Guide & FAQ

How to use · Resize images

Make a mixed batch fit a maximum pixel size, without stretching images or enlarging smaller originals.

Back to workspace ↑
  1. 01

    Add the images

    Choose JPG, PNG or WebP files and check their original pixel dimensions.

  2. 02

    Set the maximum edge

    Enter a whole number from 0 to 6000. The longer side is limited to that value; the other side follows proportionally.

  3. 03

    Check the dimensions

    Preview each result, then download the resized images or a ZIP.

EXAMPLE · NOT YOUR FILES

A simple example

At a 1200 px maximum edge, a 2400 × 1600 image becomes 1200 × 800. A 720 × 960 image stays 720 × 960 because the tool never upscales.

Before you start

  • Up to 20 images; 15 MB per file, 60 MB total and 24 megapixels per image.
  • Longest edge: 0–6000 whole pixels. 0 keeps the original dimensions unless crop or rotation is also enabled.
  • This is proportional longest-edge resizing, not an exact width-and-height or print-DPI tool.
  • Files are re-encoded in the chosen output format. Quality, transparency and metadata behavior follow that format.

A few useful answers

Can I enter an exact width and height?

This version takes one maximum-edge value. It keeps proportions rather than stretching to a fixed rectangle.

Will a small image be enlarged?

No. A 720 × 960 image with a 1200 px maximum edge keeps its pixel dimensions. Re-encoding can still change its file size and metadata.

Does 1200 mean width or height?

It means the longer side. For landscape images that is usually width; for portrait images it is usually height.

Can I change the print DPI?

No. The tool changes pixel dimensions. It is not a print layout or DPI metadata editor.
