Supports JPEG, PNG, WebP — processed entirely in your browser
Why Compress Images?
Large images are the #1 cause of slow websites. Google's Core Web Vitals penalise sites with slow-loading images in search rankings. Compressing images before uploading them to your website, social media, or email can reduce file size by 50–85% with no visible quality loss.
How to Use This Image Compressor
- Drag and drop one or more images into the upload area, or click to browse. Supports PNG, JPEG, and WebP.
- Adjust the quality slider — lower values mean smaller files but reduced quality. 70–85% is usually the sweet spot for web images.
- Compare the before and after preview to make sure quality is acceptable.
- Download images individually or as a ZIP file for batch compression.
Frequently Asked Questions
Is this image compressor really free?
Yes. No limits, no watermarks, no signup required. Compress as many images as you want.
Are my images uploaded to a server?
No. All compression happens locally in your browser using the Canvas API. Your images never leave your device.
What's the best format to use?
WebP offers the best compression for web use — up to 34% smaller than JPEG at the same quality. Use PNG only when you need transparency or pixel-perfect sharpness (like logos and icons).
