Unix time, also called epoch time, counts the seconds that have passed since 1 January 1970 at 00:00:00 UTC. Programming languages, databases and log files use it to store a date as a single number. This converter reads seconds or milliseconds and shows the date in UTC and in your time zone.
Today a timestamp in seconds has 10 digits (for example 1700000000) and one in milliseconds has 13. The converter detects it automatically.
No. The conversion happens in your browser: nothing is uploaded.
You usually don't need to change anything: Private Photo Converter already picks the best settings.
Choose the language of the app. “Automatic” uses your device language.
Choose the light or dark theme. “Automatic” follows your device.
Choose the colors of the app. They adapt to light and dark mode.
The higher it is, the better the photo looks, but the heavier the file.
For lighter photos to send, choose “Small”.
Private Photo Converter lowers the quality and, if needed, the size until each photo fits. Works with JPG, WebP and AVIF.
