side-by-side preview to balance size and quality.

Does it produce animated WebP?

No — only the first frame of animated inputs is kept.

Why compress an already-optimized WebP?

WebP files exported from design tools often use suboptimal encoding settings. Re-compressing with precise quality control can reduce file size by another 10–30% without noticeable quality loss.

What quality should I target?

For photographic WebP images, 75–85% quality is typically ideal. For graphics, logos, and screenshots, consider lossless WebP or higher quality (90%+) to preserve sharp edges and text.

Can I convert JPG to WebP and compress at the same time?

Use our Image to WebP converter first, then this compressor for fine-tuning. Alternatively, the converter also allows direct quality control during JPG/PNG to WebP conversion.

Is this tool free to use?

Yes. This tool is completely free with no sign-up, no watermarks, and no daily limits. All processing runs locally in your browser.

Can I compress lossless WebP files?

Yes. Set quality to 100% to trigger the lossless encoder path.

Does compression preserve animation?

No — animated WebP is stripped to its first frame. For animation optimization, use a dedicated video tool.
