Non-copyrighted images are pictures you can legally use without asking permission, and they generally come from three places: works old enough that copyright has expired, works created by the U.S. federal government, and works whose creators have released them under a license (like CC0 or the terms used by sites such as Unsplash and Pexels) that lets anyone use them. The catch is that “free to find” and “free to use” are not the same thing. Almost every image online is copyrighted the moment it’s created, whether or not it carries a © symbol.1U.S. Copyright Office. What is Copyright Knowing which licenses grant real permission, where those images live, and how to verify a license before you download is what keeps you on safe ground.
What “Non-Copyrighted” Actually Means
Federal law gives the creator of an image exclusive control over reproducing it, distributing it, and making new works based on it.2Office of the Law Revision Counsel. 17 U.S. Code 106 – Exclusive Rights in Copyrighted Works Those rights exist automatically. Registration with the Copyright Office isn’t required for protection, though it unlocks the ability to sue and collect statutory damages.3U.S. Copyright Office. Copyright in General (FAQ) Using a protected image without permission can expose you to statutory damages ranging from $750 to $30,000 per work, and up to $150,000 if the infringement is willful.4Office of the Law Revision Counsel. 17 USC 504 – Remedies for Infringement: Damages and Profits
When people say “non-copyrighted,” they mean one of two situations: the image has no copyright at all, or the copyright holder has granted permission broad enough that ordinary use requires nothing from you.
Public Domain
A public domain image carries no copyright restrictions. You can copy it, edit it, sell it, or use it in an ad without asking anyone. An image reaches the public domain in one of three ways.
First, the copyright may have expired. As of January 1, 2026, all works first published in the United States before 1930 are in the public domain under the 95-year term set by the Copyright Term Extension Act.5Duke University School of Law. Public Domain Day 2026
Second, the work may never have been eligible. Federal law excludes works of the United States Government from copyright, which is why NASA photos, USGS maps, and similar federal content are generally free.6Office of the Law Revision Counsel. 17 USC 105 – Subject Matter of Copyright: United States Government Works “U.S. government work” means something created by a federal employee as part of their official duties. Contractors, grantees, and state or local governments don’t fall under this rule, and federal agencies sometimes host third-party content that remains copyrighted.7NASA. Guidelines for Using NASA Images and Media
Third, the creator may have voluntarily dedicated the work to the public domain.
Creative Commons Licenses
Creative Commons (CC) licenses let creators keep copyright while granting the public permission to use the work under stated conditions. There are six standard licenses and one public domain tool. The shorthand matters because misreading it is the most common way people end up in trouble.
- CC0 waives all rights. Use for anything, commercial or not, no attribution required. Functionally the same as public domain.8Creative Commons. CC0
- CC BY lets you use, modify, and commercialize the image with credit.9Creative Commons. About CC Licenses
- CC BY-SA is the same, but any modified version must be released under the same license.
- CC BY-NC allows use and modification with credit, but no commercial purposes.
- CC BY-ND allows sharing with credit, including commercially, but no alterations.
- CC BY-NC-SA and CC BY-NC-ND combine the non-commercial condition with the share-alike or no-derivatives rule and are the most restrictive of the set.
The NonCommercial restriction is where most people slip. A monetized blog, a product listing, a marketing email, an ad: all commercial. If you’re unsure whether your project qualifies, assume it does.
Royalty-Free Is Not Free
Royalty-free means you pay once and can reuse the image across multiple projects without paying per use. The photographer keeps the copyright, and the license carries limits on resale and redistribution. Paid stock sites like Shutterstock and Adobe Stock work this way. Worth knowing so you don’t confuse it with actually free.
Where to Find Images You Can Actually Use
Permissive Stock Photo Sites
Unsplash grants a broad, irrevocable license allowing commercial use, modification, and redistribution without attribution. The main restriction is that you can’t compile Unsplash images to build a competing stock service.10Unsplash. Terms and Conditions This is Unsplash’s own license, not CC0, so their terms govern.
Pexels allows free commercial and non-commercial use without attribution. You can’t sell unaltered copies as-is, and you can’t use images of identifiable people in an offensive context.11Pexels. Free Stock Photo and Video License
Pixabay offers a custom license permitting free use, modification, and commercial application without attribution. You can’t redistribute originals on competing platforms, and you’re responsible for any trademark or personality rights tied to what’s shown in the image.12Pixabay. Content License Summary Pixabay previously used CC0 for everything but switched to its own license, so older references to “Pixabay CC0” no longer reflect reality.
