How to Resize an Image Online Free
An image at the wrong size either looks stretched, wastes bandwidth, or gets rejected by the site you are uploading to. This guide shows how to resize an image to exact dimensions — or crop out just the part you need — for free, in your browser. Use the free resize image tool below to resize your image in seconds.
How to Resize an Image — step by step
- Choose an image file.
- Choose Resize to scale the whole image, or Crop to keep only part of it.
- Set the quality slider to balance size and detail.
- Download the finished image.
Tips
- Use the lock icon to keep the original aspect ratio, so the image does not stretch.
- Enlarging a small image cannot add detail — resize down from a larger original for the best quality.
- To crop, drag a rectangle on the image, then drag inside the box to move it or a corner handle to resize it.
Frequently asked questions
Does resizing keep the aspect ratio?
Only if you change width and height proportionally. Enter both values to set an exact size.
Can I enlarge a small image?
Yes, by entering larger dimensions, but enlarging cannot add detail that was not in the original, so the result will look softer than a photo taken at that size. For best quality, resize down from a larger original rather than up from a small one.
Is there a crop selection box on this page?
Yes. Open the Crop tab, drag a rectangle on the image to select the area, then fine-tune it: drag inside the box to move it, or drag a corner or edge handle to resize it, and download the cropped image.
