Useful next steps

Edit a PDF: text, images and annotationsEdit PDF text, add images and mark up pages. Review your changes in the easyPDF24 preview before applying them.
Reorder PDF pages into the sequence you needRearrange all pages in one PDF by entering their new order. Keep every page exactly once and check covers, appendices and existing printed numbers.
Extract PDF pages into one separate documentSave selected PDF pages together as a new PDF. Choose individual pages or ranges and keep the original file for the complete document.

Useful for changes in page appearance

A moved logo, changed number or different line break may stand out in the visual comparison. Pages are paired by their position. If one version has extra pages near the beginning, later pairs may no longer correspond. Align the order first when you need to compare a specific section. This makes the marked areas easier to interpret.

A visual report is not a complete content audit

The tool compares rendered page images at up to 1,200 pixels. Very small text differences can be difficult to see, while different font smoothing can itself produce marks. Hidden text, form logic, metadata and the meaning of a change are not checked. Read important amounts and wording directly in the original files as well.

Frequently asked questions

Does every pink area identify a content error?

No. Layout movement and rendering differences can also produce changed pixels.

Does the tool create a combined revised document?

The output is a PDF comparison report. The two original versions remain separate source documents.
