Link page references in a six-page booklet
A screenshot walkthrough with fictional practice data. Select a step to explore.
1. Start with
Link page references in a six-page booklet
The fictional balcony herb PDF contains seven “see page” references.
Sample files and contents
examples/bifrosta/balcony-herb-handbook.pdf: a fictional 6-page text PDF, numbered 1–6 in the footer, with seven “see page N” references. One of them points to page 9, which does not exist.
Practice files and guides are free. The complete app is included only where the product page says so.
2. In the app
Try it in three steps
- Load the PDF and find candidate page references.
- Apply the zero-offset calibration and approve six valid candidates.
- Save the linked PDF and inspect its first page.
Show every click and setting
- Open your local Bifrosta page, click Choose a PDF… and select balcony-herb-handbook.pdf.
- Keep the default reference text “see page ” and click Find candidates.
- The calibration step suggests offset 0 (6 of 6 page numbers agree). Click Apply, then Review 7 candidates.
- Click Approve 6 unambiguous, then Continue to export (6 links ready).
- Click Save balcony-herb-handbook.bifrosta.pdf, and optionally Save review job (balcony-herb-handbook.bifrosta.json).
3. The result
Inspect the result
The six-page PDF has six clickable internal links. Its out-of-range page-9 reference stays blocked.
What to check in the practice result
Bifrosta reports “7 candidate reference(s) found”, with 1 blocked: “see page 9” is out of range. Your browser downloads balcony-herb-handbook.bifrosta.pdf, which has the same 6 pages and 6 clickable links. For example, “see page 4” on page 1 opens page 4. The status line shows “6 link annotation(s) written”.
The screen and downloaded PDF come from the same six-page fictional herb booklet. Six links were exported; the invalid page-9 reference was excluded.
What it helps you do
Find literal page references in a text PDF, review the destinations, and export a separate PDF with clickable internal links.
