Resize photos for emailing

[Android Central Question]

I have to send emails with photos as proof. I have a One Plus 3T Android phone. The photos I need to send are 4MB each, the email bounced back as too big.
There is no resize program in my phone.
What could you recommend?
Thanks a lot for your help

Photo and Picture Resizer.

Snapseed by Google will do the resizing when you use the "export" command.
