Compress WebP Images — Offline, No Upload
Even WebP images can be further optimised; this tool reduces WebP file sizes for better performance without uploading to any server. Get smaller WebP files for faster websites while keeping your images completely private.
WebP is already efficient, but if you need to squeeze every byte for performance-critical pages, this tool lets you re-compress WebP images with a target quality or file size — all processed locally in your browser.
