Using a free stock photo in a client project, an ad, or a product you sell sounds risky. But it is completely legal — as long as you pick the right source and understand what the licence actually permits. Most creators get this wrong because they conflate "free" with "unlicensed."
Here is the definitive guide to using free stock photos commercially without getting into trouble.
What "Commercial Use" Actually Means
Commercial use means the image is used in a context where money changes hands — or where the primary purpose is to promote a product, service, or brand. Examples include:
- Advertisements (social media ads, Google Ads, billboards)
- Product packaging or labels
- Client websites and marketing materials
- Monetised YouTube videos and blog posts
- Merchandise and print-on-demand products
By contrast, "editorial use" covers news reporting, education, and commentary — contexts where the image is illustrative rather than promotional.
The Safest Free Sources for Commercial Use
Pexels
The Pexels licence is one of the most permissive available. You can use photos and videos for free, commercially, without attribution, and modify them however you like. The only restrictions: you cannot sell the photos as-is, and you cannot imply endorsement by the people in the images.
Pixabay
Pixabay's Content Licence is similarly broad. All content can be used commercially, without attribution, including in advertising. The same restrictions apply — no reselling raw files, no implying endorsement.
Unsplash
Unsplash's licence allows free commercial use without attribution. However, it explicitly prohibits using Unsplash photos to create a competing stock photo service. For most use cases it is fine.
What You Cannot Do (Even with Free Licences)
- Sell the raw files — You cannot package and resell stock photos as a stock photo product.
- Imply endorsement — If a photo shows a real person, you cannot use it in a way that implies they endorse your product or hold views they may not hold.
- Use sensitive context without a model release — Using a photo of an identifiable person in an ad for a medical product, a political campaign, or anything controversial requires a model release. Pexels and Pixabay do not guarantee releases for all images.
- Use as a trademark or logo — You cannot register a stock photo as a trademark.
Model Releases and Property Releases
This is where most people stumble. A model release is a signed consent form from the person in the photo. Without one, using a photo of an identifiable person in a commercial context — particularly in a way that could be seen as endorsement — is legally risky.
Pexels and Pixabay do not require contributors to submit model releases, and they do not guarantee that releases exist. For low-risk commercial use (a lifestyle image on a homepage), the practical risk is very low. For high-risk use (a medical ad, a politically sensitive campaign), you should either verify a release exists or choose images without identifiable faces.
