When a document is too large for the context window, convert only the part you need. GroupDocs.Markdown.Mcp lets an AI agent turn selected pages or worksheets into Markdown locally, from Claude Desktop, Claude Code, Cursor or GitHub Copilot, so the LLM reads one chapter and not the whole book:

Konwertuj strony 40 do 52 z handbook.pdf do formatu Markdown.

The step‑by‑step version with config and troubleshooting is in the documentation: How to convert just one section of a document to Markdown.

Co oszczędza konwersja zakresowa?

Every word you put in a prompt is read, billed by the model provider and competes for attention with every other word. Most questions about a long document concern a small part of it. Converting everything first, then asking the model to ignore most of it, pays for the whole document on every question.

The saving is easy to measure on a document you own. Here is one real measurement, with its method stated. The file is the Markdown source of this server’s own licensing page in the documentation. We split it after the front matter and counted whitespace‑separated words, code blocks and Hugo shortcode markup included (the whole page is 810 words without the shortcodes). The table illustrates the ratio between a section and its page; it is not a measured result of the pages option, which selects pages, not headings:

Sekcja strony Słowa
Wprowadzenie i trzy tryby licencjonowania 167
Ograniczenia trybu ewaluacji 93
Stosowanie licencji 78
Licencjonowanie rozliczane (pay‑per‑use) 366
Potwierdzanie, który tryb jest aktywny 113
Uzyskiwanie licencji 27
Cała strona 844

A question about which licensing mode is active needs only the 113‑word section. That is about 13 percent of the page, or roughly 7.5 times shorter than the whole. The count is in words because tokens depend on the model’s tokenizer; the token count moves with the word count, and we have not put a token figure here that we did not measure. The page is short on purpose. Your handbook will be larger, and the ratio is yours to count.

Sposób 1: Które strony mogę podać bezpośrednio?

If you know the pages, say so. pages on convert_to_markdown takes a comma‑separated list of 1‑based numbers, such as "40,41,42". There is no range syntax in the parameter; the agent expands “40 to 52” into the list for you. Leave pages out and the whole document converts.

Konwertuj strony 40 do 52 z handbook.pdf do formatu Markdown.

The result is a saved .md file and the content returned inline. Long output is truncated inline, and the saved file holds the full text.

Sposób 2: Jak przekonwertować tylko rozdział 3?

The tool has no heading‑scoped option, so “chapter 3” has to become page numbers first. Do it in two small steps:

Ile stron ma handbook.pdf i jaki jest jego tytuł?

get_document_info answers from the file without converting it: pageCount, title, author, fileFormat and isEncrypted. It also tells you early if a password is needed. Next, convert the table‑of‑contents pages, read them, and ask for the range they name.

Example session (abridged):

You:   How many pages does handbook.pdf have, and what is its title?
Agent: get_document_info -> pageCount: 212, title: "Operations Handbook".
You:   Convert pages 3 to 4 (the table of contents), then convert chapter 3.
Agent: convert_to_markdown (pages: "3,4") -> contents read: chapter 3 runs pages 61 to 64.
       convert_to_markdown (pages: "61,62,63,64") -> saved chapter 3 as Markdown.

Two small conversions replace one enormous one.

Sposób 3: Jak pobrać jeden arkusz z skoroszytu?

In XLSX, XLS and ODS files the numbers select worksheets, not printed pages:

Konwertuj arkusz 2 z modelu do formatu Markdown.

That puts one table into the document without the other sheets that sit in the same workbook.

Kiedy konwersja zakresowa jest warta dodatkowego kroku?

  • Kontekst. LLM otrzymuje tylko tę część, która odpowiada na pytanie, a długie dokumenty pozostają w oknie kontekstowym.
  • Koszt rozliczany. Przy licencjonowaniu rozliczanym płacisz za to, co przetwarzasz, więc mniejsza liczba stron to niższy rachunek.
  • Jakość wyszukiwania. Indeks zawierający jedynie istotny załącznik nie jest rozcieńczany przez resztę katalogu przy każdym zapytaniu.

If the whole document is the job, do not scope. Convert it once and keep the Markdown.

Szczere ograniczenia: strony w trybie ewaluacji

Without a license the server runs in evaluation mode: only the first 3 pages are processed, with an evaluation watermark on each. This overrides pages. Asking for pages 40 to 52 in evaluation mode returns pages 1 to 3 without an error, so a chapter from the middle of a book is not possible to test unlicensed. If the output does not start where you expected, call get_license_status first.

A table of contents can use printed page labels. If the converted pages do not start at the expected heading, ask the agent to convert neighbouring pages and adjust the list; get_document_info gives the total page count, which bounds the list.

Najczęściej zadawane pytania

Jak przekonwertować tylko rozdział 3 do Markdown?

Find the page numbers of the chapter first, then pass them in pages. Ask the agent to convert the table‑of‑contents pages, read them, and request the range they give.

Co zrobić, gdy dokument jest za duży dla okna kontekstu?

Convert part of the document, not all of it. Use pages to select the pages or worksheets that answer your question, and check the page count with get_document_info before you start.

Czy mogę przekonwertować strony PDF od 10 do 20 do Markdown przy użyciu AI?

Yes. Ask in plain language, “Convert pages 10 to 20 of report.pdf to Markdown”, and the agent sends the expanded list of page numbers. Unlicensed, only the first 3 pages are processed.
