How it works

  1. 1

    Upload scanned PDFs over HTTPS

    TLS protects image-heavy files in transit to our secure PDF merger endpoints.

  2. 2

    Quality-preserving join

    We concatenate pages without recompressing scans — merge scanned PDF files without turning text into mush.

  3. 3

    Instant download & purge

    Merge PDF instantly for typical batches. Files auto-delete — zero long-term retention of sensitive records.

Use cases

Medical record compilations

Clinics combine scanned documents into one PDF for referrals while minimizing retention risk.

Court exhibit binders

Paralegals merge scanned PDF files from discovery without downsampling exhibit clarity.

Insurance claim packets

Adjusters join photo-scan PDFs with merge PDF while keeping quality for adjuster review.

Problems we solve

Aggressive compression on merge

Cheap tools re-encode scans as low-res JPEG. We preserve original scan fidelity page by page.

Indefinite cloud storage

Our secure PDF merger deletes inputs and outputs after download by design.

Slow “secure” desktop apps

Get encryption and merge PDF instantly in the browser — no opaque plugins.

Trust & privacy

Zero data retention

We do not archive scanned medical or legal PDFs.

No training on your files

Documents are processed for merge only — never used for AI training.

VPS for huge scan sets

Oversized scanned archives route to Hetzner for stable memory handling.
