Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. PDF-BatchScale for Mac lies within Productivity Tools, more precisely Office Tools. The actual developer of this free software for Mac is Leigh Verlag.
From the developer:
PDF-BatchScale quickly scales many PDF files to any size PDF. The aspect ratio of the original PDF doesn’t change, so if the output page size is different than the original PDF, Batch Scale PDF will automatically add margins to the output PDF as needed.
You may want to check out more Mac applications, such as PitStop Extreme, FileOpenInstaller or Portable AbiWord, which might be similar to PDF-BatchScale.
