About this tool
Resizing changes an image's pixel dimensions — to fit a layout, meet an upload requirement or cut the file size. Keeping the aspect ratio locked prevents the image from looking stretched.
It runs in your browser on a canvas, so nothing is uploaded.
How to use it
- Add an image — its current dimensions are shown.
- Type a new width or height.
- Keep the lock on to preserve the aspect ratio, or turn it off to set both freely.
- Resize and download.
Common problems
- The image looks stretched.
- Turn the aspect-ratio lock back on so width and height scale together.
