PDF to Anki,
from the dropped file to a deck you have read.

Which PDFs make it into Anki cleanly

PDF to Anki sounds like one move, but it is really two: pulling clean text out of the file, then importing that text as cards. The first step decides everything, and it happens before a single card is written: whether the PDF carries real text or just a picture of it. A PDF exported from Word, Google Docs, Keynote or a digital textbook keeps a text layer you can select with the cursor, and that layer is what turns into cards. A photocopy run through a scanner, a phone photo saved as a PDF, or an old library scan is a stack of images, and there are no words in an image to pull into a deck.

Assuming the text is there, PDF structure still shapes what you get. Flowing prose, one column, converts almost line for line. A two-column layout can interleave the columns as it reads, so give the cards a pass before importing. Tables and equations arrive as a run of loose cells or symbols rather than a tidy row, and a figure or diagram simply is not text, so the caption comes through and the picture does not. Knowing that up front is the difference between a deck you trust and one you quietly stop reviewing.

Three lines of a PDF, three cards

Cards are only as good as the sentence behind them, which is why every one keeps its source line. Here is the shape of what comes back from a few ordinary textbook lines, source on top, card underneath.

Read one card against its source and the tool explains itself. A card that misread a footnote or a broken PDF line shows the garbled source right next to it, so it never reaches your collection by accident.

The import, from a PDF-made file

The file you export is plain tab-separated text, one card per line, front and back split by a tab. That is exactly what Anki's own importer expects, so nothing proprietary sits between the PDF and your deck.

1. Drop the PDF in with the tool set to flashcards.
2. Read the cards. Watch for the hyphen a PDF sometimes leaves in a word split across a line, and for a two-column page that read out of order. Both are obvious with the source line showing.
3. Click the Anki export to download the tab-separated file.
4. In Anki: File, Import, choose the file, note type Basic, separator Tab, field one to Front, field two to Back.
5. Import. Anki's own duplicate check flags any card already in your collection before it commits.

Where a PDF hits the edges

No OCR, so a scanned or photographed PDF returns a plain "no text found" instead of a made-up guess. No image occlusion, so the diagrams and labelled figures a PDF often carries do not become cards; only their captions do. The export is tab-separated text or a CSV, not a packaged .apkg, and reading a whole long PDF past the first 25,000 characters is on the Pro waitlist rather than available today. What is left, pulling the words out accurately and showing you where each card came from, is the part worth getting right.

The nearest tools that do this specific job, turning a PDF into Anki cards, mostly ask for an account before they show you a card. That is a reasonable business, and none of it makes them bad software. This page exists for the narrower case: a heavy Anki user who chose a desktop program with a manual over an app with a mascot, and would rather see the cards and walk away with the file. So the file is free, the PDF never leaves the browser, and the source line stays attached.

Next: feed the same notes through a practice test when you want to be questioned, or read the field-by-field Anki import in full.
