How a PDF quiz maker fits into studying

Your lecture PDF already contains the questions your exam will ask, so a PDF quiz maker saves the hour you would spend writing them by hand.

  • Multiple-choice, true/false and short answer questions from one upload
  • Explanations for every answer so missed questions teach you something
  • Works with PDF, DOCX, PPTX, plain text and photos of pages
  • Free plan includes 3 generations per month, with no credit card needed
Example biology quiz questions on cell structure
Which organelle produces most of a cell's ATP?The mitochondrion. It carries out cellular respiration, which generates most of the ATP the cell uses.
True or false: Osmosis moves water from a region of lower solute concentration to a region of higher solute concentration.False. Water moves toward the side with higher solute concentration, so it flows from lower to higher solute concentration only in the sense of following the gradient, not the reverse.
Which structure regulates what passes between the nucleus and the cytoplasm?The nuclear pore complex. It controls the transport of molecules in and out of the nucleus.
What do ribosomes do in a cell?They synthesize proteins by translating mRNA. They can float freely in the cytoplasm or be attached to the rough endoplasmic reticulum.
Which structure gives plant cells rigid support and is absent in animal cells?The cell wall, made mainly of cellulose. It keeps the cell from bursting when water enters by osmosis.

From any PDF

Upload PDF, DOCX, PPTX, plain text or photos of pages, and the quiz is built from your own material.

Three question types

Multiple choice, true/false and short answer questions, each with an explanation for the answer.

Study now or export later

Take quizzes in the browser on the free plan. Plus adds PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML.

How it works

Upload your material

Add a PDF, slides, a DOCX file or notes. Photos of pages are read with text recognition.

Choose question types

Pick multiple choice, true/false or short answer, then generate the quiz.

Check and practice

Read the explanations, then take the quiz in your browser.

DeckOwl reads the text of your file, picks out the key facts, and writes questions with answers and short explanations. Because the questions come from your own material, the quiz matches what your instructor covered rather than a generic textbook.

Testing yourself is one of the most reliable ways to remember material, so a quiz beats rereading the same pages. Generate a fresh quiz after each chapter and retake the questions you missed.

Frequently asked questions

How many questions should a practice quiz include?

Aim for enough questions to cover each main idea at least once, which is often 10 to 20 for a single chapter. Shorter quizzes work well for daily review, and longer ones suit a full exam.

How should I use a practice quiz to study?

Answer every question before reading the explanation, and note which ones you missed. Retake the missed questions a day or two later to check what you remember.

Can I export the quiz to Moodle or use it in my course?

QTI 2.1 and Moodle XML export are part of the Pro plan at $14.99 per month. Plus, at $39 per year or $7.99 per month, includes PDF, DOCX, Anki and CSV export.

Is there a way to try it before paying?

Yes, the free plan includes 3 generations per month and studying in the browser, and no credit card is needed to start. Exports are not included on the free plan.
