I need to upload my signature in a PDF document, but I do not know how to edit the background of this image.
I wish to remove the bluish-tint background, and make it pure white.
Can anyone help me with this, please?

Another method is to use
The easiest and fastest method for a non-designer with access to Photoshop would be like this:
With a little more effort, you could make a much better finish.
There are many other methods to achieve this, as it's a very simple task with the right tools.
There are lots of methods to achieve what you want in Photoshop.
You can use a non-destructive method such as a layered Gradient Map.
Take note that the signature isn't cut out from its background. If you want a transparent background, simply flatten all layers and use the Magic Wand. The selection will be more accurate with lesser tolerance adjustments since the image now has a higher contrast.
Let me outline another approach I find useful especially in the context of a signature for letters or PDF documents.
We can quite easily create a vector graphic from a scanned original signature. This can be done with a variety of applications. Here is how I made it using Inkscape.
We can then further refine the resulting colours, or apply variable transparency levels to the objects created if we need better results.
A vectorized signature has the advantage that it can be smoothly resized to any size, can be differently coloured with no effort, and it can be embedded in a variety of documents as a rather slim vector graphics.
This is very easy in Gimp. Just use the bucket tool to fill the background white, and export. Or if you want to go one stage further, then after that, use the select with the same colour tool, press delete (Making sure that your image has an alpha channel) add a new white layer, merge down and export as a jpg, png or whatever.
