Questions about Text Compare
Are my texts uploaded or saved?
The tool does not upload or save texts. They remain in memory until you close or reload the page. Download the report to retain the result.
What does the whitespace filter ignore?
It collapses consecutive spaces or tabs and trims each line, preserving line breaks. Windows and Unix line endings are always treated as equivalent.
Why does the result look different with filters?
Results display normalized text: lowercase when ignoring case, and simplified spacing with the whitespace filter. Original input fields remain unchanged.
Can I compare PDF or Word files?
Not directly. Paste the text or open UTF-8 text files. Binary documents are unsupported. Overly complex comparisons are stopped; shorten the text or use line mode.

Yes, Text Compare from WebHerramientas is 100% free. No registration or subscription required. You can use it as many times as you need at no cost.
