Frequently asked questions

Simple answers to your questions

How do I compare two PDF files?
Upload both PDFs and WriteSimpli lines them up side by side, highlighting text that was added, removed or changed.
What kinds of changes will I see?
Text additions, deletions and edits are highlighted. Changes to images or complex layouts may not always be detected.
Can I compare scanned PDFs?
Yes, after the text has been recognized. Results depend on scan quality, so check flagged areas against the originals.
Is this useful for contracts?
Yes. Comparing contract versions helps you catch edits before signing. For legal decisions, have a qualified person review the final document.
