What you get on the free tier

  • -> A free API key (pdk_) and a starting token balance, no card needed.
  • -> Byte-exact lossless compress / decompress with a +1 byte never-worse floor on Pedulli's own output and a SHA-256 roundtrip check.
  • -> Best-of-N racer that includes xz, zstd and brotli - it wins on specific structured data classes and openly concedes losses (xz on long English text, brotli on small generic text).
  • -> Files under 1 MiB run on our EU servers, deleted after the job.

Need more throughput? Upgrade to Pro for the REST API, webhooks and 10 GB/month included.
