How to Resize an Image Without Stretching or Distortion

Resize a photo for the dimensions you need

If a website asks for a width of 1200 pixels, enter 1200 in the width field and keep the aspect ratio locked to calculate a matching height. To make both dimensions smaller together, use the percentage control.

Pixel dimensions and file size are different. This tool changes width and height; export format and quality also affect the download size. Use Image Compressor if your main requirement is a smaller file.

How It Works

The image resizer reads the selected picture in your browser and calculates the requested dimensions. It draws a resized version on a canvas, applying the selected format and quality settings when exporting. The preview lets you inspect the result before downloading.
