Compression runs through browser-image-compression, a library that resizes and re-encodes the file inside a Web Worker - a background thread in this browser tab. The original and compressed files stay in memory on your device; neither one is ever sent to a server.

How to use it

  1. Upload, paste, or drag-and-drop an image.
  2. It compresses automatically at the default quality and shows a before/after size comparison.
  3. Drag the quality slider to trade off file size against image quality - it recompresses live.
  4. Click "Download Compressed Image" to save the result, or "Copy to Clipboard" to paste it straight into another app (clipboard copies are always PNG, matching every other tool here).

Frequently asked questions

Does my image get uploaded to compress it?

No - compression runs through browser-image-compression inside a Web Worker in your browser tab. The original file never leaves your device.

Will compressing change my image's dimensions?

No - width and height stay exactly as uploaded. Only quality and file size change.

What happens when I move the quality slider?

It automatically recompresses your image at the new quality and updates the size comparison, so you can see the trade-off before downloading.

What image formats can I upload?

JPG, PNG, WebP, and other common image formats.

Is there a file size limit?

No hard limit is enforced - everything runs locally, so larger files just take a bit longer to process.

Does it strip EXIF metadata, like GPS location?

Yes - EXIF data (including camera and location info) is dropped by default as part of compression.
