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.
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.
For extraction, we support all major languages including English, Spanish, Chinese, Japanese, and Korean.
No. Whether you have 10 highlights or 1,000, our **PDF annotation extractor** processes them all in a single pass. The only real limit is your computer's RAM, which is usually plenty for even the largest documents.
Yes. If you export your Kindle books as PDFs with highlights, our tool can easily parse them. This is the fastest way to move your mobile reading into your desktop knowledge base.
It is a specialized tool that scans the internal object structure of a PDF to find interactive elements like highlights, comments, and underlines. Unlike simple OCR, it captures the semantic metadata (like colors and author names) associated with those marks.
Simply export as Markdown (for Obsidian) or CSV/Notion Block. For Obsidian, you can drag the `.md` file into your vault. For Notion, you can paste the blocks directly or use the "Merge with CSV" feature in a database.
We support all modern browsers that implement **WebAssembly**, including Chrome, Firefox, Edge, and Safari. For the best performance with large files, we recommend using the latest version of Chrome.
