CBR/CBZ → PDF → one volume

Convert archives to PDF offline (Calibre, etc.), then merge in ExactPDF for a single table of contents friendly file — only for content you have rights to.

OCR before merge?

If search matters on-device, run OCR PDF per chapter, then merge. Huge page counts: merge in batches, then merge the batches.

Frequently asked questions

Can I merge DRM-protected Kindle files?

No — those are not standard PDFs you own. This workflow is for scanner output, lecture notes, and public-domain PDFs you control.

Should I OCR before merging for search?

Run [OCR PDF](/tools/ocr-pdf) per chapter if search matters on-device; then merge for a single searchable volume — all still local.

Huge page count — will merge fail?

You are limited by device RAM, not a vendor cap. Close other tabs, merge in batches, then merge the batches if needed.

Portrait vs landscape scans?

Normalize rotation with [Rotate PDF](/tools/rotate-pdf) before merge so page flow reads naturally.
