The short answer.In the United States, downloading a YouTube video for personal use sits in a legal grey zone. It violates YouTube's Terms of Service in every case (a contract issue, not a copyright issue). Whether it also infringes copyright depends on the source video's licence and whether your specific use qualifies as fair use under 17 U.S.C. §107. Downloading copyrighted music for offline listening generally does not qualify as fair use. Downloading Creative Commons or public-domain videos is fine.

The legal framework — three layers, not one

The reason "is it legal?" is hard to answer in a sentence is that there isn't one legal regime governing the question — there are three, and they sit on top of each other. To assess any specific download you have to look at all three:

1. Federal copyright law. 17 U.S.C. §§101 et seq. defines what counts as infringement and what defences (like fair use under §107) might excuse it. This is the regime where rights-holders can bring civil suits or, in extreme cases, refer matters for criminal prosecution.
2. The Digital Millennium Copyright Act (DMCA). 17 U.S.C. §1201 specifically prohibits circumventing "technical measures" that protect copyrighted works. Whether YouTube's streaming protocol is such a measure is contested — see the §1201 section below.
3. Contract law — YouTube's Terms of Service. The terms you agreed to when you used YouTube are a binding contract under state contract law. ToS violations aren't crimes and aren't copyright infringement; they're breaches of contract, with breach-of-contract remedies (typically: account termination).

Most personal-use YouTube downloads clearly violate layer 3 (the contract). Whether they violate layers 1 and 2 depends on the source video, the use, and the technical method. The rest of this page works through each layer in turn.

Two separate issues — copyright vs Terms of Service

People conflate these and they shouldn't be conflated.

• Copyright is a federal statutory regime. Infringement is a violation of US law and can be enforced by the rights-holder in federal court. Penalties can be significant.
• Terms of Service is a contract between you and YouTube/Google. Violating it can get your YouTube account suspended or permanently banned, but it's not a crime and you don't go to jail for breach of contract.

Most YouTube → MP3 conversions clearly violate ToS. Whether they also violate copyright is a separate question that depends on the source.

When it's clearly legal

Creative Commons-licensed videos

When a YouTube creator chooses the "Creative Commons — Attribution" licence (CC BY 3.0) at upload, anyone can download, modify, share and even use commercially — provided they attribute the original creator per the licence terms. You can find CC-licensed videos by filtering YouTube search under "Features → Creative Commons."

Public domain

Works whose copyright has expired, or that were never copyrightable in the first place (US government works, for example), can be downloaded and used without restriction.

Your own uploads

You retain copyright to videos you upload to YouTube (the YouTube licence is non-exclusive). You can download your own content at any time.

YouTube Premium offline mode

YouTube's own paid offline feature is the unambiguously sanctioned way to play YouTube content offline. The file stays inside the YouTube app and can't be exported, but for use cases like "listen on a flight" it's the cleanest answer.

When it's clearly illegal

• Commercial use of downloaded copyrighted material — using it in a paid product, an ad, on a monetised stream, or selling the file.
• Redistribution — uploading the downloaded file elsewhere, sharing it publicly, or seeding it via torrents.
• Removing or modifying copyright management information (artist names, watermarks) before redistribution — separately prohibited by 17 U.S.C. §1202.

The grey area — personal use of copyrighted content

The honest analysis: you're almost certainly violating YouTube's ToS, and you're probably committing copyright infringement, but in practice individual personal-use downloads are almost never enforced against by rights-holders. The much more common consequence is your YouTube account being suspended.

That doesn't make it legal. It just means the practical risk is low for most individual users. We don't recommend relying on "they probably won't catch me" as a legal strategy.

What "copyright infringement" actually means under US law

A copyright owner has the exclusive right (under 17 U.S.C. §106) to do — or authorise others to do — six specific things with their work: reproduce it, prepare derivative works from it, distribute copies, perform it publicly, display it publicly, and (for sound recordings) perform it publicly via digital audio transmission. Doing any of those without authorisation, and without a defence, is infringement.

