How to get flashcards out of a PDF

A lecture PDF often holds more terms than you can memorize in one sitting, so flashcards from a PDF let you turn that file into questions you can practice on your phone or laptop. You keep your own material as the source, so the cards match what your instructor actually covered.

Upload PDFs, DOCX, PPTX, plain text, or photos of pages read with text recognition
Review every card against the source before you start studying
Use spaced repetition so cards return just before you would forget them
Export to Anki or CSV on Plus when you want to study outside the browser

Example intro biology flashcards on cell structure

What organelle produces most of a cell's ATP?The mitochondrion, because it carries out most of cellular respiration.

What is the function of the cell membrane?It controls what enters and leaves the cell because it is selectively permeable.

How do prokaryotic and eukaryotic cells differ?Eukaryotic cells have a membrane-bound nucleus and membrane-bound organelles, while prokaryotic cells do not.

What does the Golgi apparatus do?It modifies, sorts, and packages proteins and lipids for transport within or out of the cell.

What is osmosis?The movement of water across a selectively permeable membrane from lower solute concentration to higher solute concentration.

Generate the full set

Works with your own PDFs

Upload a PDF, along with DOCX, PPTX, notes, or photos of pages, and DeckOwl reads the text and builds cards from it.

Spaced repetition built in

Cards come back at the intervals where you are most likely to forget them, so you spend time on the terms you still miss.

Quizzes and mind maps too

If flashcards are not enough, the same upload can produce multiple choice, true/false, and short answer quizzes with explanations, or a mind map.

How it works

Upload your PDF

Drop in the file from your course or download. No credit card is needed to start.

Review the generated cards

Check the questions and answers against the source, then edit any card that needs more or less detail.

Study on a schedule

Work through the deck in the browser. Spaced repetition brings back the cards you are about to forget.

Start by uploading the PDF and reading through the generated cards. Remove anything trivial, merge cards that repeat the same idea, and add your own if something important is missing. A focused deck of 30 to 60 cards from one chapter is usually easier to review than a deck that tries to cover a whole course.

The free plan includes 3 generations per month and studying in the browser. Exporting to PDF, DOCX, Anki, or CSV is part of the Plus plan at $39/year or $7.99/month, and Plus also gives you unlimited generations.

Frequently asked questions

How many flashcards should I make from one PDF chapter?

Most chapters work well with 30 to 60 cards, one idea per card. Cover the key terms, definitions, and processes, and skip sentences that only add background.

What makes a good flashcard from a PDF?

Write the front as a specific question or term and the back as a short answer you can say from memory. Avoid cards that ask for a whole paragraph, since those are hard to check during review.

Can I export flashcards made from a PDF to Anki?

Yes, Anki export is included in the Plus plan at $39/year or $7.99/month. The free plan lets you study the cards in the browser but does not include exports.

Is it free to turn a PDF into flashcards?

You can start free with no credit card and make 3 generations per month. Plus removes the monthly limit and adds PDF, DOCX, Anki, and CSV export.
