Is my logo file uploaded?

No. It is read from your device and decoded in the browser like any other image, then drawn onto each output. It never leaves the machine.

Can I use my brand's font?

Not currently. Processing runs in a worker thread, which does not have access to page-loaded webfonts, so text watermarks use the generic system families. A logo file is the way to keep exact brand typography.

Can I tile the watermark across the image?

No — the watermark is placed once, at one of nine positions. Tiling is not implemented, so it is not offered.

Watermark a whole batch

Stamp text or your own logo onto every image, sized as a share of image width so mixed dimensions stay consistent.

Relative sizing is the point

A watermark specified in pixels looks correct on one image and wrong on the next. Twenty-four point text is prominent on an 800-pixel proof and nearly invisible on a 6000-pixel master. Both the text size and the logo scale here are percentages of each image's width, so a batch of mixed dimensions comes out looking deliberate.

The margin works the same way, which keeps the stamp the same visual distance from the edge regardless of resolution.

Text or logo

Text watermarks are quick and legible: a studio name, a domain, a copyright line. Because processing runs inside a worker thread, only the generic system families are available — sans, serif and mono — so a text watermark cannot use a custom brand font.

For brand marks, use a logo file instead. Choose a PNG or WebP with transparency from your device; it is read locally like any other image and never uploaded. Set the opacity somewhere between 60 and 85 percent for a mark that reads clearly without dominating the photograph.

What a watermark does and does not do

A visible watermark deters casual reuse and identifies the source when an image travels. It is not copy protection: it can be cropped, cloned out, or simply ignored. Place it where removal would damage the image if that matters to you, and keep unwatermarked masters.
