Increase pixel dimensions for larger uses

Use this preset when a source image is too small for a larger layout, presentation, listing, or screen.

The tool resamples the existing pixels with Lanczos interpolation. It can produce larger dimensions but cannot recover detail that is absent from the source.

How to enlarge an image

  1. 1

    Add your images

    Select one or more supported image files.

  2. 2

    Review the target size

    The preset targets 3000 px on the longest side. If that requires more than 4× enlargement, the tool stops at the 4× limit.

  3. 3

    Save the enlarged image

    Run the tool, preview the result, and download the PNG output.

Frequently asked questions

Will increase image resolution recreate missing detail?

The tool resamples the existing pixels with Lanczos interpolation. It can produce larger dimensions but cannot recover detail that is absent from the source.

Can I enlarge several images together?

Yes. Add multiple supported files and process them in one batch. The same size rules and 4× limit apply to each image.
