There are many solutions available, I went with Easeus Partition Master Pro (it has to be a paid Pro version if you are converting a system drive - for a regular data partition you can use Easeus Partition Master Free).
You can also use windows disk management tool, but it only works on empty partitions, not quite useful unless while partitioning the drive for the first time.
There are probably other solutions as well, but i always liked Easeus products, never even needed anything else for this purpose.

The MBR2GPT Disk Conversion Tool in Windows 10 v1703
Windows 10 Creators Update v1703 introduces a new MBR2GPT Disk Conversion Tool using which you can safely and non-destructively convert a Windows 10 computer from legacy BIOS to UEFI disk partitioning, as well as automate the conversion as part of your in-place upgrade process from Windows 7 to Windows 10. Moreover, unlike Wipe & Load methods, all of this can be achieved without having to move your data off the disk. https://www.thewindowsclub.com/mbr2gpt-tool-windows-10
