Hello everyone

I am insure if this is the right sub to post this question or maybe this question is too far beneath the expertise of average user of this sub but her it goes.

First off, I am not a photographer. i use my phone to take photos of the moments i wanna capture.

now, my phone is FULL of pictures of my little son (same as any parent i guess) so i was thinking of making an album of some of our memories. Now the problem is when i am uploading the pictures to the website so i can collect the printed photos, The size means some of the photo has to be cropped. Is there any way a picture which doesn’t have the aspect ratio (i dont know what i am talking about).

Any help will be appreciated or even if the question is too vague or inaccurate, apologies in advance.
