Merge and compress PDF locally (privacy)

Updated: 2026-07-05

Merge PDF without online services

Combining PDFs is common for reports and scans. Web tools require uploads — Coto does it locally.

Merge steps

  1. Open PDF tools in Coto
  2. Add PDFs in order
  3. Generate single file
  4. Save locally

Compress PDF

Scanned files are heavy. Local compression reduces size for email.

Password protect

Coto can protect PDFs — all offline.
