  title: Adobe PDF Services Compress PDF
  summary: Upload a PDF, compress it at a chosen level, poll the job, and get the compressed download URI.
  description: >-
    Reduces the file size of a PDF using the Adobe PDF Services asynchronous job
    model. The workflow registers the source PDF by requesting an upload asset,
    submits a compress operation at the chosen compression level, polls the
    operation status until it is done or failed, and resolves a temporary
    download URI for the compressed output. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
