Automator and Preview are a match made in heaven.
When I got my mortgage I needed to get approval and collate all our documents in one night, I just told Automator to grab all the pdfs in a folder and merge them, it took like 2 minutes to get all our signed paperwork done (after the reading and signing). Plus then I knew I didn’t forget anything we needed, everything on the folder was combined.
I’ve used it for a ton of other things over the years, like bulk photo editing for websites to taking a photo every 5 seconds for a timelapse.
I still find it less complicated to bulk rename files than using Python or bash.
Oh great, you broke the only rule in this community.
