How to use Image Compressor

Compressing images speeds up websites, fits files into upload limits, and saves storage. ToolHub compresses images entirely in your browser so originals never leave your device.

  1. 01

    Choose an image (JPG, PNG, or WebP).

  2. 02

    Adjust the quality slider — 70-80% is a great default for the web.

  3. 03

    Click 'Compress' and wait for the new file to be generated.

  4. 04

    Download the optimized image with a single click.

Pro tips

  • PNG photos shrink dramatically after compression — try it on screenshots too.
  • For social media uploads, 1080px width with 75% quality is ideal.

Frequently asked questions

Does compression ruin quality?+

Slightly — but at 70-80% the change is invisible to the eye while the file is far smaller.

Can I compress in bulk?+

Repeat the process for each image; they all run locally so it's fast.
