Comparison

Prepta vs Acrobat Preflight

Short answer

Acrobat Preflight is an operator-centric PDF inspection tool in Acrobat Pro. Prepta is prepress automation for print shops: profile-based checks, safe automatic repair, and human review. Use the free Prepta checker to diagnose a single PDF in the browser; use full Prepta when you want repair and validated output at shop scale.

Acrobat Preflight is a powerful operator tool inside Acrobat Pro. Prepta is built for print shops that receive customer files all day — classify, check against your profile, repair what is safe, and escalate the rest. Start with the free browser check when you just need to know what is wrong.

Common questions

Is Prepta a replacement for Acrobat Preflight?

Not as a desktop operator console. Prepta replaces repetitive intake checking and safe repairs for print shops. Many teams still keep Acrobat for edge-case inspection.

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.
