Comparing PDFs? Add OCR.

The optional MarginDiff PDF & OCR Add-on recognizes PDF text for document comparison. It requires separate licensing and administrator setup. Check recognized text against the original pages, especially names, numbers, and tables.

Look beyond the redline

Small edits.
Meaningful differences.

Choose which changes to show. From a single word to a table’s structure, MarginDiff helps you review the details. Fields and links are compared as saved, without opening outside content.

1

Text

Insertions, deletions, moves, and edits, with options for case, spaces, tabs, and quotation marks.

2

Formatting

Font family, size, style, colour, highlight, underline colour, character scale and spacing.

3

Paragraphs

Alignment, direction, line spacing, space before and after, indents, tabs, borders, shading, and heading level.

4

Structure

Named styles, list definitions, section and page layout, headers, footers, footnotes, endnotes, and bookmarks.

5

Tables

Inserted and deleted tables, rows and columns, cell content and formatting, merges and splits.

6

Objects

Comments, text boxes, frames, and changes to images saved in the document.

7

Fields

Contents pages, references, numbers, dates, links, mail-merge fields, and formulas, compared as saved.

8

Revisions

Tracked changes already present in the source document, with their author and timestamp.

Handling your documents

Your files.
Your computer.

Know how MarginDiff handles your files and what a saved package contains before sharing it.

Read the privacy guide ↗

Local comparison

Documents and results stay on your computer. Internet access is used for licence activation.

No document code runs

MarginDiff does not run macros, embedded programs, or outside links. Fields are compared as saved.

Protected files are refused

Password-protected or corrupt files are rejected with an explanation.

Packages are not encrypted

A .diffy file can contain both source documents; protect it accordingly.

Beyond documents

A wider view of your work.

MarginDiff Sheets and MarginDiff Presentations updates are still being tested and are not in the latest installers.

1 / Spreadsheets

MarginDiff Sheets

Compare values, formulas, and formatting side by side. Inserted rows and columns stay aligned; moved references are recognised.

Improvements and limits →

2 / Presentations

MarginDiff Presentations

Compare slide content and formatting, including text, shapes, tables, images, notes, and links. Inserted slides stay aligned.

Improvements and limits →

The limits, in public

A useful guide.
A careful review.

MarginDiff does not compare every document feature. Use the result to guide your review, then read the document.

  • MarginDiff does not run macros, perform mail merges, or open embedded programs
  • Images and other content linked from outside the file are not downloaded
  • Equations are compared as whole objects, not as maths
  • Some drawing shapes and pronunciation guides cannot be compared in detail
  • Document passwords are never bypassed
  • Some settings that affect how older documents appear are not compared

One purchase, thoughtful tools

MarginDiff Documents.

One-time purchase for document comparison. Sheets, Presentations, and MarginDiff Scrub are separate products.

Evaluate the full product for a limited period. Saved work stays open afterwards; new comparisons need activation.

Before you begin

A few good questions.

More detail in the User Guide ↗.

Does it need Microsoft Word installed?

No for DOCX and RTF. Some conversions and the optional email feature use Word. PDFs require separately licensed text-recognition software.

Can I compare a document that already has tracked changes in it?

Yes, including the recorded author and time.

Will it find every kind of change?

See the published comparison limits before reviewing your result. Comparison limits →

How is it licensed?
