PDFsam Reports an Invalid PDF is best approached as a local PDF workflow. In PDFsam Basic, choose the relevant module before selecting source documents. Back up important PDFs and verify the completed result, rather than assuming an operation succeeded because the application closed its progress indicator.
Step-by-step instructions
- Test the PDF in a second reader.
- Try a different known-good PDF with the same PDFsam module.
- Update PDFsam Basic and check its release notes.
- If you have permission, recreate the PDF from the source application and retry.
Example and expected result
For the task pdfsam reports an invalid pdf, start with a duplicate of a small, nonconfidential PDF. Follow the steps using a separate destination path, then open the saved output in your usual PDF reader. Confirm the count and order of pages, the readability of the document, and that the original is still intact.
Important checks and limitations
If you need to change the words inside a PDF page, add OCR, or compress scanned image data, do not assume those features exist in PDFsam Basic. Compare the separate Visual and Enhanced editions before selecting a product.
