The comparison output produced by SimpleFileTools is an aid to document review. It reports differences in the text layer of the PDFs you provide. It is not legal, financial, regulatory or engineering advice, and it does not replace a qualified reviewer's judgement.
Results depend on the quality of the input: scanned documents without a text layer, damaged files and unusual fonts or encodings can produce incomplete comparisons. Always confirm material changes against the source documents before acting on them.
SimpleFileTools is not affiliated with any regulator, government body or the vendors of other document comparison products mentioned on this site.
