Comparison
Prepta vs Adobe Acrobat Preflight
Short answer
Acrobat Preflight is the preflight tool built into Adobe Acrobat Pro, developed by callas software and part of Acrobat since 2003; a person runs it on the document they have open. Prepta is prepress automation for print shops: every customer file is checked against your production profile, the fixes that profile allows are applied, the result is revalidated, and exceptions go to review.
Acrobat Preflight lives inside Acrobat Pro, and it assumes someone is sitting in front of it. That is the right tool when an operator is already opening the file. It is the wrong shape when forty customer PDFs arrive before lunch and each one needs the same six questions asked of it. Prepta runs those questions against your production profile and only involves an operator where the answer is a judgement call.

|---|---|---|
| Who it is for | Designers and prepress operators working in Acrobat Pro | Print shops receiving customer artwork |

| Workflow | Open the PDF → choose a profile → analyse or fix → save | Upload → classify → preflight → apply permitted fixes → revalidate → review queue |
| Automation model | A person runs a profile on the open document; some profiles include fixups | Every file is processed automatically; the profile's per-rule policy (auto, review, block) decides what may change |
| Manual editing | Acrobat Pro's editing tools are at hand | No interactive editor; repairs are automatic, recorded operations |
| Profiles | Acrobat preflight profiles you select or configure | Your production profiles per workflow; a public profile for the free check |
| Customer intake | Designed around the document you have open | Browser upload, multi-file and ZIP/7z batches on paid plans |
| Review and escalation | The person running Preflight decides | Files that need a decision reach a review queue with the measurement attached; blocked files stop |
| Record of changes | Preflight report for each run | Every change recorded against the preserved original |
| Best first step for one PDF | Open in Acrobat Pro and run Preflight | Free upload at /tools/pdf-preflight-checker — no account |
Choose Adobe Acrobat Preflight when
- You already work in Acrobat Pro and check files one at a time
- You are editing a single file yourself rather than processing a queue
- You rely on Acrobat profiles and fixups you already trust
Choose Prepta when
- Customer files arrive all day and need the same rules every time
- You want safe auto-repair plus a review queue, not only a report
- You want every change recorded against the original
- You want a free shareable report before anyone opens Acrobat
Where Prepta is not a replacement
- Interactive work on a PDF: Prepta has no editor, and it is not a general PDF application.
- Checking a file in the application you are already working in: Acrobat Preflight runs where the document is open.
Using both
The two fit together: Prepta checks and repairs incoming files automatically, and when a file needs hands-on work, the operator opens it in Acrobat Pro — with Prepta's finding and measurement already in hand.
Common questions
Is Prepta an alternative to Acrobat Preflight?
For checking customer files as they arrive, yes: Prepta runs every file against your production profile without anyone opening it, applies the fixes the profile allows and routes the rest to review. As a desktop tool for inspecting and editing one PDF by hand, no — keep Acrobat Pro for that.
Is Acrobat Preflight the same technology as callas pdfToolbox?
Acrobat Preflight is developed by callas software, the company behind pdfToolbox, and has been part of Acrobat Pro since 2003, according to callas. Prepta runs its own preflight engine.
Can I try Prepta without buying Acrobat?
Yes. The free PDF preflight checker runs in the browser: upload a PDF, get a Prepta Score, share the report. No Acrobat licence required.
Does the free check do Acrobat-level PDF/X validation?
No. The free public profile checks PDF/X-4 markers (and colour, bleed, fonts, resolution, transparency). That is an honest early warning, not a claim of full ISO PDF/X validation.
