Creators say the platforms own their work. That is not true, and the truth is both narrower and more useful. You keep the copyright to everything you make and post. What you hand over is a license, which is permission to use your work under a set of terms you agreed to when you made the account. Most major platforms use a license that reads roughly the same way. Almost nobody reads it, and the five rights inside it explain a lot of things creators find confusing later.
The first is a worldwide, royalty free license to host and display your work. Royalty free means exactly what it sounds like. The platform pays you nothing for the right itself, and nothing you earn from a creator fund or ad share changes the underlying grant. Worldwide means there is no country where the permission stops. There is also no meaningful clock on it while your account exists. That is the trade for free hosting, free bandwidth, and free distribution, and it is worth understanding as a trade rather than a theft.
The second is the right to sublicense and transfer. This is the one that surprises people. Sublicensable means the platform can pass your permission along to somebody else, such as a partner that syndicates content or a service that embeds it elsewhere. Transferable means the license goes with the company if the company is sold. You did not sign an agreement with a fixed set of people. You signed one with whoever holds the platform, now and later.
The third is the right to modify your work. Compression is a modification, which is why your careful color grade looks different after upload. Cropping is a modification, and it is how a vertical video ends up letterboxed or a horizontal one gets cut to fit a feed. Auto generated captions, auto generated thumbnails, and clips pulled from a longer piece all sit under this same permission. Most licenses cover derivative works in plain language. If you have ever wondered how a platform can chop your upload into a preview you never made, that is the answer.
The fourth is the right to run advertising around your work and to use it in promotion. Ads that play before or beside your video are sold by the platform, and unless you are in a program that shares revenue, that money is not split with you. Many licenses also permit use of your name, handle, and likeness to promote the service itself. That means your face can appear in a marketing push for the app without a separate contract or a separate check. This is legal and disclosed. It is simply disclosed in a place nobody looks.
The fifth is a survival period after you hit delete. Deleting a post removes it from your profile, but licenses generally allow copies to persist in backups for some window afterward. If other users downloaded, saved, or reposted your work before you deleted it, those copies do not disappear because you changed your mind. Some terms explicitly say the license continues for content that was shared with others. Delete is a strong word for what actually happens, and planning around that is more realistic than being angry about it.
Here is what none of this means. It does not mean you lost your copyright, because these licenses are non exclusive. Non exclusive is the most important phrase in the whole document. You can post the same video to four platforms, sell it to a brand, license it to a publication, cut it into a course, and register it with the copyright office. The platform got permission. It did not get ownership, and it cannot stop you from doing any of that.
So work like someone who owns the master. Keep original files off the platform and backed up somewhere you control, because a compressed download is not a master. Post the same work in more than one place so no single account is your entire archive. Read exclusivity language carefully in brand deals, since that is where creators actually give up rights that matter. Watch for any platform term that claims exclusive use, because that is a different animal from the standard license. Register the work that earns real money. The platform license is a fair trade for reach, and it stays fair as long as you never confuse posting with publishing.
