FAQ
Frequently Asked Questions
How do I compare two PDF files?+
Simply drag and drop your two PDF files into the upload area above. Differino will extract the text from both PDFs and show you a side-by-side comparison with all differences highlighted, additions in green, deletions in red, and modifications in yellow.
Is it free to compare PDF files?+
Yes! You get 1 free comparison with no signup required. For more, credit packs start at just €1.99 for 10 comparisons.
What is the maximum PDF file size?+
All users can upload PDFs up to 45MB. This limit is set honestly below the current storage cap.
Are my PDF files kept private?+
Absolutely. Your files are encrypted during transfer (TLS), processed securely, and never shared with third parties. Anonymous uploads are deleted after processing. We are GDPR compliant and do not use tracking cookies.
Can I compare scanned PDFs?+
Differino works best with text-based PDFs. Scanned PDFs (image-only) may have limited text extraction. For best results, use PDFs that contain selectable text.
Can I share the comparison results?+
Yes! After comparing, click the Share button to generate a shareable link. Pro users can add password protection and set custom expiry times.
