Keep aspect ratio or change the shape
With Keep aspect ratio on, you only need to enter the width or the height and the other side is calculated so the picture is not squashed. Turn it off to get an exact size such as 1080 × 1080. Then choose Crop to fill to trim the edges, Fit inside to add a border, or Stretch.

Frequently asked questions
How do I resize an image without losing quality?
Making an image smaller keeps it sharp; this tool uses high-quality multi-step resampling. Making an image much larger than its original size will look softer, because detail cannot be invented.
Can I resize many images at once?
Yes. Add as many images as you like. With aspect ratio on, each image keeps its own shape and is scaled to the width or height you choose.
How do I resize an image to a specific KB size?
Resize it to smaller pixel dimensions here, then use the Compress Image tool to fine tune the file size with the quality slider.
Are my images uploaded?
No. Your images are processed in your browser and never sent to any server.
