The right choice depends on your needs

Zamzar and Transloadit were built to solve real production problems. Both are used in serious systems, and both have strengths.

Choose based on your workload: file types, delivery targets, and how much control you need over upload and processing. If you need broad file processing with a self-hostable upload stack and an API that has been stable for 17 years, Transloadit is worth a trial. If your needs are narrower, Zamzar may be the better fit.

Best for

  • ✓Teams needing straightforward file format conversion across 1100+ format pairs via a simple REST API.
  • ✓Projects requiring document, e-book, and CAD conversions alongside standard media formats.

Not ideal for

  • •Workflows requiring multi-step media pipelines, adaptive streaming, or AI-powered processing.
  • •Applications needing real-time webhook notifications instead of polling-based status checks.
