Should I watermark the file my customer paid for?

Not visibly. Use a small footer with their email or order number instead. A logo stamped across a paid file makes the product feel unfinished.

Do watermarks stop people copying files?

No. Anyone determined can remove one. They work as a deterrent, because most people will not share a file carrying their own email address.

Should I watermark my preview images?

Yes, always. Previews are public, and without a mark somebody can simply download the sample instead of buying the product.

Do selling platforms add watermarks automatically?

Some can stamp a buyer identifier into a PDF for you. Check whether yours does before you build the process by hand.

Should I watermark photos I sell?

Watermark the previews every time. Leave the delivered image clean, unless the licence you sold is preview-only.

Should I watermark my digital files?

Watermark previews, not the product

Watermark your previews, not the file the buyer paid for. A visible logo across a paid download makes the product feel cheap, and the buyer paid to be rid of it. The middle ground most sellers use is a small footer carrying the buyer’s email or order number.

Preview images on the product page should be watermarked, so nobody can simply take the sample.

The middle ground

A small footer on each page with the buyer’s email or order number. Quiet, and enough to discourage resharing.

This is what most experienced sellers do, and complaints about it are rare.

When a visible watermark is right

Free samples and lead magnets, where the point is to advertise. And preview versions sent out for review.

Never on the paid file, unless the licence specifically restricts how it may be used.

It is not protection

A watermark can be removed by anybody who wants to. It is a deterrent, not a lock.

Do not let it become the reason your product is worse to use.
