Line Diff vs Word Diff vs Character Diff

Line diff is the fastest view — it shows which entire lines changed. Best for comparing code files, config files, and structured documents where changes happen line by line.

Word diff highlights individual words that changed within a line. Best for prose documents, contracts, and essays where the changes are scattered within sentences rather than on whole lines.

Character diff catches every single character change — a renamed variable, a changed digit, a different punctuation mark. Best for catching subtle edits that word-level comparison might miss.

Why Privacy Matters for Document Comparison

Documents being compared are often sensitive — contracts under negotiation, unpublished manuscripts, internal policy drafts, source code. Most online diff tools send your text to their servers for processing.

Wrklyst text compare runs the entire diff algorithm in your browser tab. Neither version of your document ever leaves your device. Safe for confidential contracts, proprietary code, and private correspondence.

Text Compare vs Microsoft Word Track Changes

Word Track Changes only works if both parties use Word and the original author remembered to enable tracking before editing. Wrklyst text compare works on any two pieces of text from any source — PDFs converted to text, emails, Google Docs exports, or plain text files — with no prior setup required.

Frequently Asked Questions

How do I compare two documents online for free?

Paste the original text in the left panel and the revised text in the right panel at wrklyst.com/tools/text-compare. Differences highlight instantly — no submit button, no waiting, no account needed.

Can I compare Word documents?

Yes — upload .docx files directly and the tool extracts the text for comparison. You can also copy and paste text from any Word document.

Is my text private when I compare documents?

Yes — the comparison runs entirely in your browser. Your text is never sent to any server, never stored, and never seen by anyone. Safe for contracts, source code, and confidential documents.

What is the similarity percentage?

The similarity score shows what percentage of the two texts match. 100% means identical. 0% means completely different. It gives a quick sense of how much changed before reading the detailed diff.

Can I compare more than two texts?

The tool compares two texts at a time. For multi-version comparison, compare version 1 vs 2, then version 2 vs 3 separately.
