# How Draftable redlines comparisons involving PDF files

> Understand PDF redline results, supported document combinations, profile settings and what to send support if a result looks wrong.

*Available from version 26.10.0*

Draftable Legal uses a new comparison engine when you select **Redline in Draftable** or **Redline in Word** to compare a Word `.docx` file with a PDF, in either order, or two PDFs. Comparisons that involve older Word `.doc` or macro-enabled `.docm` files continue to use the previous engine, and so do **Word-to-Word** comparisons.

## What changes in your results

The new engine matches text by content, reducing false blocks of deleted and inserted text caused by layout differences, such as a table in one document appearing as paragraphs in the other. When you compare a Word `.docx` file with a PDF, Draftable keeps the Word document's structure for the output.

It handles moved text, tables, headers and footers, footnotes, comments, text boxes and images. It also recognizes visually identical images that have been re-encoded, reducing false image changes.

Results can look different from earlier versions even when you compare the same two documents. PDF-to-PDF results can still contain small fragments shown as separate deletions and insertions, particularly around tables.

## How redline profile options apply

For these `.docx`-to-PDF and PDF-to-PDF redlines, these redline profile options behave differently:

| Option | Behavior for these comparisons |
| :- | :- |
| **Tables** (Compare tables) | Tables are always compared. |
| **Compare at** (previously Comparison resolution) | Comparison is always at character level. |
| `DetectMovesIntoLargerEdits` (profile JSON setting) | This setting is not applied. The separate **Detect moved text** setting still controls move detection. |

Style changes are not compared, and there is no separate cover-page comparison. Numbering and tables of contents are compared as visible text rather than as structured document elements.

See [Redline comparison settings](/hc/en-us/articles/16549612535705-Redline-comparison-settings) for the profile controls.

## If a result looks wrong

Send [Draftable Support](mailto:support@draftable.com) both input documents, a short description of the unexpected result and your error-logs ZIP file.

<Steps>
  <Step title="Export your error logs">
    Open **Settings > Help & Troubleshooting** and select **Export error logs**. Save the ZIP file.
  </Step>

  <Step title="Describe the problem">
    Identify the affected page or clause and explain what you expected to see. Include this description with both documents and the error-logs ZIP so Support can investigate the same comparison.
