How to Resize an Image in Millimeters

1

Upload Your Image

Click the upload area to select an image from your device or simply drag and drop the file. You can upload JPG, PNG, GIF, BMP, or WEBP images up to 10MB in size.

Set Dimensions in Millimeters

Enter your desired width and height in millimeters. If you want to maintain the original aspect ratio, ensure "Maintain Aspect Ratio" is set to "Yes" - then you only need to enter either width or height, and the other dimension will adjust automatically.

Select Output Format and Quality
