How image resizing works
This tool redraws your image onto a canvas at the dimensions you choose, then re-encodes it. Lock the aspect ratio to avoid stretching, or scale by percentage for quick resizing.
- Exact width and height control.
- Optional aspect-ratio lock.
- Private — files never leave your browser.
Is this image resizer free?
Yes, completely free with no sign-up, watermarks or limits.
How do I keep proportions?
Tick "Lock aspect ratio" — changing width auto-updates height and vice versa.
What is the scale field?
Enter a percentage (e.g. 50 for half size, 200 for double). Width and height update automatically.
Are my images uploaded?
No. All processing is local.
