The right choice depends on your needs

Both Fastly Image Optimizer and Transloadit handle real production workloads, with different 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, Fastly Image Optimizer may be the better fit.

Best for

  • Teams already using Fastly CDN who want zero-latency image optimization at the edge.
  • Websites needing automatic format negotiation (WebP/AVIF) without separate processing infrastructure.

Not ideal for

  • Projects requiring video encoding, audio processing, or document conversion beyond images.
  • Teams needing standalone file processing without a CDN dependency.
