About Annotation Exporter
Your Highlights, Out of the PDF
You marked up forty pages of a paper and now the notes are trapped inside it. Annotation Exporter reads the annotation layer directly — highlights, sticky notes, underlines, squiggles, strikeouts, free text, and ink strokes — and assembles them into a notebook you can actually use.
Each entry keeps its page number, the comment text, the author, the date, and the color. For highlights and other text markup, the tool also recovers the exact words that were marked, so your notes quote the source instead of pointing at it.
Built for Literature Reviews and Study Notes
The output is shaped for the tools researchers and students already use.
Markdown for Obsidian
One .md file with a heading per page, quotes as blockquotes, and comments inline — drops straight into an Obsidian vault or any notes app.
JSON for Pipelines
A structured .json export with type, page, rect, author, date, color, and quote per annotation — ready for scripts, spreadsheets, or a review-roundup dashboard.
Chapter-Aware Grouping
When the PDF has bookmarks, annotations group under their chapter headings instead of one long page list.
Quoted Text Recovery
Markup quadPoints are mapped back onto the text layer, so a highlight exports the sentence it covered — not just a yellow rectangle.
The One Caveat: Scanned Pages
A highlight drawn over a scanned page marks an image, not text — there is nothing to quote because the page has no text layer. The annotation still exports with its position and any attached note, but the quote field comes back empty.
If your PDF is a scan, run it through OCR PDF first to give the pages a text layer, then export. The same applies to markup on flattened or rasterized documents.
How It Compares
Most tools can create annotations or delete them. Fewer can read them back out into something useful.

Read-Only and Fully Local
Exporting never modifies the source PDF — it is a read, not an edit. The file is parsed in your browser and the notebook is generated on your device, so a confidential review copy or an unpublished manuscript stays exactly where it started.
Pair it with Annotate PDF to mark up a document and Annotation Exporter to pull the notes back out — the full loop, without a server in the middle.
