Royalty-free vs copyright-free vs public domain: what each label actually lets you do

Search any stock music site and you will see three phrases used almost interchangeably: royalty-free, copyright-free and public domain. Creators treat them as synonyms for "safe to use". Then a Content ID claim lands on a video, or a client's lawyer asks for the licence, and it turns out the three words meant very different things.

This guide separates them. It is for producers using other people's tracks in videos, games, podcasts or client work, and for artists deciding how to offer their own music. If you want the detail on when old songs actually become free, read our guide to when music enters the public domain; this one is about the labels and what to check before you trust them.

Start from the default: everything is copyrighted

The most useful fact here is the starting point. Under the Berne Convention, copyright cannot depend on formalities (WIPO summary of Berne, Article 5(2)). Nobody has to register a track or print a © symbol for it to be protected. The US Copyright Office puts it plainly: protection exists from the moment a work is created and fixed in a tangible form (U.S. Copyright Office FAQ).

So the question is never "is this copyrighted?" For anything made recently, it almost certainly is. The question is "what permission do I have, from whom, and on what terms?" Remember too that a recording usually carries two copyrights: one in the composition and one in the sound recording. A label has to cover both.

Royalty-free: a payment model, not a legal status

"Royalty-free" describes how you pay. You pay once (or subscribe) and you do not pay a further fee each time the track is used, streamed or broadcast. The music is still fully copyrighted. You are a licensee, and the licence text decides what you can do.

That text is where the surprises live. Typical limits to look for:

• Media and channel. Some licences cover online video but not broadcast, cinema, games or paid ads.
• Reach or seats. Some cap views, units sold or the number of people at the company who can use the track.
• Term. Some licences end when a subscription lapses for new projects, while keeping already-published ones covered. Our look at what you keep after cancelling sample subscriptions shows how much this varies.
• Resale and standalone use. Almost every library bans re-releasing the track itself, alone or as the main feature of your product.

"Royalty-free" also does not mean "no royalties are ever paid by anyone". In many countries the composer of a library track is a member of a collecting society, and broadcasters and venues pay that society for a blanket licence to perform its repertoire (ASCAP licensing FAQ). You, the video maker, usually owe nothing extra, but a TV channel airing your film may still report the cue. That is normal, and it is not the library breaking its promise.

Copyright-free: usually a marketing phrase

Copyright law does not define "copyright-free". When a website uses the phrase, it means one of three things:

1. The owner has waived copyright as far as the law allows, normally with Creative Commons' CC0 tool (Creative Commons: CC0). This is the honest version.
2. The track is under an open licence with conditions, such as CC BY (credit required) or CC BY-NC (no commercial use). That is not copyright-free at all; it is copyrighted music with a generous licence. Our guide to Creative Commons licences for music explains each element.
3. It is royalty-free music relabelled because "copyright-free" gets more searches. The licence is still there, somewhere.

Even platform libraries come with strings. YouTube's own Audio Library requires attribution in the video description for tracks under a Creative Commons licence (YouTube Help). "Free to use" and "no conditions" are different promises.

Public domain: a legal status with no licence at all

Public domain means no copyright applies, usually because the term has run out or, in some countries, because the work was never eligible. Nobody can license it, because nobody owns it.

The catch for music is that the composition and each recording run on separate clocks, and countries set different terms. A centuries-old melody is free, but a 2019 orchestral recording of it is a new sound recording, and a modern arrangement may be a new work. Those layers are covered in our public domain guide. "Public domain classical music" on a stock site usually means a public-domain score, recorded and licensed by the site.

A five-step check before you use a track

1. Find the licence text, not the badge. A "royalty-free" or "copyright-free" tag on a thumbnail is not a licence. Save the actual terms page, and note the date.
2. Match the use. Write down where the track will appear: platform, paid or organic, territory, how long. Check each against the licence. If the licence is silent on a use, treat it as not covered.
3. Check both layers. Who owns the composition and who owns this recording? For "public domain" claims, confirm the recording itself is free, not just the tune.
4. Check for Content ID. Many library tracks are registered with YouTube's Content ID. Ask the library how to clear a claim, and keep your licence or download receipt with the project. Our Content ID guide covers disputes.
5. Keep proof. Store the licence PDF or page capture, the invoice and the track ID with the project files. A licence you cannot show is hard to rely on years later when a client asks.

What we think

The labels are not the real problem. The problem is that the music economy has trained creators to think of tracks as "safe" or "unsafe" when they are really bundles of permissions. That framing quietly hurts artists on both sides. The video maker who trusted "copyright-free" loses income to a claim. The composer whose track was scraped and reuploaded to a "free music" site loses the licence fee and gets blamed for the claim.

If you make music and want people to use it, be explicit. Pick a real licence, CC0 if you truly want no conditions, a Creative Commons licence if you want credit, or a written royalty-free licence if you want paying customers, and put the exact terms on the same page as the download. Say whether the track is in Content ID and how to get a claim released. That one paragraph saves your users from guesswork and protects your income better than any watermark.

If you are using other people's music, the habit that matters is boring: read the terms once, save them, and match them to the use. "Royalty-free" is a fine deal when you know what it covers. "Copyright-free" deserves a second look every time. And "public domain" is real, but only for the specific layer that has actually expired.

This guide is general information, not legal advice. For a high-stakes use such as broadcast, a national ad campaign or a film release, have the licence reviewed by a lawyer in your territory.
