Prepare a portal-ready PDF with a clear filename and enough margin below the destination size limit. Start with the destination requirements, work from a copy, and inspect the downloaded result. The portal may also check encryption, page count, filename, or PDF version. This keeps the workflow reversible and gives you a concrete final file to review before the next step.

Prepare the client portal PDF before processing

Prepare a portal-ready PDF with a clear filename and enough margin below the destination size limit. Record the source filename, size, page count, and any destination rules first. PDFStay's normal client portal PDF workflow is designed to process the PDF in the current browser session rather than upload it to PDFStay servers. Your own organization or destination policy remains the final authority.1, 2

Verify the downloaded output

  1. Create a working copy of the client portal PDF.
  2. Run the task in PDFStay using the /compress-pdf workflow.
  3. Download the result with a distinct, descriptive filename.
  4. Open the exact output and the portal may also check encryption, page count, filename, or pdf version.

FAQ

Why can a client portal reject a small PDF?

The portal may also check encryption, page count, filename, or PDF version. Keep the source until the final recipient, portal, or reviewer has accepted the output.

Does PDFStay guarantee that every client portal PDF will be accepted?

No. PDF behavior depends on the source file, browser memory, document features, and the destination system. Follow the destination instructions and verify the exact output.
