Free converters stamp a watermark on web assets by design. Four small ffmpeg wrappers do the job locally, and the watermark was the least of it: the real work was choosing the quality, preset and GIF palette flags ffmpeg lets you get wrong.
Photos into one PDF, a PDF under two megabytes, a layout inspected page by page — usually done by uploading to a stranger's website. Three small tools do it locally with Pillow and Ghostscript; the only real decisions were which defaults to bake in.
cp -r drops owner, permissions and timestamps, producing copies that look right and fail in use. A 58-line rsync wrapper makes the destination truly equal to the source — and most of its lines are refusals, because making it equal means agreeing to delete.
Retyping long Docker commands costs seconds, invites typos and taxes working memory. Ten short executables on PATH removed that cost; the interesting decisions were why not aliases, how to keep names guessable, and why one of them is 260 lines long.
