Image Compressor

Summary

Upload a JPEG, PNG, or WebP image, adjust quality, and download the compressed file — no upload to any server.

How it works

1. Drop or select a JPEG, PNG, or WebP image file.
2. Use the quality slider to choose a compression level (1–100).
3. The tool draws the image onto an HTML Canvas and re-encodes it at the chosen quality.
4. A side-by-side preview shows the original and compressed images.
5. Click "Download Compressed Image" to save the output to your device.
