Batch & Automate

Turn repetitive PDF work into one pipeline: merge, OCR, compress, watermark, number, and encrypt in a single workflow you can save and reuse.

Best for: Finance, operations, IT, teams

The usual order: merge the sources, OCR the scans, compress the result, then number, watermark, and protect the packet — or chain all of it in one pipeline run.

  2. 2Reorder steps and configure each one
