I use ASHAMPOO SNAP 11. I have quite a lot of Ashampoo software and again, quite often you can get some of the paid programs free. I've been using SNAP since version 5, and it does everything I need it to do.
There is a FREE version of SNAP here ... https://sharewareons...p-6-19-99-value ... Again on Shareware on Sale's site. I haven't checked it, but again what have you to lose. Have a good look through all the free offerings on Shareware on Sale, you may find quite a lot of good FREE software.
Just to be clear, with Screenshot software you are doing just that, taking a shot of the screen PIXEL BY PIXEL ... at the resolution of the screen. Enlarging it will ALWAYS lose quality.
If any of you are imterested in Photography, I would certainly suggest you grab LUMINAR 4 while it is still available ... https://sharewareons...-4-100-discount.
