Should I allow adaptations?
Allow adaptations unless you need the work to stay exactly as you made it. That is the whole decision. A Creative Commons license without the NoDerivatives condition lets anyone remix, translate, or build on what you publish. ND blocks that outright. Choose BY or BY-SA, state the version as 4.0, and mark the work clearly. The rest is detail.
What Happens When You Allow Adaptations
When you pick a license that permits adaptations (CC BY, CC BY-SA, CC BY-NC, or CC BY-NC-SA) you give the public permission to modify your work and share the result. The adapter licenses their own contribution. Your original stays under the license you chose. Reusers must attribute you, indicate that changes were made, and keep the same terms if ShareAlike applies.
Translation is normally an adaptation. Under the 4.0 legal code, synchronising music with a moving image is expressly Adapted Material. The adapter carries the legal responsibility for their version, not you.
What Reuse Looks Like in Practice
Imagine a photographer who publishes an image under CC BY. A designer downloads it, crops a section, adds text, and includes it in a poster for a commercial client. That is permitted. The designer attributes the photographer, marks the changes, and the client displays the poster. The photographer gets visibility and a credit line.
Now put the same image under CC BY-ND. The designer can still download it and display it unchanged in the poster. They cannot crop, overlay text, or combine it with other elements. The image must appear exactly as the photographer supplied it. If the designer wants a cropped version, they need separate permission.
What the NoDerivatives Condition Actually Blocks
An ND license permits sharing the unchanged work, including commercial sharing. It does not permit sharing an adapted version. A reuser may create an adaptation for private use but may not distribute it under the license. The 4.0 definition of Adapted Material is precise: converting a PDF to plain text, on its own, does not count as an adaptation. Whether cropping, excerpting, or editing qualifies depends on the copyright law that applies. There is no single rule.
Allow adaptations and your work enters a reuse ecosystem where it can be corrected, localised, and improved. Apply ND and it stays fixed. That is the trade-off.
Compatibility and Reversibility
Allowing adaptations creates compatibility with other works. A video editor can combine your CC BY footage with CC BY-SA footage from another creator, but the combined work must use BY-SA if that is the more restrictive license. The official compatibility list from Creative Commons controls which licenses can be mixed. An ND work cannot be legally combined into an adaptation without separate permission. For a collaborator, that is a dead end.
Reversibility works one way. Once you license a work under BY or BY-SA, you cannot revoke the permission for someone who already received it while complying with its terms. You can stop distributing the work or offer it under other terms later. Existing compliant copies remain usable. Applying ND is the only way to prevent downstream adaptation from ever happening.
| Licence Condition | Adaptation Allowed? | What Reuser May Do | What Reuser May Not Do |
|---|---|---|---|
| CC BY 4.0 | Yes | Share adapted work commercially or non-commercially; attribute licensor; indicate changes | Omit attribution or imply endorsement |
| CC BY-SA 4.0 | Yes, with ShareAlike | Share adapted work under BY-SA or a compatible licence; attribute; indicate changes | Apply a more restrictive licence to the adaptation |
| CC BY-ND 4.0 | No | Share unchanged work; create an adaptation for private use only | Share the adapted version |
| CC BY-NC 4.0 | Yes, non-commercial only | Share adapted work for non-commercial purposes; attribute; indicate changes | Use the adaptation commercially |
| CC BY-NC-SA 4.0 | Yes, with ShareAlike and NC | Share adapted non-commercial work under BY-NC-SA or compatible; attribute; indicate changes | Use commercially or apply a different licence |
| CC BY-NC-ND 4.0 | No | Share unchanged work for non-commercial use only | Share any adaptation or use commercially |
The Practical Creator's Decision
For maximum reach and reuse, allow adaptations. A license that permits them makes your work available for translation, editing, and remixing across borders and platforms. Pick this if you publish open educational resources, if you want your photographs seen in as many contexts as possible, or if your music needs to be synchronised with video projects.
For control over the message (a final report that must not be selectively excerpted, a piece of opinion writing that should appear only as you wrote it) apply the ND condition. You still get distribution and credit. The work stays intact. The cost is losing every reuse that requires a change. Most reusers who would have adapted your work simply move on to something else.
What Goes Wrong Most Often
A common failure is applying ND out of fear that someone will misuse the work, then wondering why nobody uses it at all. Another common failure is applying BY-SA and assuming any two SA-licensed works are compatible. They are not. The official compatibility list is the only authority. Check it before you combine material from different sources.
Common Questions
Can I change my mind and remove the adaptation permission later?
No. Once a Creative Commons license has been applied and someone has received the work in compliance with its terms, that permission is irrevocable. You can stop distributing the work or reissue it under a different license, but existing compliant copies remain usable under the original terms.
Does allowing adaptations mean I lose copyright in my work?
No. You retain copyright. The license grants specific permissions in advance. The adapter's rights cover only their contribution. Your original work remains your copyright, and the license does not transfer ownership.
If I allow adaptations, can someone use my work in a way I disagree with?
Yes, within the license terms. A CC license does not let you control the message or the context of the adaptation. The adapter must attribute you and mark changes, but they do not need your approval for the content of the adaptation.
What counts as an adaptation under 4.0?
Translation is normally an adaptation. Synchronising music with a moving image is expressly Adapted Material in the 4.0 legal code. Cropping, excerpting, or combining may or may not be, depending on applicable copyright law. Format-shifting alone is not an adaptation.
Can I allow adaptations for some people but not others?
Yes. You can offer the work under a public CC license that permits adaptations, and separately grant permission to a specific person to use it under different terms. Dual licensing is permitted. The public license remains in effect for everyone else.
