Unix Timestamp Batch Converter
Paste a batch of Unix timestamps and convert them to readable dates at once. Seconds and milliseconds are detected automatically. A small reverse converter below turns a date and time back into a timestamp.
Separate values with commas, spaces or new lines. 10 digits are read as seconds, 13 digits as milliseconds.

How to use
- Paste your timestamps into the box, up to 500 values.
- Click Convert to see each value as UTC time, your local time and relative time.
- Use Copy as CSV to take the full table into a spreadsheet.
Note: Values outside the range 1970 to year 3000 are reported as invalid. Local time uses your device time zone. Nothing is uploaded; all conversion happens in your browser.