Government and Institutional Sources
NASA releases most of its imagery into the public domain under the federal government works rule. NASA logos and insignia are not public domain, and any image featuring a recognizable current employee or astronaut carries additional restrictions for commercial use.7NASA. Guidelines for Using NASA Images and Media
The Library of Congress maintains a “Free to Use and Reuse” collection of items the Library believes to be in the public domain, without known copyright, or cleared for public use. Individual items may still carry their own rights statements, so check each one.13Library of Congress. Free to Use and Reuse Sets
Wikimedia Commons hosts millions of public domain and CC-licensed files. Anyone can upload, and license tagging quality varies. Verify the stated license on the image’s description page rather than trusting a search summary.
Mixed-License Platforms
Flickr lets photographers tag their images with any CC license, so results range from fully open to heavily restricted. Use Flickr’s license filter to narrow to what fits your project. Google Images has a “Usage rights” filter under its search tools, but treat it as a starting point. That filter relies on metadata that can be outdated or inaccurate, so always confirm the license on the image’s source page.
How to Verify a License Before You Download
Filters get you into the right neighborhood. Verification confirms you’re actually at the address you think you are.
Use Platform Filters First
On Google Images, open Tools and set Usage rights to a Creative Commons option. On Flickr, use the license dropdown. On Unsplash, Pexels, and Pixabay, every image on the platform carries that site’s standard license, so no filtering is needed. Combine descriptive keywords with terms like “public domain” or “CC0” to surface results faster.
Trace the Image to Its Source
If you find an image on a blog or aggregator, run a reverse image search to trace it back. Google Images does this natively when you click the camera icon and upload a file or paste a URL. TinEye indexes billions of images and shows where else a photo has appeared, which helps identify the original photographer and confirm the license. This step catches a common problem: someone re-uploads a copyrighted image to a “free” site, and the listing looks legitimate until you find the original photographer’s watermarked version elsewhere.
Check the File’s Metadata
Digital images can carry copyright information inside their EXIF or XMP metadata. Fields like Creator, Copyright, and Rights Holder sometimes reveal the original owner even after a website strips other identifying information. Free tools like Jimpl or your operating system’s file properties viewer can display this data. It’s a clue, not proof: some cameras don’t record it, some formats like GIF don’t support it, and anyone with basic software can edit or remove it.
Attribution When It’s Required
CC0 and most stock-site licenses don’t require attribution. Every other Creative Commons license does. Creative Commons recommends four elements, sometimes called TASL: the title of the work (if one exists), the author’s name, a link to the source, and the specific license with a link to the license deed.14Creative Commons. Recommended Practices for Attribution
A workable format looks like: “Sunset Over the Rockies” by Jane Smith, via Flickr, licensed under CC BY 4.0. The placement can vary. A caption, a footer credit, or an image credits page all work, as long as a reader can identify the creator, find the original, and confirm the license.
Skipping required attribution voids the license. Your use then becomes ordinary copyright infringement with the exposure that comes with it.
What a Free License Doesn’t Cover
A clean copyright license doesn’t resolve every legal issue with an image. A few boundaries catch people off guard.
People in the Photo
Most states recognize a right of publicity that prevents you from using a recognizable person’s likeness for commercial purposes without their consent.15International Trademark Association. Right of Publicity This is a separate body of law from copyright. The photographer’s license (and any Creative Commons license) does not grant you the right to commercially exploit someone else’s face. A person can be “recognizable” through distinctive tattoos, clothing, context, or silhouette. For commercial use, you’ll want a signed model release. Pexels, Pixabay, and Unsplash flag this in their terms, but the responsibility falls on you, not the platform.
Property and Locations
Museums almost universally require a release for commercial use of images shot on their premises. Business interiors and distinctive private homes can trigger similar requirements, especially when the location is the subject rather than incidental background. Some publicly accessible spaces managed by private companies also restrict commercial photography.
AI-Generated Images
The U.S. Copyright Office has taken the position that purely AI-generated content, made by a machine without meaningful human creative input, is not eligible for copyright protection. A work combining human authorship with AI-generated elements may qualify, but only the human-authored portions receive protection.16U.S. Copyright Office. Copyright and Artificial Intelligence That might seem to put AI output outside copyright, but the picture is still developing. Some AI models were trained on copyrighted images, and outputs can resemble protected works closely enough to create infringement risk for the person who uses them. Treat AI-generated images with the same caution as any unlabeled image: check the source, look for license terms, and don’t assume “AI-made” means “free to use.”
Fair Use Is a Defense, Not a Source
Fair use lets you use copyrighted material without permission in narrow situations, weighed by courts on four factors: the purpose and character of your use, the nature of the original work, the amount used, and the effect on the market for the original.17Office of the Law Revision Counsel. 17 USC 107 – Limitations on Exclusive Rights: Fair Use It’s a defense you raise after being challenged, not a permission slip you rely on up front. When genuinely free images exist, relying on fair use for ordinary stock imagery isn’t a bet most people should take.
