When developer velocity, AI, and security decide the deal, modern teams pick Nutrient. Below you’ll find the 2025 head‑to‑head: what’s equal, where Apryse holds niche edges, and why Nutrient delivers compounding ROI.
| Nutrient | Apryse | |
|---|---|---|
| | Nutrient builds forward — with an AI-native, JSON-first
platform that’s cloud-ready by default and built for developers who
need to move fast without accumulating tech debt. | Apryse, by contrast, builds around — relying on a
legacy foundation extended through acquisitions, wrappers, and XML-based
tooling that slows innovation and adds complexity. |
| Core architecture | Unified, modern codebase, continuously improved since 2011. | Legacy core from 1998, layered with complexity from multiple
acquisitions. |

Protect your customers and organization with a PDF SDK that’s built on PDFium, the same secure PDF engine battle tested in Chromium and maintained by Google. With SOC 2-compliant processes and a flawless 10-year track record of zero security vulnerabilities or exposures, Nutrient is the PDF SDK that organizations trust — from enterprises to government agencies, and startups.
| Nutrient | Apryse | |
|---|---|---|
| PDF engine | Optimized and well-maintained fork of PDFium (open source,
peer‑reviewed) | Proprietary, closed source |
| Known CVEs | 0 | 12 public CVEs (2018–2025) |
| SOC 2 Type II | | |
| Independent penetration testing | Annual | |
The Nutrient core SDK and user interface sit on top of an optimized fork of PDFium — the same PDF engine used in Chromium, Android, and countless other applications by 2 billion users to open trillions of PDFs every year.
| PDFium PDF Engine | Apryse | |

| Nutrient | Apryse | Winner | |
|---|---|---|---|
| PDF viewing and rendering | Best-in-class performance and fidelity | Reliable | Draw |
| Multi-tab and side-by-side view | Available, not optimized | Built-in with shared resources — optimized, but only critical for
high-tab volume use cases | Apryse |
| UI customization | Basic; new API coming soon | Modular + open source fork — flexible but demands ongoing
maintenance and upgrade costs | Draw |
| Real-time collaboration | Built-in, seamless across SDKs | Requires manual server setup | Nutrient |
| Annotation status workflows | Coming Q4 2025 | Standard support — useful for sequential reviews, but Nutrient
leads in real-time collaboration | Apryse |
| Annotation attachments | Supported, fewer layout options | Rearranging and tab opening | Draw |
| PDF content editing | Faster, smoother UX across platforms | More feature-rich but laggy UX | Nutrient |
| DOCX document authoring | JSON-based, AI-enhanced, light-weight | XML-based, collaborative modes | Draw |
| Spreadsheet editing | Not yet | Viewer available, not editing | Apryse |
| Measurement tools | Parity confirmed | Parity confirmed | Draw |
| Pattern-based redaction | Advanced rules/templates via GDPicture | Not available | Nutrient |
| AI redaction | Unique: natural-language driven | Good with digital documents only | Nutrient |
| Table extraction (including OCR) | Robust OCR and layout logic | Supported — visual-only; Nutrient prioritizes full table
extraction over detection. | Nutrient |
| Table detection (bounding boxes) | Not supported | Claimed AI, unconfirmed — only for born-digital documents,
limited use in real-world workflows | Apryse |
| Form field detection (AI-based) | Not supported | Claimed AI, unconfirmed — only for born-digital documents,
limited use in real-world workflows | Apryse |
| AI data extraction | GenAI, multi-format, prompt-based | Not available | Nutrient |
| Text comparison | Interactive diff + AI summary + jump-to | No sidebar, limited interactivity | Nutrient |
| AI-powered comparison | Unique in market | Not available | Nutrient |
| XFA support (legacy forms) | Not supported | Supported — legacy-only format with limited tool compatibility;
best to migrate | Apryse |
| Rich media (audio/video annotation) | Not supported | Supported — niche use case for multimedia workflows, not needed
in most B2B stacks | Apryse |
| Annotation format (Instant JSON) | Human-readable, AI-friendly | XFDF/XML-based | Nutrient |
