Reduce image file sizes by up to 90% without visible quality loss. Our image compressor works entirely in your browser — your files are never uploaded to any server, keeping them completely private.
Drop your images into the upload area, adjust the quality slider, and click Compress. The tool uses your browser's built-in Canvas API to re-encode images at your chosen quality level. Click any result to download the compressed version instantly.
JPEG, PNG, WebP, and BMP files up to 10 MB each. Batch processing is supported — compress multiple images at once.
Large image files slow down websites, eat up storage space, and take longer to share via email or messaging apps. Image compression reduces file size while maintaining visual quality that is virtually indistinguishable from the original. For web developers, compressed images are essential for fast page load times, better Core Web Vitals scores, and improved SEO rankings. Google has confirmed that page speed is a ranking factor, and images are often the largest assets on any webpage.
There are two main approaches to image compression. Lossy compression (used by JPEG and WebP) discards some image data to achieve dramatically smaller file sizes — often 70-90% reduction. The quality slider in this tool controls how aggressively data is removed. At 75-85% quality, the difference is nearly invisible to the human eye. Lossless compression (used by PNG) reduces file size without losing any data, but achieves smaller reductions — typically 10-30%.
For photographs and complex images, JPEG at 75-80% quality offers the best balance of size and visual quality. For graphics, logos, and images with text, PNG is better because it preserves sharp edges. WebP provides excellent compression for both types but has slightly less universal browser support. When compressing images for the web, aim for file sizes under 200 KB for hero images and under 100 KB for thumbnails.

| Screenshot (1920×1080) | 1.2 MB | 185 KB | 320 KB | 73–84% |
| Social Media (1080×1080) | 680 KB | 95 KB | 165 KB | 76–86% |
| Product Photo (2000×2000) | 4.8 MB | 720 KB | 1.3 MB | 73–85% |
| Website Banner (1920×600) | 850 KB | 120 KB | 210 KB | 75–86% |
No. Compression reduces file size, not pixel dimensions. Your image keeps its original width and height. If you need to change dimensions, use our Image Resizer tool.
No limit. Since everything runs in your browser, you can compress as many images as you want. The only constraint is your device's available memory.
Absolutely not. All compression happens locally in your browser using JavaScript. Your files never leave your device — there is no server-side processing at all.
