Processing and current limits

This supported operation runs in your browser after you select an input. Free use allows 25 MB files and shares 20 completed operations per day across tools. Pro removes those product limits, but browser memory and device performance can still limit large files.

Review security and data handling and current limits before processing a sensitive or important original.

Formats and limitations

Treats values over ten digits as milliseconds and shorter values as seconds.

Invalid or out of range values may fail. The digit rule can misclassify unusual historic or far future timestamps.

Common uses

  • Read a log timestamp.
  • Inspect a token time claim.
  • Compare UTC and local dates.
