Reduce image file size without losing visible quality. Perfect for websites, emails and social media.
JPG, PNG, WebP supported
Large images slow down websites, increase email bounce rates, and use unnecessary storage. Compressing images at 70–80% quality typically reduces file size by 50–70% with no visible quality difference to the human eye.
The Image Compressor reduces the file size of JPG, PNG, and WebP images using browser-based compression. Drag and drop your image, adjust the quality slider, and download the compressed version instantly. Everything runs locally — your image never leaves your device.
| Quality Setting | Typical Size Reduction | Visual Quality |
|---|---|---|
| 90% | 20-30% | Excellent — virtually identical to original |
| 80% (recommended) | 40-60% | Very good — no visible difference to most people |
| 70% | 55-70% | Good — slight compression visible on close inspection |
| 60% | 65-75% | Acceptable — compression visible, especially around text |
| 50% or lower | 75-85% | Noticeable quality loss — use only for thumbnails |
What image quality setting should I use?
80% is the recommended starting point for most purposes — it reduces file size by approximately 50-60% while maintaining excellent visual quality that most people cannot distinguish from the original. For product photos or professional images, use 85-90%. For thumbnails or small preview images, 60-70% is acceptable.
Does compressing an image reduce its dimensions?
This tool reduces file size while keeping the same image dimensions (width × height). Only the data representing each pixel is compressed, not the number of pixels. To reduce dimensions (resize), use the browser's built-in screenshot or photo editing tool, or a dedicated resize tool.
