Image Watermark
What an image watermark is, when to add one to screenshots, and common mistakes.
An image watermark is a mark added to an image to show its owner, its source or its status. The name comes from paper watermarks, patterns pressed into paper during manufacture.
A visible watermark is text or a logo drawn on the image, usually semi-transparent and sometimes repeated across the whole area. An invisible, or digital, watermark is a signal hidden in the pixel data that software can detect later. It is designed to survive some editing, such as resizing or compression.
A watermark labels an image. It does not prevent copying, and a visible mark in a corner can be cropped out.
Visible vs invisible watermarks
| Visible | Invisible | |
|---|---|---|
| Seen by viewers | Yes | No |
| Purpose | Credit, status, deterrence | Tracking, proof of origin |
| Removal | Cropping or retouching | Requires heavy changes |
| Tools | Any editor | Specialized software |
Where watermarks are used
- Drafts and previews marked "DRAFT" or "CONFIDENTIAL".
- Photography and stock previews.
- Screenshots shared with a client before sign-off.
- Internal screenshots that should not be mistaken for public material.
How to watermark effectively
- Decide the purpose: credit, status or deterrence.
- Place the mark where it is hard to crop out, such as across the content, if deterrence matters.
- Keep opacity low enough that the screenshot stays readable.
- Use the same position and size across a series.
- Keep an unmarked original.
In Temposhot, the Documents editor's Text tool (T) adds a label to a page, and the PDF dialog can add page numbers and a cover page (Pro customization). Temposhot has no separate watermark feature.
Common mistakes
- Placing a small mark in a corner where one crop removes it.
- Covering the part of the screenshot the reader needs.
- Overwriting the only original with a watermarked copy.
- Treating a watermark as access control. Use a password for PDFs that must stay private.

Common questions
Can a watermark be removed?
Visible marks can often be cropped or retouched. Invisible marks are harder to remove but are not guaranteed to survive every edit.
Should every shared screenshot have a watermark?
No. Use one when the image could be mistaken for final or public material, or when credit matters.
