What Is an Add Watermark?

A watermark is a semi-transparent mark — a name, copyright line, or logo — drawn over an image so the source stays identifiable even after the file is copied. Photographers, illustrators, and stock sellers use them to discourage casual theft while keeping the picture viewable.

This tool draws the mark directly onto a canvas copy of your image, so the export is a single flattened file with no separate layer to peel off. Text mode lets you pick any caption and colour; logo mode accepts a PNG and preserves its transparency. A nine-point grid sets the anchor, and sliders control size as a percentage of image width plus opacity from 5 to 100 percent.

Corner placement is the least intrusive and most common, but it is also the easiest to crop out — centre or a larger mark resists removal better. All processing is local, so neither your photo nor your logo is uploaded anywhere.

Frequently Asked Questions

Can I use a logo image as the watermark?
Yes. Switch to logo mode and upload a PNG (transparency is kept). You can scale it and set its opacity over the base photo.
What opacity works best?
20 to 50 percent is the usual range — visible enough to deter reuse but light enough not to spoil the photo.
Where should I place the watermark?
Corners are common and unobtrusive; the centre is harder to crop out. Pick the position from the nine-point grid.
