How to protect photos from downloading when sending them to a client
Every photographer knows the discomfort: for the client to choose photos, you have to show them — but in showing them, you hand over control. What if the client downloads the full files, posts them on social media unedited and unattributed, or simply decides that since they already have them, they don't have to pay for "delivery"? That's a real risk, and it's protected against not by magic but by a few simple rules and the right tools.
In this article we go through methods of protecting photos at the selection stage — from the basic to the effective. Let's say right away: on the internet there is no absolute protection. If someone sees an image on a screen, they can take a screenshot. The goal, then, isn't to make theft impossible but to make it pointless — because what can be stolen is small, marked and useless.
The main rule: show previews, not originals
The most important decision is conceptual, not technical. At the selection stage the client doesn't need the full, edited files at maximum resolution. They only need them in order to decide which ones they want. For that, previews — photos at reduced resolution — are entirely sufficient.
That changes everything. If the client downloads a preview, they get an image fit for a small thumbnail, but not for print, not for a cover, not for serious use. Full quality — the kind you pay for — reaches the client only after the choice and the billing, in the final gallery.
That's why the worst possible solution is sending the client a package of originals (e.g. via WeTransfer or a cloud drive) "so they can choose". At that moment you hand over full quality before the conversation about editing and payment has even started. The choice should happen on previews.
Reduced resolution — the first and most important barrier
Reducing the resolution is the simplest and, at the same time, the most effective way to protect. A preview with a long edge of around 1000–2000 pixels looks great on a phone and computer screen, lets the client assess sharpness, composition and emotion — and at the same time is useless for professional print or large publications.
It's a real, physical limit on the file's value. You can't "make up" pixels that aren't there. A client who downloads such a preview gets an image suitable for viewing, not for exploitation. Combined with the fact that editing is still ahead of them anyway, a low-resolution preview effectively discourages "bypassing" your work.
Watermark — a signal, not a lock
A watermark is a semi-transparent caption or logo overlaid on the photo. It doesn't block downloading, but it serves two important functions:
- It marks authorship — anyone who sees the file knows whose photo it is and that it's a draft version.
- It discourages use — nobody posts a photo with a caption across the middle on their profile, so a raw preview loses its appeal as a "free" version.
A good watermark is visible enough to do its job, but subtle enough not to spoil the assessment of the photo. It's usually placed across the frame or discreetly in a corner with the studio's name. Combining a watermark with reduced resolution gives a preview that's for viewing and nothing more.
Access control — who sees the gallery and for how long
Another layer is limiting the access itself to the photos. Instead of sending files that live their own life once downloaded, you share a gallery over which you keep control:
- Access via a link rather than via download — the photos live in one place, not in dozens of folders on various devices.
- A time limit — the gallery active until a specified date, after which the choice closes. This both protects the files and mobilises the client to decide.
- Downloading disabled at the selection stage — the client views and marks, but doesn't download. They get the full files only in the final gallery.
Unlike a package sent by email, a gallery with access control stays "yours" — you can close it, replace it, restrict it. A file sent once as an attachment is beyond your control forever.
What to avoid
- Sending originals "for convenience". That's handing over the full value before the choice and payment. The most common and most serious mistake.
- Relying solely on disabling the right mouse button. That's an illusion of protection — it's bypassed in a second, and on a phone it doesn't even apply. The real barrier is resolution and a watermark, not a script blocking the menu.
- Confusing protection with hindering viewing. If the safeguards make it so the client can't comfortably view the photos, you lose twice over: you won't protect the originals anyway (because you're not sending them), and the client chooses more slowly and with frustration.
Technical protection isn't everything — the law is on your side too
It's easy to forget that besides technical barriers you also have legal protection. By force of copyright law you are the author of the photos, and the economic copyright stays with you until you expressly transfer it in a contract. A client who pays for a session usually gets a licence for a specified use — not the right to any use of the raw previews.
What this means in practice for protecting files:
- A raw, watermarked preview is not a "free photo for use". If the client uses it without your consent, they infringe your rights — regardless of the fact that they technically managed to save it.
- The contract is your hardest barrier. A clause about when and on what terms the client receives the final files, and that the previews serve only for the choice, sets expectations unambiguously and gives a basis should a dispute arise.
- Technical and legal safeguards work together. Resolution and a watermark make theft pointless; the contract and copyright make it risky. Only the combination of both gives real peace of mind.
This isn't about scaring clients with statutes — most of them act in good faith. It's about having ground under your feet in case of that minority, and, by the very setup of the process (previews instead of originals), simply not giving an opportunity for abuse.
Frequently asked questions about protecting photos
Won't the watermark spoil the client's assessment of the photo? No, if it's well done — fairly discreet but legible. The client still sees the composition, emotion and sharpness. And the awareness that it's a draft version is an advantage here, not a flaw.
What about a client who takes a screenshot anyway? They will — and they'll get a small, marked image at phone-screen resolution. Exactly the one they saw anyway. A screenshot doesn't bypass reduced resolution or a watermark, because it copies what's on the screen, and what's on the screen is precisely the protected preview.
Do I have to protect the final, edited photos too? The final files are already a product the client paid for — they have the right to use them within the licence. Here protection takes a back seat; what matters is rather a clear contract on the scope of use than technical locks.
Putting it all together
Effective protection of photos at the selection stage isn't one trick but layers that together make theft purposeless:
- The client views previews at reduced resolution.
- The previews carry a watermark with your brand.
- The photos live in a gallery accessed via a link, with the option to limit time and downloading.
- Full quality reaches the client only after the choice and the billing.
This is exactly how the process is designed in Pixchoose: you send the client a link to the gallery, they choose their favourite frames on watermarked previews, without access to the originals. The choice is convenient, and your full files stay safe until you decide to release them. This resolves the tension between "I have to show" and "I don't want to hand over" — because you show exactly as much as is needed for the decision, and not a pixel more.
Summary
You won't protect photos by making theft impossible — you'll protect them by making it not worthwhile. Show previews instead of originals, reduce the resolution, apply a watermark, and keep the photos in a gallery you control, instead of sending out files that slip from your hand the moment they're sent.
Release full quality — the kind the client pays for — deliberately, after the choice and the billing. Then the selection stage stops being the moment when you hand over the most valuable thing, and becomes what it should be: a convenient choice on safe previews.
