About this tool
Online forms frequently ask for photos of a fixed size, such as 600×600 for a profile or 413×531 for a passport-style photo. Social networks and websites also look best when images match their recommended dimensions.
With Keep aspect ratio on, changing the width updates the height automatically so the picture is never stretched. Turn it off when a form demands an exact width and height. Resizing uses your browser's high-quality smoothing for clean results.
You can save as JPG, PNG or WebP. Your image is processed locally and never uploaded.
Questions and answers
Can I make an image larger?
Yes, but enlarging cannot add detail that was not there, so big increases may look soft. Reducing size always looks sharp.
What is aspect ratio?
It is the shape of the image: width divided by height. Keeping it locked prevents faces and objects from looking squashed or stretched.
How do I resize to a passport photo size?
Untick Keep aspect ratio and enter the required pixel width and height. Crop your photo first if its shape is very different.
