Compare PDFs runs entirely in this browser tab. The PDF is read from your device, processed here, and saved back to your device. It is not uploaded, and LittleOrMore never receives it. How privacy works
Questions
Are my files uploaded?
No. Both PDFs are rendered and compared in this browser tab.
Does a highlighted area mean the meaning changed?
Not necessarily. Highlights show pixels that differ — fonts, spacing or images can differ without the content changing.
Why does the text comparison look out of order?
Text is extracted in the order it is stored in the file, which can differ from reading order in complex layouts.
