How It Works
This free online image compressor reduces your file sizes entirely in your browser — no image is ever sent to a server.
-
1. Choose your image
Click the upload area or drag and drop any JPG, PNG, WebP, GIF, or BMP from your device. It loads instantly into the tool — nothing leaves your computer.
-
2. Set the quality level
Use the quality slider to decide how aggressively to compress. Lower values shrink the file further; higher values preserve more detail. You can also pick the output format — WebP usually gives the best compression, JPG is the most widely compatible, and PNG is lossless.
-
3. Compress in your browser
Hit Compress Image and your browser re-encodes the photo at your chosen quality — no upload, no waiting, just an instant result.

Frequently Asked Questions
Are my images uploaded to a server?
No. All processing happens locally in your browser. Your images are never sent to or stored on any server.
Is this image compressor free?
Yes, completely free. No account required, no watermarks, and no hidden charges.
What quality setting gives the best results?
For most photos, 70–85% quality produces the best balance between file size and visual quality. For web thumbnails or social media previews, 50–60% is usually fine. Experiment until you find the right trade-off for your use case.
Which output format should I choose?
WebP gives the smallest file sizes and is supported by all modern browsers — use it for web images. JPG is the best choice for maximum compatibility with older software and apps. PNG is lossless and best when you need pixel-perfect quality or transparency.
Does it work on mobile?
Yes. The tool works in any modern browser on any device — no app or download needed.
