Turn a PDF into Quizlet-style flashcards in minutes
Upload a PDF, slides, notes or a photo of a page and DeckOwl builds flashcards from your own material, ready for spaced repetition.
Why build flashcards from your own PDF
Most students who want a way to turn a class PDF into study cards need something they can review in short sessions, not a ready-made deck. With DeckOwl you can make Quizlet-style flashcards from a PDF using your own file, so the cards match what your instructor actually covered.
- Works with PDF, DOCX, PPTX, plain text and photos of pages
- Spaced repetition schedules reviews so cards you miss come back sooner
- Study in the browser on the free plan with 3 generations per month
- Export to Anki, PDF, DOCX or CSV on the Plus plan
From your own PDF
Upload a PDF and get flashcards built from your lecture material, not a generic set.
Spaced repetition

Export when you need it

Frequently asked questions
How many flashcards should I make for the Pythagorean theorem?
A focused set of about 20 cards works well, covering the formula, identifying the hypotenuse, and a few worked examples. Add more cards for any step you keep missing.
How do I study the Pythagorean theorem with flashcards?
Put a² + b² = c² on one side and the meaning of each variable on the other, then practice spotting the hypotenuse before you solve. Shuffle the cards so you recall each step rather than memorizing their order.
Can I export my PDF flashcards to Anki?
Yes, export to Anki, PDF, DOCX and CSV is a paid feature on Plus, which costs $39 per year or $7.99 per month. The free plan lets you study in the browser without exports.
Is there a free way to make flashcards from a PDF?