Downloading a YouTube video is most naturally characterised as reproduction— making a copy of a copyrighted work. The fact that YouTube is also delivering you a copy when you stream the video doesn't help you, because that streamed copy is authorised by the rights-holder (via YouTube's licence) as a transient buffer for live playback, not as a permanent copy. Saving the file shifts the act from authorised streaming to unauthorised reproduction.

The penalties on paper are dramatic: statutory damages of $750 to $30,000 per work for ordinary infringement, up to $150,000 per work for wilful infringement (17 U.S.C. §504). In practice, those numbers are almost never applied to individual personal-use cases — they're what the rights-holder can theoretically ask for in a civil suit, not what end-users actually pay. The bigger practical risk for individuals isn't a $30,000 judgment; it's a settlement-letter scheme (the so-called "copyright trolls" pattern that targeted BitTorrent users a decade ago) or a takedown of cloud-storage accounts that hold infringing files.

What is fair use, really?

17 U.S.C. §107 lets a court excuse what would otherwise be infringement if the use is "fair" — judged on four factors:

1. Purpose and character. Non-commercial, educational, transformative uses lean toward fair use. Personal entertainment usually doesn't.
2. Nature of the work. Factual works lean toward fair use; creative works (most music, film, art) lean against.
3. Amount used. Smaller portions lean toward fair use. Downloading the entire song or video is the maximum amount.
4. Market effect. If the use substitutes for a paid version (i.e. you'd otherwise have bought it on iTunes / streamed it on Spotify), the use harms the market and leans against fair use.

For typical "I want this song offline" downloads, factors 2, 3 and 4 all weigh against fair use. The fact that the use is personal and non-commercial doesn't flip the analysis on its own.

How fair use applies to specific YouTube → MP3 scenarios

To make the §107 analysis less abstract, here's how it shakes out in five common situations:

• Downloading a copyrighted song to listen offline. Factor 1: personal/non-commercial (mildly favours). Factor 2: creative work (against). Factor 3: 100% of the work (against). Factor 4: substitutes for buying or streaming (strongly against). Net: probably not fair use.
• Downloading a clip to use in a critical review or commentary video. Factor 1: transformative, possibly commercial (mixed). Factor 2: creative (against). Factor 3: short clip, only as much as needed (favours). Factor 4: doesn't substitute for the original (favours). Net: often fair use — this is the classic protected use case.
• Downloading an educator's lecture for offline study. Factor 1: educational/non-commercial (favours). Factor 2: factual or mixed (mostly favours). Factor 3: full work (against). Factor 4: minimal market harm if the lecture is freely available (favours). Net: probably fair use, especially for currently-enrolled students of the educator.
• Downloading a Creative Commons-licensed video. Fair use doesn't even enter the analysis — the licence itself authorises the copy. Just follow the licence terms (usually attribution).
• Downloading content for archival because the uploader said the video is going to be deleted. Factor 1: archival/preservation (favours). Factor 2: creative (against). Factor 3: full work (against). Factor 4: depends on whether the work will remain commercially available elsewhere (mixed). Net: genuinely uncertain. Libraries get specific exemptions under §108 that don't apply to individuals.

The pattern: fair use is most likely when the use is transformative, the amount used is small, and the use doesn't replace a market the rights-holder is in. It's least likely for full-work copies that substitute for buying or streaming.

DMCA §1201 — circumvention of technical protections

17 U.S.C. §1201 prohibits circumventing "technical measures" that effectively control access to copyrighted works. Whether YouTube's streaming protocol counts as such a measure is contested. The most public test was the 2020 RIAA / youtube-dl dispute, in which GitHub initially removed the youtube-dl repository under a §1201 notice and later restored it after pushback from the EFF and Stanford CIS. The underlying legal question wasn't resolved.

The §1201 question that hasn't been resolved

The 2020 RIAA / youtube-dl dispute crystallised the open legal question: does YouTube's streaming protocol, with its "rolling cipher" and signature-based URL signing, count as a §1201 "technical measure that effectively controls access to a work"?

The RIAA argued yes — the rolling cipher is a deliberate barrier that downloaders must specifically work around. The EFF and Stanford Center for Internet and Society argued no — the signature scheme isn't designed to control access (everyone with a browser already has access); it's designed for server-side rate-limiting and DRM-adjacent purposes that don't fit §1201's definition. The dispute ended with GitHub restoring youtube-dl after the EFF's legal-counsel letter, but the underlying §1201 question wasn't litigated — it was effectively dropped.

