Easily convert from TIFF to PNG?

[anderssok09]

I have thousands of photos, but they were all scanned in 1200dpi TIFF files. Is there anyway I can start easily converting those images to PNG files without losing the dimensions or quality of the photos? Thanks in advance!

My solution would be:
Image > Automate > Image Processor Pro..

if you don't have it go here - http://blogs.adobe.com/jkost/2015/06/image-processor-pro-for-photoshop-cc-2015.html

here is the UI, If you need help with it just ask
