How to Stop Customers Sharing Your Download Link
You cannot stop a file being copied. What you can control is who gets access, for how long, and what happens when a link travels — here is how to choose.

Start with the honest version, because every page about this subject starts with a lie.
If someone can open your file, they can copy it. Screenshots, re-recording, re-uploading, a friend's USB stick. No protection scheme changes that, and any product claiming otherwise is selling you a feeling.
What you can actually control is narrower and more useful: who is allowed in, for how long, and what it costs them to pass it on. That is where every real decision lives, and it is enough to change the outcome for most creators.
The short version
- Nothing prevents copying. Stop looking for that and spend the effort on access.
- Three levers do the work: cap the unlocks, expire the link, and make access attributable.
- Friction is the real mechanism. Every extra step removes some casual sharing.
- Expiry is the strongest and most under-used lever — it is also what makes a drop feel like a drop.
- Decide your position on purpose: tight control and wide distribution are both valid, and mixing them gives you the worst of both.
Why "sharing" is usually the wrong thing to be afraid of
Before defending against it, work out whether it is actually a problem.
The casual forward. One buyer sends it to one friend who was never going to pay. You have lost nothing, because that friend was not a customer. Chasing this is how creators end up with protection that annoys the people who did pay.
The deliberate re-seller. Someone buys once and uploads your file somewhere it competes with you. This is the real threat, it is rarer than the first, and it is worth actual effort.
The accidental leak. A shared drive, a forwarded email, a link in a group chat that keeps getting passed around. This is the one that quietly costs the most, and it is the one that caps and expiry solve.
Most of the fear is about the first case. Most of the damage is in the third.
Lever one: cap the number of unlocks
Instead of "this link works for anyone who has it", make it "this link works this many times".
A link capped at 100 unlocks behaves completely differently from an uncapped one, even though both are just a URL. The capped one has a natural end. It also creates the thing that makes buyers move: if a hundred people are getting in and there are more than a hundred who want to, the hundred-and-first person has a reason to buy now rather than later.
Where a cap beats a lecture
Telling buyers "please do not share this" is a request. A cap is a fact. People respect facts and ignore requests, and you do not have to be the one policing it.
This is also the honest answer to the question at the top of this page. You are not preventing the file from being copied. You are making the link finite, which is the part you actually own.
Lever two: expire it
An expiry date is the single most effective lever, and almost nobody uses it.
A link that dies on Sunday is worth sharing on Saturday and worthless on Monday. That is not a limitation; it is the product. Limited drops sell precisely because the window is real, and the moment the window closes, passing the link on stops being a threat at all.
Three ways to set it, for three different situations:
| Situation | Setting | What it does |
|---|---|---|
| A launch, a release, an event | Fixed date | Creates urgency, and ends distribution automatically |
| Steady selling, want a safety net | Expiry well in the future | Nothing changes day to day; the link cannot circulate forever |
| A time-sensitive deliverable | Days, not weeks | Matches how long the content is relevant |
The failure mode is the opposite of what people expect: creators leave links permanent because they are afraid of losing a future sale, and end up with a permanent URL circulating in group chats long after the launch has been forgotten.
Lever three: make access attributable
You cannot identify a leaker, but you can make the file carry a mark that tells you which copy it was — and knowing that is a surprising deterrent on its own.
The practical versions, in order of effort:
- A name in the file. Personalised covers, a footer, a slide. Cheap, visible, and it makes the buyer feel the copy is theirs rather than a generic file.
- A per-buyer detail. A version number or an order reference somewhere in the content. Nobody wants to be the person whose order number is on the file that leaked.
- A visible unique watermark. Strongest deterrent, most work, and it can be annoying enough to hurt the experience for honest buyers.
For most creators, the first is the right level: it costs nothing, it discourages the casual forward, and it has a second benefit — personalised files feel more valuable than the same file sent to everyone.
What watermarking does not do
It does not stop re-recording, re-typing or re-shooting. A determined person will strip it. It changes the behaviour of the ninety per cent who are not determined, which is the only thing any of this changes.
What to do when a file leaks anyway
It will, eventually, if the product is worth leaking. Three steps, in order:
- Check whether it matters. A copy in a private Discord among people who were never going to buy costs you nothing. A copy competing with your own link costs you sales.
- Close the open door first. If the leaked copy came from a live link, expire or cap it before chasing anything else. The leak is usually a symptom of a link with no limits, not of a malicious buyer.
- Use it as information. What leaked, how fast, and who had access tells you whether you were underpricing, over-distributing, or selling to an audience that does not value the thing.
The response that wastes the most time is chasing individual infringements for a product that sells at £15. The response that works is making the next link harder to pass on.
Decide your position on purpose
There are two coherent strategies here, and both are legitimate.
Wide distribution. Low price, no caps, no expiry. You are optimising for reach and treating sharing as marketing. This works when the product is cheap, the audience is large, and your real value is in the next product or the service behind it.
Tight control. Higher price, capped, expiring, personalised. You are optimising for revenue per buyer and treating the link as the product. This works when the content is scarce, the audience is small, or the buyer is a business.
What does not work is mixing them by accident — pricing low and protecting hard. That gives you the reach of a cheap product with the friction of a locked one, and buyers experience it as a nuisance rather than a bargain.
