The Ultimate Tool for Knowledge Workers

PDFs are where valuable information goes to hibernate. Whether it's an academic paper, a legal contract, or a technical manual, the insights you highlight often stay trapped inside the file. PDFAnnotations brings your notes back to life by extracting them into usable formats.

Why Local-First Matters

Unlike other online converters that require you to upload your sensitive documents to a cloud server, our tool uses WebAssembly to process files directly in your browser's memory. This means:

  • Zero Privacy Risk: Your confidential research, NDA-protected contracts, and personal journals never leave your device.
  • Blazing Speed: No time wasted uploading large files or waiting for server queues. Even 100MB+ PDFs are processed instantly.
  • No File Limits: Since we use your computer's power, you can process textbooks, long reports, and thesis papers without hitting paywalls.

Seamless Integration with Your Workflow

We built this tool specifically for the Personal Knowledge Management (PKM) community. If you use Obsidian, Notion, Logseq, or Roam Research, our exports are tailored for you. We don't just dump text; we format it with blockquotes, callouts, and back-links to create a seamless bridge between your reading and your thinking.

Frequently Asked Questions

Everything you need to know about our privacy-first tool.

Yes, 100%. We process all files locally in your browser using WebAssembly. Your documents never leave your device and are never uploaded to any server. You can verify this by turning off your internet—the tool will still work.
Yes. The tool is completely free to use. We believe knowledge tools should be accessible to everyone.
Currently, we support text-based PDFs (documents with a selectable text layer). For scanned images without OCR, you will need to run OCR software first.
No arbitrary limits. Since processing happens locally on your device, the only limit is your browser's available memory. Files under 100MB run instantly.
