How to use

  1. 01

    Choose the source image

    Note the original width and height before setting the output dimensions.

  2. 02

    Set a maximum or custom size

    Use the offered size preset or enter dimensions. The image keeps its proportions and is not enlarged beyond the original.

  3. 03

    Confirm the saved dimensions

    Reopen the result and check both its pixel size and file size. Choose compression separately if a strict byte limit is required.

Frequently asked questions

Does resizing crop the image?

No. It fits the full image within the requested bounds while preserving aspect ratio. Use Image Crop to remove edges.

Why is the output smaller than the requested size?

The tool avoids upscaling and also observes output dimension and pixel limits.

Does a width setting guarantee a file size?

No. Pixel dimensions and byte size are different measurements.
