Creative Commons licenses let you share and use creative work under conditions the creator sets, instead of defaulting to "all rights reserved"
A Creative Commons license is a legal tool that lets someone who made something — a photo, song, article, video, software code — say upfront what others can and cannot do with it. Instead of copyright's default rule (you own it completely, nobody else can touch it without asking), Creative Commons offers a middle ground: the creator keeps ownership but grants specific permissions in advance.
The license is a real legal document, not just a badge on a website. When you see a Creative Commons logo on a photo or article, it means the creator has chosen one of six standard licenses and published it under those terms. You do not need to ask permission or negotiate — the license tells you exactly what you can do.
This matters because most creative work online is locked down by default. A photograph on a website, a song on a streaming service, a research paper behind a paywall — you cannot legally copy, remix, or republish any of it without permission, even if the creator would say yes. Creative Commons licenses remove that friction for creators who want their work shared.
Key Takeaways
- Creative Commons licenses are legal documents that let creators grant specific permissions upfront instead of keeping all rights reserved.
- The six main licenses range from "you can use it for anything" (CC0) to "you can only share it unchanged and must credit me" (CC BY-ND).
- A Creative Commons license does not override copyright law — it is copyright law being used to open access rather than restrict it.
- You must follow the conditions of the specific license, usually crediting the creator and not using the work commercially, depending on which license applies.
The six Creative Commons licenses and what each one permits
Creative Commons publishes six standard licenses. Each one stacks conditions on top of each other, so understanding the building blocks makes them easier to remember.
The two foundational conditions are Attribution (you must credit the creator) and NonCommercial (you cannot sell it or use it to make money). A third condition, NoDerivatives, means you cannot change it. A fourth, ShareAlike, means if you remix it, you must release your version under the same license.
| License Name | What You Can Do | What You Cannot Do |
|---|---|---|
| CC0 (Public Domain) | Use, copy, modify, sell, republish — anything | Nothing; the creator has waived all rights |
| CC BY (Attribution) | Use, modify, sell, republish — but must credit the creator | Use without attribution |
| CC BY-SA (Attribution-ShareAlike) | Use, modify, republish — must credit creator and release your version under CC BY-SA | Use without attribution or under a different license |
| CC BY-NC (Attribution-NonCommercial) | Use, modify, republish — but only for non-commercial purposes and must credit creator | Sell it or use it commercially; use without attribution |
| CC BY-NC-SA (Attribution-NonCommercial-ShareAlike) | Use, modify, republish — non-commercial only, must credit, must release under same license | Sell it; use without attribution or under different license |
| CC BY-ND (Attribution-NoDerivatives) | Copy, republish, sell — but cannot change it and must credit creator | Modify it; use without attribution |
Most creators choose CC BY or CC BY-NC. CC BY-SA is common in open-source software and Wikipedia because it ensures improvements stay open. CC0 is used by creators who want no restrictions at all, including no requirement to credit them.
How to find and use Creative Commons licensed work
Creative Commons work lives in two places: repositories built specifically for it, and scattered across the regular internet with a CC license badge.
Wikimedia Commons is the largest repository — millions of photos, illustrations, and videos, most under CC BY or CC BY-SA. Unsplash, Pexels, and Pixabay offer free photos under CC0 or CC BY. Open Stax publishes textbooks under CC BY. Flickr lets you filter search results by license. Internet Archive hosts books, audio, and video under various CC licenses. YouTube creators can mark their videos as CC BY, and you can download and remix them legally.
When you find something with a CC license, the license badge or link tells you which one applies. Read it carefully — the difference between CC BY (you can sell it if you credit the creator) and CC BY-NC (you cannot sell it at all) matters if you plan to use the work commercially.
Always download or save a copy of the license itself, not just the work. If you use a photo in a presentation or article, include the creator's name, the title of the work, and a link to the license. Different licenses have slightly different attribution requirements, so check the specific one you are using.
Creative Commons licenses do not override copyright — they use it
A common misunderstanding: Creative Commons licenses do not remove copyright protection. They use copyright law to do the opposite of what copyright normally does.
Copyright is automatic — the moment you write something, take a photo, or record a song, you own it and nobody else can copy it without permission. Creative Commons licenses do not change that ownership. Instead, they let you say "I own this, and I am giving you permission to do X, Y, and Z under these conditions." The copyright still exists; the license just opens it up.
This means a Creative Commons license is legally binding. If someone uses a CC BY photo without crediting the creator, they have violated the license terms and can be sued, just like copyright infringement. The license is not a suggestion — it is a contract between the creator and anyone who uses the work.
When you cannot use Creative Commons work even if it is licensed
A Creative Commons license covers only the copyright in the work itself. It does not cover other legal issues that might apply.
If a photo is CC BY but contains a person's face, you still cannot use it in advertising without that person's permission — that is a right of publicity issue, separate from copyright. If a song is CC BY-NC but samples another copyrighted song, you cannot legally use it commercially because the original copyright holder has not licensed it. If a photo contains a trademark (a logo, brand name), using it in a way that suggests endorsement can be trademark infringement, regardless of the CC license.
The license also does not cover patents. If software is CC BY but uses a patented algorithm, the patent holder can still sue you for using it, even though the copyright is licensed. Always check whether the work itself is free of other legal claims before you use it.
Putting your own work under a Creative Commons license
If you create something and want to share it under a Creative Commons license, you do not need permission from anyone. You own the copyright automatically, so you can choose which license to apply.
Go to creativecommons.org/choose and answer a few questions: Do you want to allow commercial use? Do you want to allow modifications? Do you want derivatives to use the same license? The tool will generate the correct license for you. You then add the license badge and a link to the license text to your work — on the photo's metadata, in the article footer, in the video description, or in the software's README file.
Be clear about what you are licensing. If you release a photo under CC BY, you are licensing only the photo itself, not any people in it or any copyrighted material visible in the background. If you release code under CC BY-SA, you are licensing the code you wrote, not any libraries or dependencies it uses.
Frequently Asked Questions
Can I use a Creative Commons photo in a commercial project?
It depends on the license. CC BY and CC0 allow commercial use. CC BY-NC, CC BY-NC-SA, and CC BY-NC-ND do not. CC BY-ND and CC BY-SA allow commercial use but have other restrictions. Always check the specific license before you use the work commercially.
Do I have to credit the creator if the license says CC0?
No. CC0 means the creator has waived all rights, including the right to be credited. You can use it however you want with no attribution. That said, crediting the creator is still good practice and helps others find their work.
What happens if I use Creative Commons work without following the license?
You are violating the license agreement, which is a legal contract. The creator can sue you for damages, just as they could for copyright infringement. The amount varies, but it can be substantial. Always follow the license terms.
Can I change a Creative Commons work and release it under a different license?
Only if the original license allows modifications and does not require ShareAlike. CC BY and CC0 allow this. CC BY-SA requires you to use the same license. CC BY-ND and CC BY-NC-ND do not allow modifications at all.
Is Creative Commons the same as public domain?
No. Public domain means copyright has expired or been waived entirely — nobody owns it. Creative Commons licenses mean someone still owns the copyright but has granted specific permissions. CC0 is the closest to public domain, but the creator retains the legal right to be credited if they choose.
