About This WebP Converter
This browser-based WebP converter turns a single image (JPG, PNG, GIF, BMP, TIFF or WebP) into an optimized WebP file. WebP typically produces much smaller files than JPG or PNG at comparable quality, which speeds up page loads and improves Core Web Vitals such as LCP. Everything runs locally using the browser's Canvas API - your image is never uploaded to a server.
Key Features:
- Any Common Input: Convert JPG, PNG, GIF, BMP, TIFF or existing WebP images
- Adjustable Quality: Choose the WebP quality to balance file size and image fidelity
- Optional Resize: Cap the maximum width to shrink oversized images (aspect ratio preserved)
- Live Savings: See original vs. WebP size and the percentage saved instantly
- No Upload: Conversion happens entirely in your browser via the Canvas API
Use Cases:
- Shrink hero and product images to improve LCP and page speed
- Fix 'serve images in next-gen formats' warnings from Lighthouse or PageSpeed
- Convert a screenshot or photo to WebP before uploading to a CMS
- Compress confidential or unpublished images without uploading them anywhere
š Privacy-Friendly: Your image is decoded and re-encoded entirely in your browser. It never leaves your device.
Inspired by webp-crusher (MIT). This tool uses the browser's native Canvas API and requires no external image library.
ā ļø Disclaimer: Re-encoding drops EXIF, ICC color profiles and other metadata, and does not apply EXIF orientation. WebP encoding requires a modern browser (Chrome, Edge, Firefox, Safari 16.4+). Always verify the result before publishing.
