PREP (Continual Engine) alternatives for PDF remediation
Short answer: PREP is Continual Engine's PDF remediation platform, typically licensed to institutions such as universities, with pricing by quote. Smaller organizations without a license can use self-service remediation with published prices (PDFAccessly: $0.45 to $0.78 per page, 5 free pages a month), Adobe Acrobat Pro, or manual remediation services from about $4 per page.
What PREP is
PREP is a cloud platform from Continual Engine for remediating PDFs and other documents. Universities such as Virginia Tech provide it to staff through assigned licenses, alongside a quote-based service where files are sent to Continual Engine for remediation. We could not find a published per-page price.
Alternatives
| Option | Pricing | Best for |
|---|---|---|
| PDFAccessly | Published: $0.45 to $0.78/page, 5 free pages/month, no contract | Small governments, schools and libraries with mostly text documents |
| Adobe Acrobat Pro | Subscription | Staff who will fix documents by hand |
| Manual services | Published examples from about $4/page for simple documents | Forms and complex documents |
| Free checkers (PAC, veraPDF) | Free | Finding out which files need work |
What to compare
- Price model. Per page with no contract versus annual license. For a few hundred documents, per page is usually cheaper; for a large university, a license may be.
- What is automated. Alt text, headings, tables, OCR, forms, contrast.
- Validation and reports. Which validator, and do you get a report per file?
- Data handling. Where files are processed, how long they are kept.
Ours: everything is automated except form fields and color contrast; veraPDF validation and a report on every file; files deleted after 7 days.
Frequently asked questions
- How much does PREP cost?
- We could not find published pricing. Review sites list pricing on request, and university pages describe licenses assigned to staff and a quote-based service for files sent to Continual Engine.
- My university has PREP. Should I use something else?
- If your institution provides a PREP license, use it; it costs you nothing extra. Alternatives matter for organizations without a license.
