🔗 PDF Link Checker

A Python tool that scans any PDF and validates all email and web hyperlinks. Includes a web UI to run it from your browser — no coding needed to use it.

What it checks

• Missing hyperlinks (text visible but not clickable)
• Wrong link type (email linked to a web URL, or vice versa)
• Broken addresses split across lines
• Partial linking (only half of a split address is linked)
• Wrong link targets (displayed address doesn't match the actual href)

Output

Generates a colour-coded Excel report with columns: PDF_Link | Hyperlink_Text | Page_Numb | Link_Type | Is_Hyperlinked | Is_Valid | Result

How to run

Install dependencies

pip install flask pypdf pdfplumber openpyxl pyngrok qrcode

Run the web UI

python app.py # local only python app.py --lan # share on same WiFi python app.py --public # share public link (anyone, anywhere)
