1. Put it into paint. 2. Press Ctrl+t 3. Drag the edges out to make it bigger 4. Save the picture. 5. Upload it into your sig pic. NOTE: The pixels will be slightly distorted, being that this is a smaller picture to begin with.
Thanks for the help but i dont have paint i think i deleted \ edit: I got paint back but my signature is still small look below
I suggest making a new one, if you try to make it bigger it will just pixelate and look bad. A normal signature is 300x150 if you're wondering too.
