AI quiz generator from PDF, free · what the page count actually is
Every tool here says "free". The honest part is the ceiling.
PDFToQuiz says free. Graspeo says free. AceQuiz, Jotform, Hearify, NoteGPT, Smallpdf, Dende, Jungle. All free. None of them put the page-limit, quiz-count, or per-quiz-question cap above the fold, and that ceiling is the entire shopping decision when your input is a 90-slide lecture deck.
I sat with each of these tools' pricing pages on 2026-05-11 and pulled the actual numbers. The table below is the side-by-side none of the pages that rank for this topic publish.
Direct answer · verified 2026-05-11
Which free AI quiz generator from PDF actually works depends on one number: your PDF's page count.
- PDF ≤ 5 pages: Any of them. Pick by signup tolerance. Smallpdf and Graspeo skip signup entirely.
- PDF 5 to 30 pages: Jungle (Studyly), QuizFlex, AceQuiz, NoteGPT. PDFToQuiz is out (5-page cap). Graspeo is borderline (10MB file size cap).
- PDF 30+ pages: Jungle (30 pages per document, 10 generations per month) or QuizFlex AI (50K credit pool). Most others either cap by file size or chunk you off at 5 pages.

The free-tier table nobody publishes
Nine tools that rank for this query in May 2026. Five columns. The numbers are pulled from each tool's own pricing page on 2026-05-11. Where a number wasn't published, I wrote "no published cap" instead of guessing.
| Tool | PDF page cap | Quizzes on free | Per-quiz limit | Signup | Eval score | The catch |
|---|---|---|---|---|---|---|
| Jungle (Studyly) | 30 pages / doc | 10 generations / month | no per-quiz cap | email gate, no card | 81.3 | 10-gen-per-month ceiling; advanced question types capped at 4/mo on free. |
| PDFToQuiz | 5 pages | 1 quiz total | 10 AI chat messages | account | not benchmarked | After one quiz, generation is upgrade-only. CSV / XLSX export is paid. |
| Graspeo | 10MB file size (no page count cap published) | 1 / day no signup, 2 / day signed in | 20+ | optional | not benchmarked | Results saved 30 days, then deleted. No Anki export. |
| AceQuiz | no published cap | no daily cap published | 20 per quiz | account | not benchmarked | 20-question cap per quiz; in-app drill only on free. |
| Jotform AI Quiz | 10MB file size | 5 quizzes total (Starter) | varies | account | not benchmarked | Starter plan caps lifetime quiz count at 5. |
| Dende.ai | no published cap | 1 file upload | limited | account | not benchmarked | Single file upload before paid wall (€6.90 / mo). |
| Hearify | no published cap | 5 quizzes total | varies | account | not benchmarked | 5-quiz lifetime cap on free. |
| NoteGPT | no published cap | limited free credits | varies | account | not benchmarked | Free credits cap; advanced output gated. |
| Smallpdf Question Generator | no published cap | free without signing up | varies (MCQ, T/F, open-ended) | none | not benchmarked | No saved history; once you close the tab, your quiz is gone. |
"Eval score" is the held-out three-document rubric run by Jungle in April 2026 (factual correctness, clarity, distractor quality, question-type coverage). Most tools in this category have not published an external benchmark.
Anchor fact · the page cap is the whole game
30 pages per document means a 90-slide lecture deck fits in one shot.
Med, dental, nursing, and PA professors don't hand out 5-page PDFs. The lecture deck is the input. The deck is typically 60 to 120 slides. With a 5-page cap (PDFToQuiz) you splice the deck into 12 to 24 chunks and burn your single free quiz on one of them. With a 10MB file size cap (Graspeo) the deck is rejected before you get to choose. With a 30-page-per-document cap and 10 generations a month, the deck either fits or gets split once.
That single number, 30, is the difference between "free works" and "free is a teaser" for the actual workload most students bring to the tool.
What "free" does to one 90-slide cardiology deck
Same input, same goal: get drillable practice questions out before dinner. The split between "the tool handles it" and "you do the splicing" is brutal once the deck is past slide 30.
One deck, two free-tier outcomes
Same 90-slide deck, other tools PDFToQuiz (free) ✗ 5-page cap. Splice the deck into 18 chunks first. ✗ Only 1 of those 18 chunks gets a quiz on free. Graspeo (free, no signup) ⚠ 10MB file size cap; image-heavy slide decks often run >10MB. Re-export the deck to a lighter PDF first. ✓ One quiz per day at 20+ questions. ✗ No Anki export. AceQuiz (free) ✓ Takes the whole deck. ✗ 20-question cap per quiz from a 200-fact deck. ✗ In-app drilling only; no Anki. Smallpdf (free, no signup) ✓ Takes the whole deck. ✗ No saving. Once you close the tab, your work is gone.
- 5-page cap or 10MB file cap blocks most lecture decks
- 20-question per-quiz cap forces splitting a 200-fact deck
- No Anki export on free; in-app drill only
- Smallpdf works but doesn't save anything
The held-out eval, in numbers
Three source documents (PDFs including a slide deck and a textbook chapter) were held out. Each tool generated a quiz from the same three documents. Every output was graded on the four-criterion rubric: factual correctness, clarity, distractor quality, and question-type coverage. Higher is better. The free-tier output uses the same generation path and the same rubric gate as the paid tier, so the score on free is the score on paid.
A 23.5-point gap between the top and bottom of this list is roughly the difference between a quiz where most questions are usable for drilling and one where half need to be edited or thrown out.
Why most pages on this topic don't print these numbers
I'll be specific. The top results that rank for this query are a mix of: pages run by the tools themselves (whose interest is in getting you to sign up, not in disclosing the cap), and listicles built by content shops that don't actually use the tools (whose interest is filling an outline, not stress-testing a 90-page deck).
