Scenario
Sharing or transferring a PDF file to a customer or external recipient.
Observed behavior
The PDF becomes corrupted and cannot be opened only after a particular transfer path is used or the recipient saves the file.
Before you start

Ensure you have access to the original, uncorrupted PDF file and identify the exact email client or file-sharing service used to transfer the document.

Solution 1Recommended

Test File Integrity and Use Alternative Transfer Methods

Compare the corrupted file with the original to isolate transfer issues, and utilize safer delivery methods like direct links.

File corruption often occurs when email gateways or specific transfer protocols alter the file's structure. Comparing the original and corrupted files can confirm if the transfer method is the culprit.

1
Request the corrupted file

Ask the customer to return the corrupted PDF so you can compare its file size and checksum with your original document.

2
Use a direct download link

Upload the original PDF to a secure cloud storage service and share a direct download link with the customer, bypassing email attachments completely.

3
Compress the file before sending

Place the PDF file into a ZIP archive before sending it to protect the document's internal structure from being modified during transit.

Frequently Asked Questions

Why does my PDF get corrupted when sent via email?

Email servers sometimes encode attachments incorrectly or block specific data streams for security purposes, which can alter the file structure and cause corruption upon downloading.

How can I tell if the PDF was corrupted during transfer or if it was already broken?

Check the file size and checksum of your original file against the one the customer downloaded. If they differ, the corruption occurred during the transfer or saving process.

Can compressing a PDF prevent it from getting corrupted?

Yes, placing the PDF inside a ZIP or RAR archive protects its internal file structure from being modified or corrupted by transfer protocols and email clients.

What should the customer do if they cannot open the PDF I sent?

Ask them to update their PDF reader, try opening the file in a standard web browser, or request that you send the file via a secure cloud storage link instead.
