The short answer
You can reach roughly A2 without paying anything — greetings, numbers, food, directions, simple sentences. Duolingo alone will take you most of that way, free and with ads. What no free resource gives you is B1, the level where you follow a conversation at natural speed: that needs roughly the same number of hours again, structured, with someone correcting you. The Indonesian market is too small for a complete course to be funded by advertising, and pretending otherwise wastes your first year.
Ranked by how far they actually take you, not by how loudly they advertise. We have included our own free plan in the list, with the same honesty applied to it.
Free with ads, no card. The most complete genuinely free path, and the best at building a daily habit.
Where it stops: The Indonesian course stops around A2. No Stories, no podcast, formal register only.
Unlimited authentic listening, from slow-and-scripted to native speed. The single best free way to train your ear.
Where it stops: No progression and no correction. You will understand more and speak no better.
Free, and the only free way to actually speak with correction from a native.
Where it stops: Needs a solid A2 first, or the conversation runs dry in five minutes and neither of you comes back.
An instant answer for any word, including rare ones.
Where it stops: They answer instead of you. Useful as a tool, useless as a teacher.
Spaced repetition, free and genuinely effective. Community Indonesian decks exist.
Where it stops: Quality varies wildly and nothing sequences it for you. You are building your own syllabus.
10 lessons and 100 flashcards, no credit card.
Where it stops: It is a sample of the syllabus, not a free course. The full A1→C2 programme is 12,99 € a month.
Occasionally a genuine public-domain or government-published text.
Where it stops: Most of what ranks is a pirated copy of a paid method — see below.
This is one of the most repeated searches on the topic, so it deserves a straight answer. Some genuinely free PDFs exist and are worth having — material published by universities, by public bodies, or old enough to be out of copyright. But most of what ranks for "free Indonesian PDF" is a scanned copy of a paid method, uploaded without permission. Two practical reasons to care beyond the legal one: these scans are usually outdated editions, and they come without their audio, which for a language you have never heard is the half that matters. A PDF that teaches you to read selamat siang without ever letting you hear it is not a bargain.
The CEFR scale runs A1 to C2. Free resources get you comfortably through A1 and most of A2: introductions, numbers, food, directions, simple present-tense sentences. B1 is where they all stop at once, and it is not a coincidence. B1 needs three things advertising cannot fund for a language this size: a sequenced syllabus past beginner level, correction of what you produce, and listening at natural speed with support. Indonesian has perhaps a few hundred thousand serious learners worldwide — a fraction of Spanish. There is no free complete course because nobody can pay for one.
See where each app stopsWorth being concrete, since the honest answer to "is free enough" is "for a while, yes":
None of that is an argument for paying today. It is an argument for spending your first month free, deliberately, and knowing in advance what you will hit.
Up to about A2, yes, and comfortably. Duolingo is free with ads and covers most of that ground, YouTube and podcasts give you unlimited listening, and language exchange lets you practise speaking at no cost. Past A2 there is no free structured programme in Indonesian — the market is too small to fund one with advertising.
Duolingo, without much competition. It is genuinely free, the Indonesian course is real, and the gamification is unusually good at getting people to come back daily. Its limit is the ceiling: the course stops around A2, has no Stories or podcast, and teaches formal register only.
Some are — material from universities, public bodies, or old enough to be out of copyright. But most of what ranks for that search is a scanned copy of a paid method, uploaded without permission. Beyond the legal question, those scans are usually outdated editions and come without the audio, which for pronunciation is the half that matters.
Realistically A2, which is around 100 to 150 study hours — roughly seven to ten months at half an hour a day. That is enough to travel, order food, ask directions and hold very simple exchanges. It is not enough to follow two Indonesians talking, which is B1 and needs about the same again.
No. There is a free Discovery plan — 10 lessons and 100 flashcards, no credit card — but that is a sample of the syllabus, not a free course. The full A1 to C2 programme is 12,99 € a month, with a 3-day trial and a 30-day money-back guarantee. We would rather say that plainly than have you find out after signing up.
Not that we are aware of for Indonesian specifically. Free courses that issue certificates tend to exist for high-volume languages where the provider monetises elsewhere. For Indonesian, CEFR-aligned certification is part of paid programmes.
