What happens when you enter just one value
If you fill in only the width (or only the height) with aspect ratio locked, the other dimension is calculated automatically so the image isn't distorted. If you fill in both with the ratio locked, the image is scaled to fit within those limits without stretching.
Resizing without keeping the aspect ratio
Turning this option off lets you force an exact width and height, which can stretch or squash the image — useful when the destination requires a specific dimension, even if it distorts the original image slightly.
When should you use this tool?

Privacy and processing
Resizing happens in your browser using the Canvas API — the image is never sent to a server.
Frequently asked questions
- Will resizing distort my image?
- Only if you set both width and height without 'maintain aspect ratio'. With it enabled, the image is scaled proportionally.
