Convert a PDF to flashcards in one upload
Upload a textbook chapter, lecture slides, or notes. DeckOwl reads the text and builds flashcards you can review with spaced repetition.
How a PDF to flashcards converter works
A PDF to flashcards converter reads the text in your file, picks out the terms and ideas that matter, and writes each one as a question with an answer on the back. That saves the first hour most students spend copying highlights into index cards.
- Works with PDF, DOCX, PPTX, plain text, and images of pages
- Spaced repetition schedules reviews based on how well you recall each card
- The free plan includes 3 generations per month and browser study
- Plus removes the generation limit and adds PDF, DOCX, Anki, and CSV export
Reads the file you already have
Upload PDF, DOCX, PPTX, plain text, or a photo of a page. Photos are read with text recognition.
Spaced repetition built in
Cards resurface at the intervals that help you remember them, so you spend time on what you are about to forget.
Export when you need it
Plus exports your cards as PDF, DOCX, Anki, or CSV. The free plan keeps studying in the browser.
How it works
Upload your PDF
Drop in a chapter, a slide deck, or a set of notes. You can also use a photo of a printed page.
Review the cards
Check the generated questions and answers, then edit or delete any card that does not match your course.
Study on a schedule
Work through the deck in the browser. Spaced repetition brings back the cards you miss more often.
The result is only as good as the source, so start with the chapter or lecture you are actually tested on. Check each card once after it is generated, since a card that is wrong is worse than no card. Then study the deck in short sessions over several days, which works better than one long cram.

Frequently asked questions
How many flashcards should I make from one chapter?
Most chapters work well with 20 to 40 cards, one fact or concept per card. Cut any card that tests a detail you would not need on an exam.
What makes a good flashcard for studying cell biology?
Write the front as a specific question, such as what a structure does, rather than a single word. Keep the back short enough to recall in a few seconds.
Can I export the flashcards to Anki?
Yes, export to Anki is included in the Plus plan, which also supports PDF, DOCX, and CSV export. The free plan lets you study the cards in the browser without exports.
Is there a free plan, and do I need a credit card?
The free plan gives you 3 generations per month and browser study with no credit card required. Students with a school email get 40 percent off Plus.
