Note that free programs generally are not free of intellectual property protections. Just as websites may be free to access, but still covered under copyright, simply because a software is free to download, run or play, does not mean that it is in the public domain or freely licensed in a way that is compatible with Commons. For those that are under a free license, you must still conform to the terms of the particular licence, which usually means you must publish your derivative work under the same licence, and correctly attribute the original authors or owners. However, screenshots of programs with a command-line interface may fall into public domain. See {{PD-text}} for more information.

Note, this does not prevent you from uploading works created using non-free software, it is not subject to the copyright of the software itself in most cases. This is especially true for fonts, which in some cases are considered programs.

• Use a free program with a completely free skin. (A KDE Program using Breeze theme is an example.) If you are using an operating system with a non-free theme (like Windows), make sure it fits something like {{PD-ineligible}}, e.g. has only flat-colored backgrounds and buttons and no complex icons. See Commons:独創性の水準 for examples of images, or image modifications or other actions considered trivial or non-trivial in different countries.

Common free web browsers include Mozilla Firefox, Chromium, Konqueror, and GNOME Web. Screenshots of these browsers displaying free content should be permissible, so long as they do not include copyrightable elements of a proprietary operating system, other proprietary software or non-free user interface customizations. The Firefox icon before Firefox 3.6 is non-free, so it must not be included in screenshots (internal logo files from Firefox 3.6 to 12 are under the Mozilla tri-license and from Firefox 13 are under Mozilla Public License 2.0, although trademarked, so are acceptable where hard to avoid). GNU IceCat, a rebranded Firefox-based browser, is unencumbered by this problem, but may show small non-free logos under certain configurations, which should be replaced.

Google Chrome has caused conflicts; even though, besides its logo, there are no immediately visible differences between Chrome and its open source arm Chromium, it has been asserted that Google Chrome itself is non-free because its official binaries are subject to a non-free Google Chrome Terms of Service which overrides the open source terms of its base source code. Deletion discussions have gone both ways.

Although Wikipedia is often a component of free screenshots, there have been issues.

• Most Wikimedia logos were previously subject to a proprietary license, but this changed when they were freed, in 2014.
• If the screenshot contains images or icons with free licenses with requirements, you have to honor them, such as by listing them and their authors and licenses, which may be other than Creative Commons Attribution-ShareAlike.

Although much of Android is open source software, this does not apply to Google software or their icons. Additionally, many smartphones do not include the "stock" Android user experience, but one specific to the company (such as Samsung Experience/One UI, previously TouchWiz and Huawei EMUI). These aspects are copyrighted by the maker of the phone, and screenshots showing portions of these interfaces (such as home screens) are not free.

As for the Apple iOS, per this failed undeletion request, the iOS software license agreement doesn't allow you to use {{APSL}} or other free licenses, hence unless if developers of a particular iOS app said to use their own free license (even so, you should cut the Apple-designed GUIs, i.e. drop-down list items, the "Home" buttons (either float or machinery)), they're violating our License policy.
