Fair use can allow limited use of copyrighted material without permission, but it is not a blanket exemption for convenient borrowing. This guide compares fair use with permission and licensing, then gives creators a practical way to assess images, music, text, and video before publishing.
Overview
When you want to include someone else’s work in a post, video, course, book, advertisement, or product, you generally have two paths: rely on a legal exception such as fair use where it applies, or obtain permission through a license or written authorization. The safer choice depends on what you are using, why you are using it, how much you are taking, and what effect your use may have on the original market.
Fair use is a fact-specific doctrine most closely associated with United States copyright law. It is not determined by a single percentage, word count, attribution statement, or online “fair use checker.” Other countries may use different exceptions, such as fair dealing, quotation rights, educational exceptions, or specific parody rules. If your audience, business, or publication spans multiple countries, review the rules that may apply in each relevant jurisdiction. Our guide to international copyright protection provides useful context for that issue.
Permission is more predictable when you can identify the copyright owner and agree on the intended use. A license can define the media, territory, duration, audience, exclusivity, modifications, credit, and payment terms. For commercial campaigns, paid products, branded content, or high-visibility releases, a clear copyright license agreement is often more practical than accepting uncertainty.
How to compare options
Use this decision process before you publish:
- Identify the work and owner. Record the title, creator, source, publication date if available, and any license information. Do not assume that material found through a search engine, social platform, or stock-image preview is free to reuse.
- Define your purpose. Ask whether you are commenting on, criticizing, reviewing, teaching about, reporting on, parodying, or merely decorating with the work. A purpose connected to discussion or analysis may support a fair-use argument more strongly than use as an attractive background or substitute for an image you would otherwise license.
- Measure the amount used. Consider both quantity and qualitative importance. A short excerpt can still be significant if it captures the most recognizable or important part of a song, article, photograph, film, or illustration.
- Assess transformation. Explain what new meaning, message, context, or function your work adds. Changing a file format, adding a border, placing music under a montage, or resizing an image is not necessarily transformative.
- Consider market impact. Could your use replace the original, reduce demand for a license, or compete with an established permission market? A commercial use is not automatically infringement, and a nonprofit use is not automatically fair, but the economic context matters.
- Evaluate your risk tolerance. A personal commentary post and a national advertising campaign do not present the same practical exposure. Consider audience size, revenue, distribution channels, deadlines, and whether removal would cause significant harm.
If you cannot explain why your use needs the particular material, why the amount is limited, and what new purpose your work serves, permission may be the more efficient choice. Attribution is good professional practice, but credit alone does not replace permission or establish fair use.
Feature-by-feature breakdown
Images and artwork
Images are often used decoratively, which can weaken a fair-use position when the image is not the subject of commentary. A review that displays a limited screenshot or cover image while analyzing it may present a different question from a blog that uses a photographer’s image as a page banner. Check whether the image is public domain, covered by a stated Creative Commons or stock license, or available directly from the creator. Keep a copy of the license terms and note any attribution or modification requirements.
Music
Music can involve separate rights in the musical composition and the sound recording. Using a short clip does not automatically make the use fair, especially if the excerpt is the memorable part of the recording or functions as entertainment rather than commentary. For music in videos, podcasts, courses, livestreams, and advertisements, a purpose-built license or platform-cleared library may reduce uncertainty. Platform detection systems may also flag a use even when you believe it is legally defensible; a copyright claim on YouTube or another service is not the same thing as a final court determination.
Text and quotations
Quotation is more defensible when the excerpt is necessary to discuss the author’s words and is surrounded by your own analysis. Copying text to provide a free substitute for the original, assembling a collection of excerpts, or reproducing an article for convenience creates greater risk. Track the source and use only the amount needed for your stated purpose. For website pages, product descriptions, and blog material, see the guide to copyright for website content.
Video and film
Clips used for criticism, commentary, teaching, or reporting should be tied directly to the point you are making. Avoid using long passages merely to increase entertainment value or fill time. Add your explanation, interruption, comparison, or analysis where appropriate, and preserve evidence showing how the clip supports the discussion. A clip that is technically short may still be problematic if it reveals the core of the work or serves as a substitute for watching it.
Public domain and openly licensed material
Public domain is not the same as “available online.” Confirm that the work is genuinely public domain in the place where you will use it and check whether a particular recording, translation, restoration, or adaptation carries separate rights. Open licenses also have conditions. Read the exact license, retain the license page or file, and comply with requirements concerning credit, noncommercial use, share-alike terms, or modifications.
Best fit by scenario
- Critique, review, or commentary: Fair use may be worth analyzing when the material is directly relevant, the excerpt is limited, and your work adds substantial discussion. Keep the borrowed material subordinate to your original analysis.
- Commercial advertising or sponsored content: Permission or a negotiated license is usually the more controlled path. Define the campaign, platforms, territory, term, edits, and approval process in writing.
- Decorative website or social media use: Obtain a license, use public-domain material, or select an image with clear reuse terms. Do not treat a creator’s failure to include a watermark as permission.
- Education and online courses: Educational purpose can be relevant, but it does not automatically clear every image, article, song, or video. Limit access where appropriate, use licensed resources, and document why each excerpt is needed. Review the guidance on copyright for online courses.
- News, criticism, or reporting: Use only what helps the audience understand the event or subject. Separate factual reporting from unnecessary reproduction of the underlying creative work.
- Uncertain or high-value project: Ask the copyright owner for permission or consult a copyright lawyer before release. A written DMCA takedown notice is an enforcement tool for your own rights, not a substitute for clearing material you want to use.
When requesting authorization, describe the work, intended use, placement, audience, duration, territory, edits, attribution, and whether the use is commercial. A concise copyright permission letter can prevent later disagreement about what was approved.
When to revisit
Recheck your decision whenever the project changes. A use that seemed limited may become riskier if you add paid promotion, expand distribution, place it behind a subscription, license the finished work to a third party, or reuse the material in a different format. Revisit the analysis if the owner releases a licensing option, the platform changes its content rules, or you discover that the source was not authorized to grant permission.
Before publishing, save the source page, license, permission correspondence, screenshots, download date, and your fair-use reasoning. If you rely on an exception, write a short internal memo answering the purpose, amount, transformation, market effect, jurisdiction, and risk questions. If you receive a complaint, preserve the disputed version and related records rather than deleting evidence immediately. The copyright infringement evidence checklist can help organize documentation.
Finally, treat this guide as an educational workflow, not a guaranteed fair-use determination. Copyright law is fact-specific, and the answer can change with the country, work, audience, and business context. When the consequences are material, obtain tailored legal advice before release. For lower-risk projects, disciplined sourcing, clear licenses, limited excerpts, and careful records offer a practical foundation for responsible publishing.
