To tell if an image is copyrighted, start with the assumption that it is, then work through a short set of checks: look for a notice or watermark, run a reverse image search, read the metadata, and review the licensing terms on the page where you found it. Under federal law, copyright attaches automatically the moment an original image is saved, printed, or otherwise fixed in a tangible form, with no registration or © symbol required.1Office of the Law Revision Counsel. 17 USC 102 – Subject Matter of Copyright: In General So the real question is rarely “is this copyrighted?” It’s usually “can I confirm who owns it and whether I’m allowed to use it?”
Start From the Default: Assume It’s Protected
Copyright law protects “original works of authorship fixed in any tangible medium of expression,” and that sweeps in photographs, illustrations, digital art, and graphic designs.1Office of the Law Revision Counsel. 17 USC 102 – Subject Matter of Copyright: In General No paperwork. No symbol. No filing fee. The instant a photographer clicks the shutter or an illustrator saves a drawing, the work is protected.
Registration is a separate question. A copyright owner needs a registered copyright to file an infringement lawsuit in federal court over a U.S. work,2U.S. Copyright Office. Copyright in General (FAQ) and if they don’t register within three months of publication or before the infringement begins, they lose access to statutory damages and attorney’s fees.3Office of the Law Revision Counsel. 17 USC 412 – Registration as Prerequisite to Certain Remedies for Infringement None of that means an unregistered image is fair game. The absence of a registration is not the absence of a copyright.
Treating everything as protected until you confirm otherwise is the safe posture. The checks below help you confirm.
Look for a Copyright Notice or Watermark
The most visible clue is a copyright notice printed on or near the image: the © symbol, the year of first publication, and the copyright holder’s name. Notices have been optional in the United States since 1989, but many creators still attach one because it kills a common defense. When a proper notice appears on a copy you had access to, a court will not give any weight to an innocent-infringement claim.4Office of the Law Revision Counsel. 17 U.S. Code 401 – Notice of Copyright: Visually Perceptible Copies
Watermarks send the same signal. A translucent logo, name, or pattern laid over an image tells you someone considers it their property. Stock photo agencies watermark preview images specifically to block unauthorized use. If you see a watermark, the image is almost certainly copyrighted, commercially licensed, or both.
The reverse is not true. Most copyrighted images circulating online carry neither a notice nor a watermark. Assuming an image is free because it lacks a © is one of the most common ways people accidentally infringe.
Run a Reverse Image Search
When an image has no obvious ownership information, a reverse image search can trace it back to its source. Google Images, TinEye, and Bing Visual Search each let you upload a file or paste a URL, then scan the web for matching or similar images.
The results often reveal the original context. You might land on a photographer’s portfolio, a stock listing with pricing and license terms, or a news agency’s image library. Any of those results confirms the image is copyrighted and points you to whoever controls it. Finding the same image on a stock photography site is a strong signal that someone is actively licensing it.
Reverse image search has limits. It will miss matches when an image has been cropped, color-shifted, or otherwise altered, and it cannot tell you the legal status of an image directly. Use it as an investigative tool, not a verdict.
Check the Image’s Metadata
Digital images often carry embedded data with copyright information. Two common standards do the work here. EXIF stores technical details like camera settings and the date the photo was taken. IPTC holds descriptive and administrative fields, including the creator’s name, contact information, and explicit copyright status. On Windows, right-click the file and select “Properties.” On a Mac, select the file and choose “Get Info.” Image editors and free online metadata viewers show the full range of fields.
A copyright notice or creator name in the metadata is solid evidence the image is protected. Missing metadata proves nothing. Many social media platforms and websites strip EXIF and IPTC fields during upload, so an image pulled from a feed may have had its data wiped. The copyright survives the metadata.
Read the Licensing Terms on the Page
When an owner wants others to use their image, they attach a license spelling out what’s allowed. Finding license terms on the page where you sourced the image confirms both that the work is copyrighted and how you can use it.
Creative Commons Licenses
Creative Commons (CC) licenses let creators grant public permission while keeping their copyright. The six standard CC licenses are built from four conditions:5Creative Commons. About CC Licenses
- BY (Attribution): you must credit the creator.
- NC (NonCommercial): you can only use the work for noncommercial purposes.
- ND (NoDerivatives): you cannot modify or adapt the work.
- SA (ShareAlike): if you modify the work, you must release your version under the same license terms.
Every standard CC license includes BY. An image labeled “CC BY-NC,” for example, is free to use as long as you credit the creator and don’t use it commercially. Ignoring the specific conditions is still infringement.
Stock Photo Licenses
Stock platforms sell images under two main models. A Royalty-Free license lets you pay once and use the image across multiple projects without additional fees. A Rights-Managed license charges per use and may restrict the image to a specific publication, region, or time period. Terms are spelled out where you buy the image, and they matter. Using a Royalty-Free image outside its scope, like reselling it or placing it on merchandise the license doesn’t allow, is infringement even though you paid for access.
