PDF Converter

Let people turn the files they upload into PDFs, and PDFs back into editable formats.

What it does

A conversion service that accepts an uploaded document and returns it in a requested format, with progress and a downloadable result.

How it works

  1. 1 Start from the app's existing upload path rather than adding a second one. If File Upload, Upload Malware Scanning, or Secure File Downloads already exist, the converter consumes what upload produces and hands its output to the existing download route, so permissions and scanning are inherited rather than reimplemented.
  2. 2 Decide the conversion pairs you will actually support and list them in the interface. A short honest list of office documents, images, and PDF to text beats a control that offers every combination and fails on most of them.
  3. 3 Enforce file size, page count, and accepted types on the server before any conversion starts. A limit checked after the file has been parsed has already cost you the memory and the CPU you were trying to protect.
