Preserve pixel dimensions and readable text

The maximum edge is not always the width

The longer edge is capped and the other edge is scaled proportionally, rounded to a whole pixel. A 4,000 × 3,000 image becomes 1,920 × 1,440 at the first stage with a 1,920 maximum edge. A portrait image becomes 1,440 × 1,920. Smaller originals are not enlarged.

A byte limit may trigger more resizing

In the default mode, dimensions can shrink further if the file still cannot fit the byte target. Entering 1,920 does not promise a 1,920-pixel output. The dimensions on the result card are the final values, and a separate notice appears when pixels were reduced.

The keep-dimensions option preserves the size after applying the maximum edge. JPEG and WebP try quality settings at that size; PNG is encoded at that size. A result that cannot meet the limit remains visible with an over-target status and exact bytes. This option preserves the post-resize dimensions, not necessarily the original dimensions.

Inspect legibility at natural size

Preview thumbnails fit into a small space and can conceal or exaggerate readability problems. Open the original and result separately and compare at the same zoom. Start with small numbers, thin lines and colored text edges.

The sample includes text at 16, 24, 36 and 48 pixels to illustrate how small text reacts to resizing. It does not represent every font, language or document. Check the important parts of your actual submission.

Requirements this tool cannot validate

This tool does not validate identity-photo composition, background rules, print quality, DPI metadata or OCR accuracy. Pixel dimensions and physical print size are different concepts. For printing or regulated submissions, check the receiving institution’s rules and your editor’s output settings.
