How to use this tool

  1. Upload your image with "Choose Image".
  2. Pick the social platform preset, fit mode, and output format.
  3. Click "Resize & Download" — the resized image saves directly to your device.

Fit modes explained

Cover — scales and centre-crops to fill the exact dimensions (no borders). Contain — scales to fit without cropping; fills empty areas with the background colour. Stretch — ignores the aspect ratio and fills every pixel.

Why it's private

All resizing uses the HTML Canvas API in your browser. Your image never leaves your device.
