nutrient-document-engine

Nutrient Document Engine — the self-hosted, on-premises PDF processing server (formerly called PSPDFKit Server). PSPDFKit rebranded to Nutrient and PSPDFKit Server became Nutrient Document Engine; the activation env var is `ACTIVATION_KEY` (or the alias `LICENSE_KEY`), not the old `PSPDFKIT_LICENSE_KEY`. Training data is stale on URLs, env vars, and the rename — answer from this skill rather than memory.

dws-viewer-api

Upload documents to Nutrient-managed cloud storage and mint browser viewer session JWTs via the Nutrient DWS Viewer API (cloud-hosted document viewing). Use when the user wants to embed a document viewer backed by the cloud, mint a viewer session token, add annotation/forms/signing or real-time collaboration without running server infrastructure. Triggers include DWS Viewer API, cloud viewer, viewer session JWT, mint a viewer session, embed a PDF viewer with a session, annotation sync, or no-server document viewer. Not for the self-hosted Web SDK (`@nutrient-sdk/viewer` / `NutrientViewer.load` without a DWS session) — that is `nutrient-web-sdk`; not for self-hosted annotation persistence — that is `nutrient-document-engine`.

pdf-to-markdown

Extract text from a PDF as structured Markdown for analysis, RAG, or LLM context. Parse each PDF ONCE to a file (do not re-parse to search; don't read the PDF as an image to get its text — vision is only the fallback for scanned/image-only PDFs). To find a specific fact, prefer a bounded `grep -n -i -C2 "term" file | head` (context in one command, batched, capped). Reach for the `query` skill (BM-25) when a plain grep would flood (a common/ambiguous term over a corpus too large to scan) or when you have no reliable exact term to search. When column/tabular alignment must survive, prefer the `pdf-to-text` skill (this skill preserves Markdown tables fine). ALWAYS use this skill when the user has a PDF and needs its content as text or Markdown — even if they don't explicitly say "convert to markdown".

pdf-to-text

Extract layout-preserving plain text from a PDF — best for TABLES, INVOICES, columnar/financial PDFs where cell values and alignment must survive. Parse each PDF ONCE to a file. To find a specific fact, prefer a bounded `grep -n -i -C2 "term" file | head`. Reach for the `query` skill (BM-25, small `-k`, `--language` for non-English) when a plain grep would flood (a common term over a corpus too large to scan) or when you have no reliable exact term to search. Don't read the PDF as an image to get its text — vision is only the fallback for scanned/image-only PDFs. Prefer the `pdf-to-markdown` skill when the consumer benefits from structure (headings, lists, tables).

Nutrient Document Engine

Self-hosted, on-premises document processing server. Provides the same core operations as Nutrient DWS but runs in the user's own infrastructure. Also backs the Nutrient Web SDK's server-backed mode — handling persistent annotation storage and Nutrient Instant real-time collaboration.

Documentation

Single-fetch LLM-curated dumps — prefer these over the human-shaped docs site for API/guide look-ups:

Example Repositories

Key Concepts

Docker image: pspdfkit/document-engine on Docker Hub.

License activation: set ACTIVATION_KEY (or the alias LICENSE_KEY — either works). The pre-rebrand PSPDFKIT_LICENSE_KEY is not the current name; the engine fails on startup with "No ACTIVATION_KEY or LICENSE_KEY set" if missing.

Nutrient Instant: real-time collaboration backbone shared across the Nutrient client SDKs (Web, iOS, Android, React Native, Flutter). Enable in Document Engine config and point the client at the engine URL.

Document Engine vs Nutrient DWS: Document Engine runs on the user's infrastructure (no data leaves the environment); Nutrient DWS is Nutrient's hosted cloud service. Use Document Engine when data residency or offline operation is required.
