Key takeaways
- Unsplash, Pexels, and Pixabay all offer photos free for commercial use with no required attribution — they're the safe defaults.
- Download and host images yourself; never hotlink, and never source "free" images from a general image search.
- Copyright-free is not risk-free: recognizable people in ads, trademarks, and logos in-frame need extra care.
The best free stock photo sites for commercial use are Unsplash, Pexels, and Pixabay. All three let you download high-resolution photos and use them in commercial projects — websites, marketing, client work — without paying or asking permission, and without legally required credit. The differences are in library character, search quality, and extra media types. Below: how they compare, what their licenses actually say, and the handful of traps that still catch people out.
License comparison
| Site | Commercial use | Attribution | Also offers | Library character |
|---|---|---|---|---|
| Unsplash Free | Yes | Not required, appreciated | Photos only | Artistic, editorial feel; strong search |
| Pexels Free | Yes | Not required, appreciated | Photos + free videos | Practical, business-friendly subjects |
| Pixabay Free | Yes | Not required | Photos, illustrations, vectors, video, music | Broadest media mix; quality varies more |
All three licenses share the same shape: free to use, modify, and distribute commercially; no permission needed; credit optional. All three also share the same core restrictions, which lead directly to the traps below. Licenses can evolve, so check each site's current license page for anything high-stakes.
The traps to avoid
1. Hotlinking
Embedding an image via the stock site's URL instead of downloading it is against the sites' terms and leaves your page dependent on their servers — if the URL changes or the image is removed, your page breaks. Always download and host the file yourself. It also lets you compress and resize the image, which your page speed will thank you for.
2. Recognizable people in advertising
A photo license covers copyright — it does not give you a person's right of publicity. Putting a recognizable stranger's face in an ad implies their endorsement of your product, which usually requires a model release regardless of where the photo came from. For commercial campaigns: prefer images explicitly marked as model-released, shoot your own, or crop/obscure faces. Editorial use (a blog illustration, like this one) is far more forgiving than advertising use.
3. Trademarks and products in-frame
Photos containing visible logos, branded products, or distinctive buildings can raise the same endorsement problem in ads. Scan the frame before using an image commercially.
4. Reselling unaltered images
All three licenses prohibit selling or redistributing the photos essentially unchanged — you can't bundle them into a stock pack or print them as-is on merchandise for sale. Significant modification or use as one element of a larger design (a poster, a website hero) is the intended use.
5. "Free" images from search engines
Image search results are not a stock site. Most indexed images are copyrighted, and "labeled for reuse" filters are unreliable. If an image isn't from a site with a stated license, treat it as unusable.
A safe workflow for using free stock
- Search Unsplash first for atmosphere and editorial quality, Pexels for business and lifestyle subjects, Pixabay when you also need illustrations, vectors, or video.
- Download the file and note the source URL and date in a simple spreadsheet — your paper trail if the image is ever questioned.
- Check the frame for faces, logos, and branded products before commercial use.
- Optimize before uploading: resize to display dimensions and compress. Editing and retouching is easy in the free browser photo editors we've reviewed.
- Credit the photographer when practical — not required, but it supports the ecosystem you're benefiting from.

Frequently asked questions
Can I use free stock photos for commercial projects?
Yes, from reputable sites like Unsplash, Pexels, and Pixabay. Their licenses permit commercial use — websites, ads, social media, products — without payment. What you generally can't do is resell the photos themselves unaltered or imply endorsement by people pictured.
Do I have to credit the photographer?
On Unsplash, Pexels, and Pixabay, attribution is appreciated but not legally required by the license. Crediting is good practice — it supports photographers and documents where the image came from if questions arise later.
Can I use photos with recognizable people in advertising?
Be careful. A photo license covers copyright, not publicity rights. Using an image of a recognizable person in an ad implies their endorsement, which typically requires a model release. For ads, choose images the site marks as model-released, or avoid identifiable people entirely.
Is hotlinking stock photos okay?
No. Hotlinking — embedding the image from the site's server URL instead of downloading it — violates most sites' terms and creates a dependency on their bandwidth. Always download the file and host it yourself.
Are free stock photos safe from copyright claims?
Mostly, on the major sites — but no site can guarantee every uploader owned what they uploaded. The practical defense: use established sites, keep a record of where and when you downloaded each image, and never use 'free' images scraped from search engines.
