FAQ about PDF comparison

How accurate is the comparison?

The comparison is very useful visually, but it is not the same as a formal technical validation. Findings should always be checked against revision status, scale, and project context.

Why do I see many markers even when little changed?

Common causes are different PDF exports, slight page shifts, changed fonts, or different rasterization. In these cases, robust settings and page-by-page focus help.

Are my documents uploaded?

According to the current functionality, processing runs locally in the browser. For legal details, please review Privacy.

Can I use results for team alignment?

Yes. Exported views are useful for reviews and alignment, but should always include page references and plan references.

Which documents are most suitable?

• Two technically related versions.
• As similar page size and order as possible.
• PDFs without strong compression artifacts.

Which minimum steps improve quality the most?

1. Name files clearly and assign correctly (A old, B new).
2. Start in standard mode and only fine-tune when needed.
3. Close findings with technical review and proper documentation.
