I submitted a PDF to a client. The PDF was 7MB in size.
Client: Great work, can we reduce the files size though?
I reduce the PDF’s size and send again.
Client: It’s too small now. The submission guidelines state the file needs to be 5MB.
Me: Are you sure, the guidelines don’t say the file only needs to be less than 5MB?
Client: Look I don’t want to risk uploading a file that’s incorrect. Just make it 5MB exactly!
I put some invisible garbage into the file until it’s the correct size and send again.
The sad part is this was the first of twenty submissions, all of which have to be exactly 5MB, apparently.
