PDF invocing with a ton of photos

For invoice reimbursements, use imagemagick CLI tools to help us make invoice PDF compliance easy!

# Use whatever package manager you need, likely:
sudo apt install imagemagick

Compress Images

Most phones are way to big Mpeg wise... we want to send pics low quality but legible:

# Irreversably overwite in place (suggested)
for i in *.jpg; do convert $i -quality 20% $i; done;

# OR make new files in place(meh)
for i in *.jpg; do convert $i -quality 20% smol-$i; done;

PDF Generation

Assuming:

• You have a folder that includes only the photos you want in a single PDF
• Photos are in an order that numerically makes sense (if you need it in accounting to match). Most pics now have a timestamp as a file name that makes this linear in time of capture by default.
