An Acrobat Preflight alternative — for the jobs Acrobat never sees

Acrobat Preflight is a hands-on inspector inside a desktop editor. Preflight is automated document QC — API-first checks across five formats, from USPS barcodes to accessibility evidence. Drop a file for a free scorecard, no signup.

PDF · AFP/MO:DCA · PCL · PostScript · IPDS — validated and reported, never edited.

Automated, not manual
REST API, CLI, and CI checks (beta) — QC that runs on every job in a pipeline, not when someone opens a desktop app and remembers the profile.
Beyond PDF
AFP/MO:DCA, PCL, PostScript, and IPDS parse natively — transactional mail formats Acrobat never opens.
Mail compliance
USPS Intelligent Mail barcode validation (USPS-B-3200 FCS round-trip), presort and field checks on AFP.
Standards evidence
PDF/UA-1/-2, WCAG 2.1/2.2, Section 508 & EN 301 549 per-criterion results with explicit not-evaluated states — VPAT-grade honesty, not a green badge.
Regression diff
Every run compared to an approved baseline — template drift becomes findings.
Team visibility
Shared workspaces, webhooks, audit trail — results live where the team works, not inside one operator’s Acrobat.

The honest framing: Acrobat’s preflight engine is genuinely excellent at what it was built for — interactive, single-file PDF inspection beside the editing tools. What it was never built for is the production side: checking every job automatically, in the formats transactional mail actually ships in, with results a team and a compliance reviewer can share. Shops usually keep Acrobat on the designer’s desk and put Preflight in the pipeline.

Frequently asked questions

When is Acrobat Preflight still the right tool?

For a designer or prepress operator interactively inspecting and fixing a single PDF — Acrobat’s preflight (powered by callas technology) is deep, mature, and sits right next to the editing tools. Preflight (ours) is for the automated, every-job, multi-format gate; it validates and reports but never edits.

Doesn’t Acrobat Pro already include preflight?

Yes — and if your whole workflow is one person, one PDF at a time, it may be all you need. The gap appears at production scale: no API, PDF-only, per-desktop, and results trapped in the app. That gap is exactly what Preflight covers.

How does pricing compare?

Acrobat Pro is per-seat subscription pricing (see Adobe’s current rates — bundled with the editor). Preflight has a free anonymous analyzer and team workspaces from $49/mo with compliance modules at $49–79/mo — priced per team and pipeline, not per desktop.

Can Preflight run Acrobat/callas preflight profiles?

No. Preflight ships its own deterministic, spec-traceable rulesets (PDF/X, PDF/A, PDF/UA, USPS and more) with pinnable versions rather than importing profile formats.

Can I try it without installing anything?

Yes — drop a file on the homepage for a free structural scorecard. No signup; anonymous uploads purge within 24 hours.
