About the Image Compressor
The Image Compressor lets you shrink JPG, PNG and WebP files directly in your browser, saving up to 90% of space while keeping visual quality intact.
It’s perfect for web designers, small business owners, bloggers and anyone who wants faster page loads, lower bandwidth usage, or just a tidy media library.
With our simple drag‑and‑drop interface you can compress images on the fly without any software install.
How to use the Image Compressor
- Drag and drop your JPG, PNG or WebP files (up to 50 at a time) onto the drop area or click to browse.
- Adjust the Quality slider (default 80) or set a Max Width if you want to resize.
- Click 'Compress' and watch the preview thumbnails update.
- Download each image individually or click 'Download ZIP' to get all compressed files at once.
Tips & benchmarks
- For photos, set quality to 80–85 to keep a natural look while reducing size by ~70%.
- PNG is ideal for images with transparency or flat colours; otherwise convert to JPG or WebP for up to 50% smaller files.
- Use the Max Width setting to match your largest display size; a 4000 px photo displayed at 800 px can be compressed by 75% without visual loss.
- Compress all images in a ZIP to speed up uploads to CMS or cloud storage.
- Check the 'Show difference' toggle to verify compression does not introduce artifacts; a 5‑point PSNR is generally acceptable.
