Compare Documents

What is Compare Documents?

The Compare Documents tool shows you exactly what changed between two versions of a document. It highlights additions, deletions, and modifications line by line, making it easy to spot every difference at a glance.

Why Would You Need to Compare Documents?

Comparing documents is essential when tracking changes. Here are common situations:

• Contract review: Spot changes between the original and revised contract versions
• Code review: See what changed in code files before or after edits
• Document revisions: Track edits made by colleagues or clients
• Version control: Compare old and new versions of any document
• Quality assurance: Verify that only intended changes were made
• Legal compliance: Ensure document modifications are properly tracked

How to Compare Documents - Step by Step

1. Upload the original: Select or drag the first document (the original or older version)
2. Upload the modified: Select or drag the second document (the new or changed version)
3. Choose options: Optionally enable "ignore case" or "ignore whitespace" for flexible comparison
4. Click Compare: Press the Compare button to analyze both documents
5. Review differences: See additions highlighted in green and deletions in red

Tips for Best Results

• For contracts and legal documents, keep both options unchecked for precise comparison
• For code files, enable "ignore whitespace" to focus on actual code changes
• Use "ignore case" when comparing text where capitalization doesn't matter
• The original file should be uploaded first, the modified file second
• For very large documents, comparison may take a few extra seconds

Frequently Asked Questions

Can I compare files in different formats?

Yes, you can compare a PDF with a Word document, for example. The tool extracts text from both files and compares the content.

What do the colors mean?

Green highlighting shows text that was added in the second document. Red highlighting shows text that was removed from the first document.

Can I compare images or scanned documents?

No, this tool compares text content only. Scanned PDFs without text layers cannot be compared - only PDFs with actual text work.

Is there a file size limit?

Each file can be up to 10MB. For larger documents, consider splitting them into smaller sections.

Will formatting differences be shown?

No, only text content is compared. Font changes, colors, and layout modifications are not detected - the focus is on actual text differences.
