Image Compressor

The Image Compressor reduces an image’s file size by re-encoding it at a quality you control, showing the before and after sizes as you adjust. It is for anyone trimming photos for the web, email, or upload limits without a desktop editor.

Large images slow pages and bump against upload caps. Compressing in the browser lets you find the smallest acceptable size visually, and the photo is never uploaded to a server.

1. Drop an image onto the tool, or click to choose one from your device.
2. Drag the quality slider and watch the projected file size update live.
3. Compare the preview against the original to judge where quality starts to suffer.
4. Settle on the smallest size that still looks good.
5. Download the compressed image.

• Live quality slider with an instant size readout
• Side-by-side comparison of original and compressed result
• Works on JPG, PNG, and WebP inputs
• Compression done entirely in the browser

• For photographs, JPG or WebP at around 75–85% quality usually balances size and clarity well.
• Compress at the final display dimensions — shrinking a huge image saves far more than quality alone.
• Keep an untouched original; compression is lossy and cannot be fully reversed.
