Resize images to any size

Private: your files never leave your device.

Frequently asked questions
How do I resize an image without distorting it?
Keep “Keep aspect ratio” turned on. Enter just the width (or height) and Toola calculates the other side automatically.
What happens when I resize several images at once?
In pixel mode, each image is scaled to fit your width and height while keeping its own proportions. In percentage mode, every image is scaled by the same percentage.
Will resizing reduce the file size?
Making an image smaller in pixels almost always makes the file smaller too. For even smaller files, run the result through the image compressor.
Are my images uploaded to a server?
No. Resizing happens in your browser using your device’s graphics engine. Nothing is uploaded.
