Compress Images Online
Shrink image file sizes dramatically while keeping them looking great. Lower the quality and watch the file size drop in real time, then download the optimized image â all in your browser.
How it works
- Re-encodes the image at your chosen quality
- WEBP usually beats JPG at the same quality
- Live before/after size comparison
- No visible loss at 70â85% for most photos
Quality vs. size
Around 75% quality is the sweet spot for photos â large size savings with little visible difference. Drop lower for thumbnails where size matters most.
Private & Processed Locally
Compression runs entirely in your browser; your image is never uploaded.
Frequently Asked Questions
Common questions about the Image Compressor.
How much smaller will my image be?
It depends on the quality you choose; 75% quality often cuts file size by half or more with little visible difference.
Does it reduce quality?
You control the quality. WEBP usually gives smaller files than JPG at the same quality.
Is it private?
Yes. Everything runs in your browser using the Canvas API and your image is never uploaded to a server.
