What is the auto-detect links feature?
Flipsnack makes it easy to automatically detect and hyperlink URLs, email addresses, and phone numbers in your PDFs—saving you time and effort.
The Auto-detect links option automatically finds and hyperlinks any URLs, email addresses, or phone numbers present in your uploaded PDF. This means you no longer have to manually add hyperlinks after uploading your document.
What types of links are detected?
Flipsnack can automatically detect and hyperlink:
Web addresses:
-
www.flipsnack.com
-
http://www.flipsnack.com
-
https://www.flipsnack.com
Email addresses:
- contact@flipsnack.com
Phone numbers:
- +18085037007972
- +44.7975.556677
- +49/1522/34/33/33
- [+40/259/425/273]
- ([+40]259/425/273)
- and many other variations using parentheses, brackets, dots, or slashes.
Note: The examples above are just a few of the supported formats. Many other variations are also recognized automatically.
How to enable Auto-detect links?
Once you have uploaded your PDF file, go to the Customize menu, Appearance tab and check the Auto-detect links option.

Table of contents detection
If you have a PDF file that contains a properly formatted table of contents, Flipsnack will automatically recognize it and the message "We've detected a table of contents in your document. Enable this option to display them in your flipbook widget" will be prompted.
Otherwise, if your PDF either doesn't contain a table of contents or it does but it's not properly formatted, you'll be prompted with this message instead: "We didn't detect a table of contents in your document, so this option is unavailable."