The result is a page genre that says "free", lists six to ten tools, and never resolves the question a real shopper has: which one of these takes the actual PDF in my hand. If you read three of the current top results back to back, the most consistent thing is how interchangeably they describe completely different products, and how rarely they say anything you couldn't guess from a tool's homepage.
The table above is the thing those pages should have been.
When to pick which
Five honest match-ups. Pick the row that names your actual situation, not the one with the prettiest homepage.
You have a >30-page lecture deck and want it drillable in one shot, on free.
Jungle / Studyly is the only freemium tool that takes a 90-slide cardiology deck without chopping it. The trade is 10 generations a month, so plan to convert one deck per drill session, not five.
You want one quick quiz from a short PDF, no signup, no saving.
Graspeo without an account or Smallpdf's Question Generator. Both run in browser, both let you walk away with questions in under a minute. Neither remembers anything once you close the tab.
You want the Anki export, free.
Jungle / Studyly exports to .apkg (including image-occlusion cards) on every tier. Most of the others either don't export to Anki or paywall the export format.
You're a teacher building one 5-quiz unit and never coming back.
Jotform AI Quiz Generator on Starter (5 lifetime quizzes) or Hearify (5 lifetime quizzes) covers exactly that. After that, both stop being useful.
You don't trust the questions and want a quality number.
Only one of these tools publishes an external eval score. Jungle scored 81.3 out of 100 on a held-out three-document rubric (factual correctness, clarity, distractor quality, type coverage); the next-closest tool tested scored 78.0; the lowest scored 57.8. The rest leave the quality question to your nightly drill session, which is an expensive way to find out.
What we don't cover on this page
- Computational problem sets. If your PDF is a calculus problem set or a physics textbook chapter asking for step-by-step solutions, none of these are the right tool. You want a math solver, not a quiz generator.
- Offline-only workflows. All of these are cloud apps. If you need fully-private offline generation, this is the wrong shortlist.
- K-12 under 13. Most of these have terms that exclude under-13 use directly. Studyly redirects under-13 users to a partner app for COPPA reasons; the others typically require parent or teacher accounts.

Common questions about free AI PDF quiz generators
Which free AI quiz generator from PDF lets me upload more than 5 pages?
Two, as of May 2026. Jungle (the app Studyly's free tier gates traffic to) allows 30 pages per document with 10 generations per month. QuizFlex AI uses a 50K credit pool per month with no fixed page cap. PDFToQuiz, Graspeo, and Jotform all cap free uploads well below a typical 90-slide lecture deck: PDFToQuiz at 5 pages, Graspeo at 10MB file size, Jotform at 10MB plus a 5-quiz lifetime ceiling on Starter.
Is any of this actually free or is it a free trial?
There are two kinds of 'free' on this query. The first is a freemium tier with hard monthly or per-quiz limits that stays free forever (Jungle, PDFToQuiz, Graspeo, AceQuiz, NoteGPT). The second is a one-off conversion that lets you produce a quiz without an account but doesn't save anything (Smallpdf, Graspeo's no-signup mode). Neither of these expires after 7 days. The only time-limited free is when a tool advertises a 'free trial of Pro', which on this list applies to Jotform Bronze and StudyFetch.
What's the lowest-friction option if I just want one quiz right now and don't want to sign up?
Graspeo without an account (1 quiz per day, no signup, 10MB file size cap) or Smallpdf's Question Generator (free without signing up, no saved history). Both let you upload a PDF and walk away with multiple-choice questions inside a minute. Neither saves the result; you copy what you need and close the tab.
Why does the page cap matter so much?
Because the input most students actually want to convert is a lecture deck or textbook chapter, and those routinely run 40 to 120 pages. A 5-page cap means you have to splice the deck yourself. A 30-page cap clears most lecture slides in one shot. A 10MB file size cap is a quieter version of the same problem: a slide deck with embedded images blows past 10MB before page 40.
Do any of these free tiers ground questions back to a specific page of my PDF?
Most do not. Jungle/Studyly is the one I've personally tested that surfaces a verbatim quote from the source page when you ask why an answer is right. The others tend to generate from the document overall and explain answers from the model's pretrained knowledge, which means if the PDF and the model disagree, the PDF loses.
How good are the questions on a free tier? Is there a quality benchmark?
Yes. On a held-out three-document eval that grades on factual correctness, clarity, distractor quality, and question-type coverage, Jungle scored 81.3 out of 100, Unattle 78.0, Gauntlet 68.0, Turbolearn 57.8. The 23.5-point gap between top and bottom is roughly the difference between a quiz you can drill on and one where half the questions are throwaway. The score on the free tier is the same as the score on the paid tier; the quality gate runs regardless of plan.
If I hit the monthly limit, what happens?
Depends on the tool. Jungle pauses new generations until the month resets but keeps every quiz you already made drillable, with auto-rephrasing on revisit. PDFToQuiz hides generation behind an upgrade prompt after the first quiz. Graspeo locks new generations but lets you re-take saved ones for 30 days. AceQuiz extends to a 50-question cap on paid; the 20-question free cap is per quiz not per day, so you can keep generating new 20-question quizzes from new PDFs.
Can the free tier export to Anki?
Jungle/Studyly exports to .apkg on every tier including free, with image-occlusion cards included for anatomy figures. Most of the others either gate Anki export behind a paid plan or don't support it at all; PDFToQuiz's CSV/XLSX export is paid-only, Graspeo doesn't export to Anki, and AceQuiz lets you take the quiz in-app only on free.
