Word Diff
Compare Two Word Documents Online
Compare two Word documents online and see every difference in seconds. Five modes: rich text for in-place changes, plain text for word-level edits, redline for legal markup, image for visual layout checks, and details for file metadata. Works on .doc and .docx with no Microsoft Word needed.
Your documents stay completely private - the entire comparison runs in your browser. Contracts, NDAs, HR letters, and manuscripts never leave your device. The redline export saves as a clean PDF ready to share with counsel or a counterparty.
Five Ways To Compare Word Documents
Pick the mode that matches what you're reviewing. Switch freely without re-uploading.
Rich Text
Changes shown on the rendered pages. Removed text in red, new text in green, edits in yellow. Same look as Word's track changes.
Plain Text
Text from both documents in two columns, differences highlighted word by word. Formatting stripped so you focus on wording.
Redline
New wording underlined in blue, removed wording crossed out in red. One document ready to send to a lawyer or reviewer.
Image
Compares rendered pages visually. Catches font swaps, shifted margins, and moved headers that text extraction would miss.
Details
Page count, word count, file size, author, last modified, document properties - a quick overview before digging in.
Legal Redline Comparison For Contracts
Redline mode produces the exact markup legal reviewers know. New wording underlined in blue, removed wording crossed out in red, all in one document that reads like a marked-up draft.
Saves as a standalone PDF that opens in any reader. The comparison runs entirely on your computer, so confidential drafts and signed agreements never leave your device.
What The Redline Export Includes
- One clean PDF with insertions in blue and deletions crossed out in red
- Summary showing how many insertions, deletions, and edits were found
