Frequently Asked Questions

Do I need to convert my PDF to Word format first?

No. That is the entire point. The AI extracts text and layout information directly from the PDF layer and aligns it with the Word document’s paragraph structure. You skip the error-prone PDF-to-DOCX conversion step entirely.

How does cross-format text alignment work between PDF and DOCX?

The AI maps text coordinates from the PDF (using spatial positioning) and logically matches them to the DOCX paragraph flow. Tables, headers, and body text are aligned section by section, so a paragraph in the PDF corresponds to the correct paragraph in the Word file—even if page breaks shift.

Also need to compare invoices or scanned receipts?

For financial documents like invoices or receipts where you have a phone photo and a system PDF, try our Image to PDF Comparison tool. It is optimized for tabular data and can strip watermarks before comparing figures.

What if the PDF and Word document have different page counts?

The AI performs content-based alignment, not page-based alignment. It matches paragraphs and sections by their text content and spatial position, regardless of how page breaks differ between the two formats. A 5-page PDF can be accurately compared against a 10-page Word file.

Can I use this for multi-language document comparison?

Yes. The comparison engine supports Chinese, Japanese, Korean, English, French, German, Spanish, Russian, and Portuguese text. Mixed-language documents are handled accurately — each text block is compared in its detected language.
