How to Check a PDF Before Uploading It
Run a short preflight so the file you choose is the right file, not merely a file that opens.
Last updated
Before uploading a PDF, confirm the destination's size, extension, page, naming, and privacy requirements. Open the exact file you plan to select, check page count and order, read important text, test required links or fields, and inspect for accidental extra pages. If you make a change, save a new version and repeat the preflight before uploading it.
Check the file and the destination together
A PDF can be healthy but still wrong for a particular form. Start with the destination's instructions, then inspect the exact local file. PDFStay's ordinary compression is designed for the current browser session, which can help prepare a copy, but it cannot see a portal's private validation rules.1, 2
| Area | Question | Action |
|---|---|---|
| File identity | Is this the final intended copy? | Check path, name, size, and modified time |
| Content | Is every required detail present? | Read pages and test required features |
Upload only after the preflight passes
- Read the destination rules and note any size margin.
- Open the exact local file and inspect it.
- Make changes in a new version if needed.
- Select that verified version and save the confirmation.

What should I check besides file size?
