Frequently asked questions
- How does Validate PDF work on MakeOverPDF?
- Check a document for structural and stream errors. MakeOverPDF runs qpdf --check + pdfinfo on the server and returns: A report on this page — nothing is downloaded or stored.
- Is Validate PDF free and private to use?
- Yes. MakeOverPDF requires no user account, watermarks nothing unless you use the watermark tool, and deletes your uploaded document from the private working directory as soon as the request finishes.
- What are the file size and page limits for Validate PDF?
- This is a structural verdict: cross-reference tables, object syntax and stream encoding. A document can pass every one of these checks and still render wrongly on some readers — the tool says so on the result page rather than overclaiming. The full "Information and validation report" tool shows this same check alongside the document's metadata, page geometry and version — reach for it when the question is more than "is it broken". Nothing is stored: the answer appears on this page and is gone after the next navigation.
