How Image Compression Works
Image compression reduces file size by removing data that isn't visually important. At 80% quality, most JPEG images lose less than 1% of visible detail while reducing file size by 60-80%. This tool uses your browser's built-in image encoder — the same one used by every major website.
When to Compress Images
- Website performance — Smaller images load faster, improving SEO and user experience
- Email attachments — Stay under email size limits
- Social media — Faster uploads, no platform re-compression artifacts
- Storage — Fit more photos on your device or cloud storage
- Form uploads — Many forms limit file sizes to 1-5 MB
Output Formats
- JPEG — Best for photographs. Lossy compression, smallest files, no transparency.
- PNG — Best for graphics, screenshots, and images needing transparency. Lossless, larger files.
- WebP — Modern format with better compression than JPEG and PNG. Supports transparency. Not supported by all older software.
Privacy
This tool runs entirely in your browser. Your images are never uploaded to any server. The compression uses the HTML Canvas API built into your browser. No data leaves your device.