Search Copyright Office Records
The U.S. Copyright Office maintains a searchable database of registered works, the Copyright Public Records Portal. It covers registrations and related documents from 1870 to the present, split across several collections including the Copyright Public Records System (1898–1945 and 1978–present) and the Virtual Card Catalog (1870–1977).6U.S. Copyright Office. Search Copyright Records: Copyright Public Records Portal
Finding a registration confirms both copyright status and ownership. Not finding one proves nothing, since millions of copyrighted works are never registered. The database is most useful for older works where you need to verify whether copyright was properly renewed, a requirement for works published before 1978.
When an Image Really Is Free to Use
An image in the public domain can be used by anyone for any purpose without permission or payment. Images reach the public domain in a few ways.
Expired Copyrights
As of 2026, any work published in the United States in 1930 or earlier is in the public domain, and each January 1 another year loses protection as 95-year terms expire. For images created by an individual after January 1, 1978, copyright lasts for the author’s life plus 70 years. For works made for hire, the term is 95 years from publication or 120 years from creation, whichever is shorter.7Office of the Law Revision Counsel. 17 USC 302 – Duration of Copyright: Works Created on or After January 1, 1978
Works published without a copyright notice before March 1, 1989, may also have entered the public domain, though the outcome depends on the exact publication date and whether the copyright was renewed. Those rules are complicated enough that you should research the specific work rather than assume.
U.S. Government Works
Images created by federal government employees as part of their official duties are not eligible for copyright and belong to the public domain.8Office of the Law Revision Counsel. 17 USC 105 – Subject Matter of Copyright: United States Government Works NASA photos, military imagery, and many images in the Library of Congress digital collections fall into this category.9Library of Congress. Free to Use and Reuse Sets One distinction to watch: works created by government contractors or grantees may still be copyrighted, even when they were funded with taxpayer money.
Fully AI-Generated Images
The U.S. Copyright Office has taken the position that material generated entirely by artificial intelligence is not copyrightable. In a 2025 report, the Office concluded that copyright does not extend to purely AI-generated content or to material where the human user did not exercise sufficient control over the expressive elements. Text prompts alone, the Office found, are unlikely to satisfy the human authorship requirement.10U.S. Copyright Office. Copyright and Artificial Intelligence, Part 2: Copyrightability Report A fully AI-generated image sits outside copyright protection, but an image where a human artist made meaningful creative choices using AI as a tool could still qualify. The line is developing quickly.
When Fair Use Might Cover You
Even when an image is clearly copyrighted, fair use is a legal defense that allows limited use without the owner’s permission. It covers uses like criticism, commentary, news reporting, teaching, and research.11Office of the Law Revision Counsel. 17 USC 107 – Limitations on Exclusive Rights: Fair Use It does not mean “I’m not making money from it, so it’s fine.” Courts weigh four factors:
- Purpose and character of your use. Commercial use weighs against fair use; transformative use, where you add new meaning or purpose rather than just reproducing the original, weighs in your favor.
- Nature of the copyrighted work. Factual images (a news photo) get more leeway than creative ones (an art photograph).
- Amount used. Less is better, but using the “heart” of the work can count against you even when the portion is small.
- Market effect. If your use substitutes for the original or undercuts the creator’s ability to license it, this is the factor courts care about most.
No single factor is decisive, and fair use is evaluated case by case. People get into trouble by leaning on one factor, like being nonprofit, while ignoring the others. If you’re relying on fair use for anything commercially significant, get a legal opinion first. The defense is powerful but unpredictable.
What It Costs to Guess Wrong
The financial exposure for image infringement catches people off guard. If the copyright owner registered their work in time, they can elect statutory damages instead of proving actual losses. A court can award between $750 and $30,000 per work infringed, and for willful infringement that ceiling jumps to $150,000.12Office of the Law Revision Counsel. 17 U.S. Code 504 – Remedies for Infringement: Damages and Profits If you can prove you genuinely had no reason to believe your use was infringing, the floor drops to $200.
Stripping watermarks or other copyright information before using an image carries separate liability under the DMCA’s provisions on copyright management information. Those penalties attach per violation rather than per work, so damages add up fast when the same stripping practice is applied across many images.
For smaller disputes, the Copyright Claims Board (CCB) offers a streamlined alternative to federal court. The CCB can award up to $30,000 in total damages per proceeding, or $5,000 in its smaller-claims track.13U.S. Copyright Office. Damages – Copyright Claims Board Handbook The process is faster and cheaper than federal litigation, which means owners who once wouldn’t have bothered suing over a single image now have a viable enforcement path. Running the checks above before you publish is much cheaper than answering a claim after.
