Frequently asked questions
How do I compare two legal documents online?
Upload both versions — PDF or DOCX — and Compare Files extracts the text locally and highlights every addition, deletion, and edit inline. It works even when the two files are in different formats, so you can diff a PDF against a Word version without converting anything.
Are my documents kept confidential?
Yes. All comparison runs in your browser and nothing is uploaded to any server. Privileged and confidential documents never leave your device, so there is no data-breach exposure and no processing agreement to sign.
Can I compare documents visually as well as by text?
Yes. In addition to the inline text diff, a Page images tab renders each PDF page and shows a pixel-level visual comparison, so reformatting, moved blocks, added stamps, or signature changes are obvious even when the wording is unchanged. Visual page diffs are available for PDFs; DOCX comparison is text-based.
Do I need Microsoft Word or Adobe Acrobat?
No. Compare Files reads PDF and DOCX directly in the browser, so you can compare document versions on any device without installing or licensing Word or Acrobat.
No AI means no hallucinations
Compare Files uses a deterministic, logic-based engine — not a language model. It reports every change that is actually in your files, and never invents one.
Your files never leave your device. Everything runs in your browser — no uploads, nothing stored.
No AI, so no hallucinations. A deterministic engine reports every real change and never invents one.
No upload, no server wait. Comparisons run locally and keep working offline once the page has loaded.
