SignMyImage is an intuitive software utility that allows you to apply digital signatures to your images for copyright purposes. It offers support for BMP, PNG, JPG and TIF file types, and includes several options.

Installing SignMyImage is a fast and easy job that shouldn't present any issues, thanks to the fact that it bundles familiar options. Once finished, you are welcomed by a large window with a clear-cut structure, where you can open an image file to get started.

It is possible to zoom in and out of the picture, fit it to the screen, reload it from the source, detect any existing signatures, as well as to sign it with letters, capitals, dashes, and numbers in a highlighted area. A confirmation message is shown at the end.

The software tool supports multiple UI languages, and it can detect signatures and apply them to images in batch mode recursively. You can also pick the number of CPU cores to use, to either favor app performance or minimal resources usage.

We haven't encountered any unpleasant surprises in our tests as far as stability goes, thanks to the fact that SignMyImage did not hang, crash or pop up error messages. It runs on low CPU and RAM, so it shouldn't affect system performance either.

Although it is not the most feature-rich application we've seen, SignMyImage delivers a fast and effective solution to applying digital signatures to images of popular file types. Plus, no special experience is needed in order to work with this program.
