Runs several PDF tools in order on one document, so a routine becomes a recipe you can reuse. Write one step per line as "step | key=value | key=value" — rotate, crop, organize, flatten, repair, metadata, watermark, page-numbers, redact, fill-form, compress and protect are available, each using the very engine its own tool uses. Encryption has to come last, since later steps cannot read a protected file. The report shows what every step did and how the size changed.
