How to Compress Images for Web
Steps
Open FastEdit
Go to fastedit.net. No installation or account required.
Drop your images
Drag and drop one or more images onto the editor. Use batch mode for an entire folder. JPEG, PNG, WebP, AVIF, and other formats are all accepted.
Choose the optimal output format
WebP offers the best balance of quality and size for modern browsers. AVIF is even smaller but has less browser support. Use JPEG for maximum compatibility.
Set dimensions
Resize to the actual display size on your site. Serving a 4000px image for a 800px container wastes bandwidth. Set the width to match your largest display breakpoint.
Adjust quality
For photographs: quality 75-85 in WebP or JPEG is visually identical to uncompressed on screen. For graphics and text: use lossless WebP or PNG.
Export optimized images
Click Export. Your optimized images download ready to deploy to your website or CDN.
Tips
- Resize first, compress second. Serving images at their display size is the single biggest optimization.
- WebP at quality 80 is typically 60-70% smaller than unoptimized PNG and 25-35% smaller than optimized JPEG.
- Use the HTML <picture> element to serve WebP with a JPEG fallback for older browsers.
- For hero images, quality 80-85 is usually sufficient. For thumbnails, you can go as low as 60-70 since they display small.
- Batch process your entire image library to apply consistent optimization across your site.
