Downloaded PDF Not Opening? Fixes for Admit Cards & Bills
It's the night before the exam and the admit card you just downloaded won't open. Or the electricity bill, the bank statement, the fee receipt. Before you assume the file is "corrupted", it helps to know that a PDF from a website fails to open for one of a handful of reasons — and most of them aren't corruption at all. Here's how to work out which one you have, and what to do about each.
Find the cause first
| What you see | Likely cause | What to do |
|---|---|---|
| File is 0 KB, or only a few KB | Download stopped early | Download again on a stable connection |
| "Not a supported file" / "damaged", right after logging in to a portal | The site sent an error or "session expired" page, saved as .pdf | Log in again and re-download |
| Viewer asks for a password | Password-protected on purpose (statements, e-Aadhaar) | Enter the password — nothing is broken |
| Phone says "can't open file" or shows no app | No PDF viewer set as default | Open with Chrome or Google Drive |
| Opens with blank pages or errors in every viewer | The file is genuinely damaged | Repair it (below) |
1. The download didn't finish
On mobile data, WhatsApp and email downloads often stop partway, leaving a file with the right name but only part of the contents. Look at the size in your file manager: an admit card or bill of 0 KB, or just a few KB, is incomplete. Delete it and download again, ideally on Wi-Fi, and wait until the download finishes before opening it.
2. It's a web page, not a PDF
This is the classic problem with exam, university and government portals. If your login session has expired — or the server is busy — the site sends back an error or login page instead of your document, and your browser saves it with a .pdf name anyway. No PDF viewer can open it, because there's no PDF inside.
How to check: open the file in Notepad (or any text editor). A real PDF starts with %PDF-. If you see <!DOCTYPE html> or <html>, it's a saved web page. Repair PDF also detects this and says so in plain words.
Fix: log out, log back in to the portal, and download the document again. If the site is overloaded (results day, admit card release), try again after some time.
3. It's password-protected
If your viewer asks for a password, the file isn't broken — it's protected on purpose. Bank statements, some utility bills and the e-Aadhaar are commonly sent this way. The password format is usually explained in the email or SMS that came with the file, or on the provider's website. For e-Aadhaar, it's the first four letters of your name in capitals followed by your year of birth — see our Aadhaar guide.
4. Your phone has no PDF app set
On some Android phones, tapping a PDF shows "can't open file" or a list with no suitable app. Open it with Chrome (drag it in, or use Open with) or with Google Drive's viewer. On iPhone, the Files app opens PDFs directly.
5. The file really is damaged
If the file has a real size, starts with %PDF-, isn't password-protected, and still won't open anywhere, repair it:
- Open Repair PDF and drop in the file.
- Read the diagnosis — it tells you what went wrong and how many pages came back.
- Download the repaired PDF.
These steps run in your browser, so the file isn't uploaded. For badly damaged files there's an optional stronger repair on our server, which only runs if you tick a consent box — don't use it for ID documents. A password-protected file keeps its password after repair; repair can't remove it.
Still won't open? Find out what's wrong and fix it in your browser.
Repair PDF — FreeBefore the next important download
- Download admit cards and results as soon as they're released, not minutes before you need them.
- Open the file once right after downloading, while you're still logged in to the portal.
- Keep a second copy — email it to yourself or save it to Drive.
