Many of the most popular free image sites operate under licences that technically permit commercial use — but require you to credit the photographer. For a social post or a blog graphic, that is manageable. For a client's marketing campaign, product brochure, or advertising creative, attribution to a third-party photographer is often impractical or contractually prohibited. Knowing which sources genuinely do not require attribution is a meaningful time-saver.
The best sources for no-attribution royalty-free images
The most reliable platforms for royalty-free images with no attribution requirement include Unsplash, Pexels, and Pixabay — all of which operate under licences that explicitly waive the attribution requirement for commercial use. Unsplash's licence and Pexels' licence both permit use in commercial projects without crediting the photographer, though redistribution of the images themselves (as stock images) is not permitted. Pixabay operates under CC0, which is the most permissive option.
What 'no attribution required' does not mean
No attribution requirement does not mean no restrictions exist. Even under Unsplash or Pexels licences, you cannot resell the images as stock photography, use them in ways that imply endorsement by the people shown, or incorporate them into products primarily competing with stock photography platforms. For commercial advertising work, you should also check whether identifiable people in the images have model releases — both Pexels and Unsplash note that this is the photographer's responsibility, but verifying it before use in advertising is good practice.
Free stock images vs. paid for commercial work
For most marketing and content work, free no-attribution image libraries are entirely adequate. The gap shows up in specificity: free libraries are deep on lifestyle, nature, and generic business imagery but thin on specialised product, industrial, or highly polished commercial photography. If you need a specific image type that free libraries do not cover well, a paid service like Getty Images, Shutterstock, or Adobe Stock may be necessary — but for a large proportion of commercial content work, the free options are genuinely sufficient.
Finding the right image faster with a royalty-free asset finder
Searching multiple image libraries individually is time-consuming, especially when you need to cross-check licences. A royalty-free asset finder that lets you search across sources while filtering by licence type — including 'no attribution required' — reduces the research time significantly. The royalty-free asset finder at FileFeedback is filterable by asset type and licence, covering both free and paid image sources across 18 platforms.
“Checking attribution requirements takes two minutes. Discovering mid-campaign that you owe a photographer credit on a commercial billboard does not — and may require the whole asset to be replaced.”

Frequently asked questions
Can I use Unsplash photos in commercial advertising?
Yes, for most commercial uses including advertising. Unsplash's licence permits use in paid advertising campaigns. The main restrictions are that you cannot resell the photos as stock imagery and cannot use them in ways that portray identifiable people in a misleading or defamatory way. Model releases are the photographer's responsibility under Unsplash's terms.
Is Pexels free for commercial use without credit?
Yes. Pexels explicitly waives the attribution requirement for both personal and commercial use. You are not required to credit the photographer, though it is appreciated. The key restriction is that you cannot redistribute Pexels images as a competing stock photography product.
What is the difference between royalty-free and CC0 for images?
Royalty-free means you pay once (or access free) and do not owe additional royalties per use, but restrictions may still apply. CC0 (Creative Commons Zero) is a full public domain dedication with no restrictions at all — no attribution, no use restrictions, complete freedom of use. CC0 is the most permissive category.
Can I use free stock images in a client project without telling the client where they came from?
Generally yes, as long as the licence permits commercial use without attribution. You do not typically need to disclose the source to your client. However, for high-value or legally sensitive commercial projects, it is worth noting in your delivery documentation which images are licensed stock and providing the licence documentation if requested.
