How to resize an image to exact dimensions

Resize photos by pixel dimensions or percentage and understand fit versus fill.

Websites and forms often ask for images with specific pixel dimensions. Resizing changes the image's pixel width and height; it is different from changing print resolution or file format.

Step-by-step instructions

Open the image resizer and select your image.
Enter a width and height, choose a preset or set a resize percentage.
Use Fit to keep the full image visible, or Fill to cover the dimensions and crop overflow.
Choose an output format, process the image and confirm the displayed dimensions.

Helpful tips

Keep the aspect ratio to avoid stretching faces and objects.
Upscaling cannot recreate detail that was not in the original image.
Fill mode crops overflow, so check the preview before downloading.
