Questions about Compare PDF files
Are my files uploaded?
This tool processes files in your browser. File contents are not uploaded to FileToast. Downloads stay wherever you save them.
Does comparison detect every visual difference?
No. It displays rendered pages side by side and compares extracted text. Image-only changes require visual inspection.
Can I compare two scanned PDFs?
You can inspect their rendered pages, but the text comparison needs selectable text and does not perform OCR.
What are the file and processing limits?
Up to 50 MB per file, 20 files and 100 MB total. Large or complex files can exceed your device’s or the converter’s capacity. Choose exactly two PDFs. Previews show the first 12 pages of each. Text comparison does not detect all visual or layout differences; scanned pages require OCR.
