Watermark an image
Mark your photos as yours with a line of text or a logo. Put it quietly in a corner, or repeat it across the whole picture so it cannot simply be cropped off.

About this tool
A watermark does two different jobs, and they pull in opposite directions. As a credit, it should be small and out of the way: your name in a corner at half strength. As a deterrent, on proofs or previews that someone might use without paying, it should cover the picture so that removing it is more trouble than it is worth. The "Where" setting switches between the two.
It is worth being clear about the limits. A watermark makes a picture awkward to reuse and makes its origin plain; it does not stop anyone copying the file, and a mark in one corner can be cropped away. The repeated layout is the harder one to remove, at the cost of getting in the way of the picture.
What you get
- Text or logo watermark
- One position, or repeated on a slant across the picture
- Opacity from 5% to solid
- Size and margin that follow each picture
- Up to 20 images at once
When to use the image watermark tool
Client proofs
Photographers send repeated-mark previews so that a client can choose pictures without having usable copies before paying.
Artwork and illustration shared online
A name in the corner keeps the credit attached when a picture is reposted without its caption.
Stock and catalogue previews
A faint mark across a product or stock image shows what is on offer while making the preview unfit for use.
Documents sent as images
A "draft" or "copy" mark across a scanned page makes its status obvious at a glance.
Choosing layout and opacity
| Purpose | Where | Opacity | Effort to remove |
|---|---|---|---|
| Credit or signature | One place, a corner | 40 to 60% | Low: it can be cropped off |
| Brand mark on a post | One place, bottom centre | 60 to 100% | Low to moderate |
| Proof or preview | Repeated all over | 15 to 30% | High: it crosses every area |
| Draft or confidential stamp | One place, centre, large | 20 to 40% | Moderate |
How it works
For the repeated layout the mark is drawn again and again on a grid turned 30 degrees, so the lines of marks rise from left to right. Alternate rows are shifted by half a step, and the grid is made large enough to cover the corners of the picture after turning. The spacing follows the size of the mark itself: about one and a half mark-widths plus its height from one copy to the next, and three mark-heights between rows.
All copies are drawn on one transparent layer, which is then laid over the picture at the chosen opacity, so that overlapping edges do not add up to darker patches. A text mark uses the same sizing as the text tool, a share of the picture's shorter side; a logo mark is between 4% and 60% of the picture's width. The picture is encoded as a new file, and the original's metadata is not carried over, so if you rely on copyright fields in the EXIF data they will need adding again.
Common problems and how to fix them
- The watermark is invisible on parts of the picture
- White text disappears on pale areas and dark text on shadows. Switch on the outline, which edges the text in the opposite tone, or raise the opacity.
- The repeated mark is too dense or too sparse
- The spacing follows the size of the mark. Make it smaller for more, closer copies, or larger for fewer.
- The mark covers the subject
- Use "One place" and pick a corner away from it, or lower the opacity of the repeated mark until the picture reads clearly through it.
- I chose Logo and nothing appears
- Press "Choose logo" and select a file. Until then the picture is shown without a mark.
Frequently asked questions
Will a watermark stop people stealing my photos?
It discourages it and it makes the source obvious, but it cannot prevent copying. A mark in one corner can be cropped out. A repeated mark across the picture is much harder to remove cleanly. For real protection, share only reduced-size copies and keep the full-size originals to yourself.
What opacity should I use?
For a credit in a corner, 40 to 60% is visible without shouting. For a repeated deterrent mark, 15 to 30% is usually enough to spoil reuse while leaving the picture easy to judge. Light text on a pale photo may need the outline switched on to show at all.
Can I remove a watermark with this tool?
No. This page only adds marks. Nothing on this site removes watermarks from pictures.
How do I type the © symbol?
It is already in the sample text, so you can simply edit the name after it. On Windows it is Alt + 0169 on the number pad, on a Mac it is Option + G, and on a phone it is under the long-press of C or in the symbols keyboard.
Text or logo: which makes the better watermark?
Text is quicker and always legible: a name or a web address tells people where the picture came from. A logo is more recognisable for an established brand but says nothing to someone who does not know it. Many people use a logo with the name as part of it.
Does the watermark reduce image quality?
Only where it is drawn. The rest of the picture goes through one more save, at the quality you set; at 90% that is not visible. Choose PNG as the output if you want no further loss at all.
