How do I import PDFs to NotebookLM?
Open a notebook, click Add Sources, choose Upload, and drag your PDFs in. Up to 200 MB per file, 500K words per source. For batch import of many PDFs (e.g., a Zotero library), upload in groups within the limits.
In more detail
PDF upload is native to NotebookLM. From any notebook, click "Add Sources" in the left panel, choose "Upload," and drag-drop PDF files. Per-file limit: 200 MB or 500K words. For batch operations (e.g., 50 papers from a literature review), upload in groups; NotebookLM processes each. For OCR'd scans, run OCR first (Adobe Acrobat, ABBYY, free online OCR). For protected/encrypted PDFs, remove the protection first. For Zotero users: export PDFs from a Zotero collection, then drag into NotebookLM. Notebook Toolkit captures PDFs directly from arXiv and PubMed pages with metadata.
