- Device & OS
- Android
- Scenario
- Navigating between multiple related PDF documents using embedded hyperlinks on a mobile device.
- Observed behavior
- Hyperlinks pointing to local PDF files often fail to open the target document on Android due to OS security, file path formatting, and application sandbox restrictions.
Verify that both the source PDF and the target PDF files are accessible, and be aware that Android's scoped storage heavily restricts apps from launching local file paths directly.
Use Web-Hosted URLs (HTTPS Links)
By hosting the target PDF online, you bypass Android's local file path restrictions, allowing the link to open reliably in a mobile browser or supported viewer.
Android applications operate in isolated sandboxes for security, meaning a relative file path like 'C:/documents/file.pdf' or even a local Android path will not work across different PDF viewer apps.
Replacing local file links with stable web URLs ensures universal compatibility regardless of the device or the specific PDF reader being used.
Upload the secondary PDF document to a reliable cloud storage service, such as Google Drive, Dropbox, or OneDrive.
Change the file's privacy settings to 'Anyone with the link can view' and copy the generated HTTPS URL.
Open your source PDF in a PDF editor on your PC or mobile device. Edit the existing hyperlink and replace the local file path with the copied HTTPS web address, then save the document.
Merge Documents into a Single PDF
Combining the source and target PDFs into one document allows you to use internal page links, which work natively and flawlessly on all Android PDF viewers.

Frequently Asked Questions
Why do functional local PDF links on Windows break on Android?
Windows and Android use entirely different file systems and path structures. A link pointing to a local 'C:\...' drive or a relative folder path on a PC will not correctly map to Android's storage structure, causing the link to fail.
Can I use Google Drive links in my PDF?
Yes. Using a direct Google Drive sharing link inside your PDF is highly reliable on Android. When a user taps the link, their device will either open it in the web browser or directly inside the Google Drive app.
Do internal PDF hyperlinks work on Android?
Yes, internal hyperlinks (links jumping from one page to another within the same PDF document) work perfectly on almost all Android PDF viewers because they do not require external file access permissions.
