How this tool works
The image is redrawn on a canvas at the dimensions you set. With the aspect ratio locked, changing one dimension recalculates the other from the original proportions.
Frequently asked questions
- Are my images uploaded?
- No. Resizing happens in your browser.
- Will resizing blur my image?
- Enlarging beyond the original size will look soft. Reducing size stays sharp.
- What does 'lock aspect ratio' do?
- It adjusts the other dimension automatically so the image is not stretched.
