Frequently Asked Questions
How does the text diff work?
The tool extracts text from each page of both PDFs, compares it at word, sentence, or line level, and highlights additions and deletions in side-by-side review panes.
What does the visual diff show?
Visual diff renders both PDF pages as images, highlights changed pixels, reports a visual-change percentage, and supports slider or side-by-side review modes.
Is my PDF uploaded to a server?
No. All processing happens entirely in your browser using JavaScript. Your PDFs never leave your device.
Can I export the comparison?
Yes. You can copy the summary or download a text report with document names, page counts, similarity, and per-page changes.

What to check
- Methodology: extract comparable text, detect additions/deletions, mark changed pages, and support visual review where text extraction is incomplete.
- Verify pages with no extractable text, large layout changes, scanned pages, signatures, tables, and attachments manually before approval.
- Copy the summary or download the review report for internal review without storing source document contents.
Limitations
- Disclaimer: comparison aid only, not legal review, version-control guarantee, official audit, or approval workflow.
- Text extraction can miss changes in images, scans, vector graphics, annotations, fonts, or hidden layers.
- Privacy note: compare sensitive contracts, invoices, HR records, or legal documents locally and share only the minimum review summary needed.
Source/freshness note: verify current client, lender, customs, tax, document, or regulator requirements before relying on generated outputs.
