Prepare a presentation export that fits the destination limit while keeping charts and labels readable. Start with the destination requirements, work from a copy, and inspect the downloaded result. Large screenshots, embedded photos, and repeated slide backgrounds often dominate the file size. This keeps the workflow reversible and gives you a concrete final file to review before the next step.

Prepare the presentation PDF before processing

Prepare a presentation export that fits the destination limit while keeping charts and labels readable. Record the source filename, size, page count, and any destination rules first. PDFStay's normal presentation 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

FAQ

Why do presentation PDFs stay large?

Large screenshots, embedded photos, and repeated slide backgrounds often dominate the file size. Keep the source until the final recipient, portal, or reviewer has accepted the output.

Does PDFStay guarantee that every presentation 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.
