Question details
PDF hyperlinks containing accented characters fail to route correctly and return a 404 error page.
- Product
- Device & OS
- not provided
- Scenario
- Clicking an embedded hyperlink in a PDF document to navigate to a specific webpage.
- Observed behavior
- The browser opens a 404 error page instead of the intended destination because it fails to parse the unencoded accented characters passed by the PDF reader.
Ensure you have the exact destination URL and access to a free online URL encoding tool before modifying your PDF document.
Apply URL Encoding to Accented Characters
Manually encode the special characters in your URL to ensure broad compatibility across web servers and browsers.
Standard URLs historically do not support special characters like é, à, è, ü, ö, or ä. While modern web browsers often encode these automatically when typed in the address bar, PDF readers clicking through to a link may pass the raw characters to the server, leading to a 404 error. Converting these characters into a web-safe format using URL encoding resolves the issue.
Locate and copy the exact web address containing the accented characters.
Use an online URL encoding tool (such as the W3Schools URL Encoder) to convert the accented characters into a safe format. For example, 'é' will become '%C3%A9'.
Open your PDF in an editor, right-click the existing broken hyperlink, and select 'Edit Link' or the equivalent property option.
Paste the newly encoded URL into the link address field and save the PDF document.

Frequently Asked Questions
Why do accented characters cause 404 errors specifically in PDF links?
Unlike web browsers that automatically format typed URLs, PDF readers often send the raw accented characters directly to the web server. If the server does not support or expect these raw characters, it fails to locate the correct page, resulting in a 'Page Not Found' (404) error.
What exactly is URL encoding?
URL encoding is a standardized mechanism for translating characters with special meaning, or unsupported characters (like spaces and accents), into a universally accepted format. It replaces the unsafe character with a '%' followed by two hexadecimal digits.
Can I use spaces in my PDF URLs instead of accents?
No, spaces are also not valid in standard URLs and will often cause broken links in PDFs. Spaces should be encoded as '%20' or, ideally, replaced with hyphens in the original web server's file name.
