Image Resizer — frequently asked questions

How do I resize without distorting the image?

Keep the aspect-ratio lock enabled. When it is on, changing the width updates the height automatically in proportion, so the image keeps its original shape and never looks stretched.

Can I make an image larger?

Yes, you can scale an image up by entering bigger dimensions. Keep in mind that enlarging a photo beyond its original size can make it look softer, since no new detail can be added.

Is there a limit on image size?

There is no fixed cap. Because the resizer runs entirely in your browser and your images are never uploaded, performance depends on your own device, so very large files may take a moment to process.
