All 26 free PDF tools
Every one of them does the job it is named after. There is no page here for a tool this site cannot perform, which is why the list is shorter than it could be and why nothing on it will waste your time.

Not here on purpose
Four things people look for that this site does not do, and why.
Optical character recognition
Reading printed text from a scan is a solved problem; reading handwriting is not. A plausible guess attached to an exam script is worse than no text at all, so this site does neither rather than doing one badly.
PDF to Word
A faithful conversion has to reconstruct a document structure that the PDF never recorded. The results are consistently poor enough that rebuilding from extracted text is faster. PDF to Text gives you the words.
Password cracking
A properly encrypted PDF is not opened by guessing, by us or by anyone. Unlock PDF requires the password, always. That is a settled position, not a feature waiting to be built.
Watermark removal
A watermark normally states who owns a document or how it may be used. Removing one in order to pass the document on is not something this site helps with.
