Static watermark

Statically defined image overlay

This function will watermark selected images with the same watermark - an image set in the Cloudimage admin console. This is useful for placing your company logo, name, or other copyright information. If you would like to watermark different images with different watermarks, please refer to the Dynamic watermark section.

Step 1. Upload your watermark

Log in to your Cloudimage admin console, navigate to Image Settings / Watermark, and upload your default watermark using the uploader.

Step 2. Start watermarking!

Available parameters


use watermark


(required) Activates the watermark function

watermark gravity

wat_gravity=X X=[north|south][east|west]|center| absolute|relative

Defines the position to "anchor" the watermark to

watermark scaling (relative to original watermark size)

wat_scale=X X=0..100

Watermark image scaling defined in in percent of the watermark dimensions

watermark scaling (relative to output image size)

wat_scale=Xp X=0..100p

Watermark image scaling defined in in percent of the output image dimensions

watermark padding

wat_pad=X[p][,Y[p]] X/Y=0..100[p]

Adds padding from the anchoring point in pixels (X) or in percent (Xp)

watermark positon


sets the position in percent from the resized image; works only with wat_gravity=absolute and wat_gravity=relative

watermark opacity

wat_opacity=X X=0..1

Defines watermark opacity

Use watermark

To activate the watermark function, you need to include the wat=1 parameter.

Watermark gravity

The wat_gravity parameter allows you to define the position of the watermark. You can choose between "fixed" anchor points (east, northeast, north, northwest, west, southwest, south, southeast, and center) or define the exact position (relative, absolute).

When using "compass" point gravity, the wat_pad parameter defines the offset from the chosen position. The padding can be defined in pixels (wat_pad=X[,Y]) or in percent of output size (wat_pad=Xp[,Yp]). The padding is applied after scaling the final image and then it is compressed (see Compression) and delivered via CDN.

To set the exact position of the watermark, you can choose absolute or relative gravity and use the wat_pos parameter to define the position of the top left or center point of the watermark, respectively. The position is always defined in percent of the resized image dimensions.

Watermark size

The watermark can be scaled relative to the original watermark image (wat_scale=X) or relative to the output image (wat_scale=Xp).

To keep the watermark-to-image proportions for all image resizes, you should use the wat_scale=Xp.

Please note that the watermark cannot be larger than the image - if larger, it is always scaled down first to match the image dimensions. Then, the wat_scale parameter values are applied.