That leaves a genuinely uncertain area of law. A future court case could go either way. For individual users running yt-dlp or browser-based converters, the practical risk of a §1201 claim has been near zero historically, but the law itself isn't settled.

State-by-state and country-by-country variation

The analysis above is US federal copyright law, which preempts most state-level copyright issues. Across borders, the rules diverge meaningfully:

• European Union. The 2001 Copyright Directive permits a "private copying" exception in member-state law. Most EU countries — Germany, France, Spain, Italy, the Netherlands — explicitly allow personal copies of legally accessed media, often funded by a private-copying levy on blank media and storage devices.
• United Kingdom. A 2014 personal-copies exception was struck down in 2015 (BASCA v. Secretary of State for Business). UK law currently provides no private-copying exception, making it stricter than most of the EU on personal use.
• Canada. The Copyright Modernization Act (2012) added a "Reproduction for Private Purposes" provision (§29.22) that arguably permits some forms of personal-use copying, though the conditions are specific.
• Australia. A "format-shifting" exception exists for some media (CDs to MP3, for example) but doesn't clearly cover online video downloads.
• Germany specifically. Has had several court decisions specifically about YouTube downloaders. The most cited is the 2017 Stream Ripper / Convert2MP3 case, which treated the operator of a converter as the infringing party rather than end users.

The international pattern: end-user personal-use copying tends to be either explicitly permitted (most EU countries) or ignored in practice (US, Canada, Australia). Operators of large-scale conversion services face more enforcement risk than individual users in most jurisdictions.

The licence terms most YouTube uploads carry

When a creator uploads a video to YouTube, they retain copyright. They grant YouTube a non-exclusive licence to host, stream and display the video, and they grant YouTube users (i.e. you) a sub-licence to view it via YouTube's tools. That sub-licence is for viewing, not copying. Specifically, section 6 of YouTube's ToS reserves: "You may access Content for your information and personal use solely as intended through the provided functionality of the Service."

"The provided functionality of the Service" means the YouTube player, the YouTube Premium offline mode, and YouTube's official APIs as authorised by Google. Third-party download tools aren't "the provided functionality" — that's the textual basis for ToS violation. Whether a court would treat a click-through ToS as enforceable for casual users (browse-wrap problems aside) is a separate question, but as a contract-law matter the violation is clear.

This contract framework explains why YouTube enforcement looks the way it does: account suspensions and channel terminations, not lawsuits. Breach of contract typically gets you removed from the service, not sued.

What about Creative Commons in detail

YouTube uploaders can mark their content as Creative Commons — Attribution (CC BY 3.0)at upload time. This is the only Creative Commons licence YouTube directly supports in its UI; if a creator wants to use a different CC variant (CC BY-SA, CC BY-NC, etc.) they have to specify it in the description rather than via YouTube's licensing dropdown.

Under CC BY 3.0 you can:

• Download the video by any means.
• Modify, remix and re-edit it.
• Redistribute it on any platform.
• Use it commercially — in a paid product, a monetised stream, an ad campaign.

What you have to do in return is straightforward: attribute the original creator (their YouTube channel name, a link back to the source video) and not imply the creator endorses your use. For our deeper guide on CC and how to find legitimately re-usable content, see copyright-free YouTube channels.

Could I actually be sued?

For a personal-use download? Almost no individual has been targeted purely for personal use of a converter. Lawsuits in this area have been against the converter operators (e.g. Stream Ripper / FLVTO cases in Germany and the US) rather than end users.

That said, "rare" isn't "never," and YouTube account suspension for ToS violations is common.

Safer alternatives

• YouTube Premium offline — the official, fully legitimate offline option (in-app only).
• Spotify / Apple Music — for licensed music, the streaming service is almost always cheaper than dealing with the legal grey zone.
• Creative Commons content — filter YouTube search by Features → Creative Commons.
• Direct purchase — Bandcamp, iTunes Store, the artist's own site. Often DRM-free.
