# docling vs pdf

Pick docling when the document is input: it parses PDFs (born-digital or scanned), DOCX, PPTX, XLSX, HTML, images and audio into one structured representation, and chunks a corpus for retrieval. Pick the Anthropic pdf skill when the document is output, or when you need to act on a PDF in place — fill a form, watermark, encrypt, split, merge. Reading and writing are different jobs and these two split cleanly along that line.

## Pick docling when

You need to get content OUT of documents: extraction, format conversion, table recovery, OCR on scanned pages, or chunking a document set for RAG.

## Pick pdf when

You need to produce or modify a PDF: generate one, fill a form, watermark, encrypt, split, merge, or extract from an encrypted file.

## Side by side

| | docling | pdf |
| --- | --- | --- |
| Direction | Read and convert — documents in, structured Markdown or JSON out | Read and write — produces and manipulates real PDFs |
| Formats | PDF, DOCX, PPTX, XLSX, HTML, Markdown, AsciiDoc, CSV, images, audio, XML | PDF only |
| Scanned pages / OCR | Yes — handles scanned PDFs | Extraction works on text layers; OCR is not its job |
| RAG chunking | Built in | No |
| Form filling / encryption | No | Yes |
| Runs locally | Yes — Python package, no API key | Yes — bundled scripts |
| Provenance | Verified (Docling project, LF AI & Data) | Official (Anthropic) |

## Bottom line

Use both, in sequence, for the common real workflow: docling to read a messy input corpus into structured text, then the pdf skill to emit the deliverable. The mistake is reaching for pdf when the input is a scanned contract, or for docling when the deliverable is a filled form — each will do a poor job of the other half. If you can only install one, install the one matching whether documents are arriving or leaving.

## Common questions

**Is docling better than the Anthropic pdf skill?**

Neither is better; they point in opposite directions. docling is the strongest reader and converter available, covering ten-plus formats including scanned PDFs and RAG chunking. The Anthropic pdf skill is the one that writes: generating PDFs, filling forms, watermarking, encrypting. Pick by whether the document is your input or your output.

**Can docling replace all four Anthropic document skills?**

For reading, largely yes — it parses DOCX, PPTX and XLSX as well as PDF. For producing polished Office files it cannot: docx, xlsx and pptx generate real formatted documents with formulas, layouts and speaker notes, which docling does not do.

**Does docling need an API key?**

No. It runs locally as a Python package (3.10+), and the skill ships inside that package so it updates with it. There is an optional remote service client if you prefer to run conversion on a server.
