Compress WebP Files
WebP is already one of the most efficient image formats on the web, but unoptimized WebP files — especially those exported from design tools or converted from high-quality originals — can still be much larger than necessary. Pixotter compresses WebP files with adjustable quality, letting you squeeze even more savings from an already-efficient format. Everything happens in your browser.
When to Compress WebP
- Website performance — Even WebP images benefit from quality tuning; most exports use higher quality than needed
- CMS uploads — WordPress, Shopify, and other platforms increasingly accept WebP; compress before uploading to save storage
- Batch optimization — Convert and compress entire image libraries to WebP for maximum web performance
- Email and messaging — WebP is supported in most modern email clients and chat apps
WebP vs JPEG vs PNG
WebP typically produces files 25-35% smaller than JPEG and 25-50% smaller than PNG at equivalent visual quality. It supports both lossy compression (like JPEG) and lossless compression with transparency (like PNG). If your audience uses modern browsers, WebP is almost always the best choice. For maximum compatibility with older software, consider converting to JPEG or converting to PNG.
How It Works
Drag and drop one or more WebP images. Batch processing handles up to 20 files at once.
Use the quality slider to balance file size and visual quality. WebP supports both lossy and lossless modes.
Download individual files or grab them all as a ZIP. Check before/after to verify quality.
