Free Stock Photos Aren't as Free as You Think: Unsplash, Pexels, and Pixabay Licensing Explained

Every day, millions of people download images from Unsplash, Pexels, and Pixabay for websites, social media, ads, and products. The pitch is simple: free photos, free for commercial use, no attribution required.

That's mostly accurate. But "mostly" is where people get into trouble. Each platform has specific restrictions buried in their terms of service, and the biggest risk isn't the license itself — it's what the license doesn't cover.

What the Licenses Actually Say

All three platforms allow commercial use. But they're not identical.

Unsplash grants an irrevocable, nonexclusive, worldwide copyright license to download, copy, modify, distribute, perform, and use images for free — including commercial purposes — without permission from or attributing the photographer. The license explicitly does not include the right to compile images to replicate a similar or competing service.

Pexels grants an irrevocable, worldwide, perpetual, non-exclusive, royalty-free right to download, use, copy, modify, or adapt content for commercial or non-commercial purposes. Same restriction: you can't compile content to create a competing service. Pexels also still has some older CC0 (Creative Commons Zero) content in its library, though newer uploads use the Pexels License.

Pixabay similarly allows free commercial and non-commercial use. Their license permits downloading, copying, modifying, and distributing content. Like the others, compiling content into a competing stock service is prohibited. Pixabay also explicitly allows its content to be used for AI and machine learning training, with an opt-out for contributors.

So far, so good. But the problems start with what these licenses don't guarantee.

Trap #1: No Model Releases

This is the biggest risk for commercial users.

When you use a photo of a recognizable person in an ad, product, or promotional material, you typically need a model release — written consent from that person authorizing commercial use of their likeness.

None of these platforms guarantee model releases. Anyone can upload a photo to Unsplash, Pexels, or Pixabay. The platforms don't verify that the photographer obtained consent from the people in the images. Their terms of service explicitly state that it's your responsibility to determine whether you need consent.

Pexels puts it clearly: "If your use of the Content is for commercial purposes, then it is likely that you will need consent or a license. Responsibility for determining whether permissions are needed always rests solely and exclusively with you."

This means: if you download a photo of a person from Pexels, use it in a Facebook ad, and that person sues for unauthorized use of their likeness, Pexels isn't liable. You are.

The rule of thumb: If a photo shows a recognizable person and you want to use it commercially, either confirm a model release exists (some platforms indicate this) or don't use it.

Trap #2: No Property Releases

The same issue applies to private property, trademarked objects, and certain famous buildings.

Examples that require property releases for commercial use: Apple products and distinctive electronics, designer furniture, Disney and LEGO products, the Chrysler Building in New York, the Burj Al Arab in Dubai, and many others.

Just because a photo of an iPhone sitting on a desk is available on Pixabay doesn't mean you can use it in an ad. Apple's product design is trademarked. You'd need a property release — and free stock platforms don't provide or verify them.

Trap #3: Anyone Can Upload Anything

This is the fundamental structural problem with free stock platforms. They operate as community-upload services where anyone can contribute images. The platforms require uploaders to confirm they own the rights, but they don't verify this claim.

This means images on these platforms can include:

Stolen photos. A photographer's copyrighted work uploaded by someone else without permission. If the original photographer uses reverse image search (or services like Pixsy or Copytrack) and finds their image on your website, they can send you a copyright infringement demand — typically $750 to $5,000 per image.

Screenshots or derivative works. Images that include copyrighted elements the uploader didn't have rights to.

AI-generated images. Increasingly common, and carrying their own set of licensing uncertainties.

The platform won't defend you. Their terms make this explicit: they disclaim all responsibility and liability for rights issues. You download and use at your own risk.

Trap #4: Not CC0 Anymore

Both Unsplash and Pixabay used to release content under Creative Commons Zero (CC0) — essentially public domain. That changed:

Unsplash switched from CC0 to its own Unsplash License in 2017. Pixabay switched from CC0 to its own Pixabay License in 2019.

The practical differences are small — both still allow free commercial use without attribution. But the custom licenses include restrictions that CC0 doesn't, particularly around compiling content and building competing services.

If you're working with older Unsplash or Pixabay content that was originally CC0, the CC0 dedication still applies to those specific images. But anything uploaded under the new license terms is governed by the platform-specific license.

Trap #5: The AI Training Clause

This won't affect most users, but it's worth knowing: free stock platforms increasingly permit (or don't prohibit) use of their content for AI model training.

Pixabay explicitly allows this with an opt-out for contributors. If you're a photographer whose images are on Pixabay, your work may be used to train AI models unless you opt out.

For users downloading images, this doesn't change your rights. But it does mean the images you download may also have been used to train AI generators — which creates an interesting loop where "free stock" and "AI-generated" content increasingly overlap.

When Free Stock Is Fine (and When It's Not)

Low-risk uses where free stock is generally safe:

Blog post illustrations where the image is decorative, not the product. Social media posts for personal or small-business use. Internal presentations and documents. Website background images that don't feature recognizable people or trademarked objects. Educational and editorial content.

Higher-risk uses where you should think twice:

Any advertising or promotional material featuring recognizable people. Product packaging or merchandise. High-visibility ad campaigns where a copyright claim would be embarrassing. Contexts where you need exclusive rights (stock content is non-exclusive by definition). Trademark applications (stock images can't be trademarked).

The Alternative: Paid Stock Platforms

Paid platforms like Shutterstock, Adobe Stock, and Getty Images charge money, but they offer something free platforms can't:

Verified model and property releases. Commercial images on paid platforms include confirmation that releases have been obtained. Indemnification. Most paid stock platforms will cover legal costs if a properly licensed image leads to an IP claim. Quality control. Submissions are reviewed before being accepted, reducing the risk of stolen or rights-encumbered content.

The cost of a stock subscription ($29-$199/month depending on platform and plan) is insurance against a $5,000+ copyright claim. For commercial work, especially client work, it's usually worth it.

The Smart Approach

Free stock photos are a genuinely useful resource — but only if you use them with eyes open.

For blog posts and social media: Free stock is fine for most uses. Avoid images with recognizable people if you're promoting a product or service.

For advertising and client work: Use paid stock with proper releases and indemnification, or create original content.

For any use: Don't assume a photo on a free platform is rights-clear just because the platform says so. The platforms disclaim all liability — which means the risk sits with you.
