Free stock photos for commercial use

Why this matters

A free download button does not mean unrestricted use. Commercial use, attribution, modification, redistribution, API indexing and thumbnail display can each be governed by different rules. RightsGraph separates those signals so creators can make better decisions before using an image in a website, blog post, presentation, social campaign or AI-assisted workflow.

Many creators learn this the hard way — receiving takedown notices months after publishing, or discovering that their "free" image library violates platform terms. The time to verify is before you publish, not after.

Safer source types

• Public-domain museum collections: The Met Open Access (CC0, 490,000+ images), Smithsonian Open Access (CC0, 4.9M+ assets).
• Government archives: Library of Congress Free to Use sets, NASA Image and Video Library (public domain with brand restrictions).
• CC0 image collections: Sources with clear public-domain dedication and stable source pages.
• Creative Commons BY: Free to use with proper credit — verify the specific CC version (BY, BY-SA, BY-NC).
• Official APIs: Sources that document allowed metadata indexing, thumbnail display, and hotlinking terms.

What to check before using any photo

• Commercial-use permission: Does the license allow use in paid projects, products, or advertising?
• Attribution requirements: Is credit required? What format should the attribution take?
• Model and property releases: Does the photo include recognizable people, private property, brand logos, or trademarked designs?
• Modification rights: Can you crop, filter, overlay text, or combine with other images?
• Redistribution limits: Can you re-host the file? Can you include it in a template or product?

How RightsGraph helps

Every asset record on RightsGraph carries a license label, a quoted evidence snippet from the original source, the evidence URL, a thumbnail-permission status and a last-verified date. The platform links to original source pages — it does not proxy, re-host or redistribute files. This keeps license terms intact and respects source provider rules.

Recommended workflow

1. Start with a low-risk source category (public domain, CC0, or clearly documented CC BY).
2. Check the license label, commercial-use field, attribution field and risk level.
3. Open the original source page and verify current license terms directly.
4. Save the source URL and evidence URL with your project records.
5. Use the image according to current source terms — not according to assumptions.

FAQ

Can I use any free stock photo in a commercial project?

No. Commercial use requires verifying the specific license. CC0 and public-domain photos are safest. Creative Commons BY requires attribution. Some platforms allow free downloads but restrict commercial use, redistribution, or competing services.

What is the difference between commercial use and redistribution?

Commercial use means using a photo in a paid project, product, or advertisement. Redistribution means re-hosting, reselling, bundling, or building a competing gallery. A photo can allow commercial use while prohibiting redistribution.

Does RightsGraph provide the actual photo files?

No. RightsGraph is a metadata-first discovery platform. It links to original source pages where downloads happen. It does not proxy, cache, re-host or redistribute original media files.

What if a license is unclear?

If any license term is unclear — commercial use, attribution, thumbnail permission, or redistribution — treat the asset as review-required rather than safe. RightsGraph marks such assets with a medium or high risk level and hides thumbnails when permission status is unclear.
