Worth knowing before you stay or go: The earlier recorded GBP 138 per year figure is not on the current rendered pricing page. The page currently lists Nitro PDF Standard at USD 15 per user per month, billed annually at USD 180.00, and Nitro PDF Classic at USD 270.00 per licence billed once for a three-year Windows term, with Plus being quote-only; no GBP price is shown, so this record leaves priceFromGbp null and does not convert the USD amounts. There is a 14-day free trial and no permanent free tier. The direct-checkout seller is Nitro Software Ecomm Limited, First Floor, 80 Harcourt Street, Dublin 2, D02F449, Ireland, acting as an Authorized Reseller to Nitro Software Inc.; the Ecommerce Terms say Nitro, not Nitro Ecomm, provides and operates the services. The macOS and iOS App Store listings independently name Nitro Software, Inc. as the seller, so the direct-checkout and app-store seller surfaces are separate and are not conflated. The owner/controller remains Nitro Software, Inc., and the USD list prices are attributed to the direct-checkout surface rather than to the App Store listings. The product marketed as Nitro PDF Pro is now sold as the Standard, Plus and Classic tiers rather than under a PDF Pro tier name, and Classic is a three-year Windows term licence rather than a perpetual or monthly plan. Digital signatures in Nitro PDF Pro use a digital ID or certificate and the Windows user guide says the signature confirms the document has not changed since signing and that Nitro restricts some actions to preserve that state; the vendor does not publish a certificate-authority issuance, trust-validation or trusted-timestamp guarantee, and this record makes none. Nitro Sign is a separate e-signing service with its own plans and cloud processing, and bulk e-signing, Smart Redact, Nitro Automate and the AI document tools are separate products rather than features of the installed editor. Editing existing text, images and objects, OCR and PDF export are documented in the desktop and iOS user guides and are treated as installed-app features, while Nitro Sign and the AI services are cloud or vendor services. The security guide documents user and owner passwords and 40-bit RC4, 128-bit AES and 256-bit AES encryption levels, but the record makes no reader-enforcement or universal-compatibility guarantee, and the choice of encryption level affects which PDF readers can open the file. No current first-party Nitro or Apryse page read in this audit states an Apryse ownership or acquisition relationship, so the owner is recorded as Nitro Software, Inc. and no Apryse claim is inferred.

The full Nitro PDF Pro record

The short answer

The closest Nitro PDF Pro alternatives in this index are Adobe Acrobat , ABBYY FineReader PDF and Foxit PDF Editor . They share enough of the job to be worth comparing, which is why they are on this page - a shared job tag is a candidate, not a finding that they work the same way. What separates them from Nitro PDF Pro is what they charge and whether your file leaves your machine. Nitro PDF Pro processes some versions on your device and runs others on a server, which the vendor documents, and 2 of the 6 listed have no vendor service in the path .
