Recognize Scanned PDF content and export Markdown with AlphaPDF Premium. Select languages and review the recognized result.

What to expect

Export recognized headings, paragraphs and tables for a Markdown documentation workflow. Use the original scan when available; adding resolution later cannot recover missing characters.

Review heading levels and reading order; Markdown does not reproduce precise page design. Proofread names and numbers; handwriting is best-effort.

What it does

This tool reads the text in a scanned PDF and gives it back as a Markdown file. Headings, paragraphs and simple tables are written as Markdown, which drops straight into a wiki, README or notes app. Scanned PDFs usually come from an office scanner or a scanning app, with one page per image. The cleaner the scan, the better the result, so use the original file rather than a copy that was printed and scanned again.

When to use it

Pick this when scanned manuals, printed procedures or old training guides need to become pages in a wiki or a documentation site. You get headings and paragraphs in a format that tools like GitHub, Notion and Obsidian understand, so moving a paper guide online becomes an edit rather than a rewrite.

Before you start

Review heading levels and reading order; Markdown does not reproduce precise page design. Proofread names and numbers; handwriting is best-effort.

Paste the result into a Markdown preview before publishing. Stray line breaks in the middle of sentences are the most common thing to tidy up. Recognition is never perfect. Names, amounts and dates deserve a careful check, and handwriting is read on a best-effort basis. Select every language on the page so the right characters are expected.

Up to 50 MB per input; 25 files and 500 MB per batch. PDF limit: 2000 pages. Up to 2 active jobs per account. Output limit: 1000 MB. Renderer limits can reject especially large pages or images.

Common questions

Will numbered steps stay numbered?

Numbered lists that are clearly laid out on the page usually come through as Markdown lists. Check steps that run across a page break.

My PDF already has text. Do I need OCR?

If you can select words in the PDF, it has a text layer. Try the regular PDF conversion tools first.

Are heading levels kept?

Headings are guessed from text size and position, so check the # levels before you publish.

Which languages can it read?

Choose the languages from the list before you start. Recognition works best when every language on the page is selected.
