Rename photos by the date they were taken

Reads the real date taken

Uses EXIF "date taken" metadata, not the file's upload or copy date — so renamed photos stay in the order you actually shot them.

Numbered in shooting order

Photos are numbered by when they were taken, even if they were dropped in a different order or came from multiple cameras.

Nothing leaves your browser

Your photos and their metadata are read locally. No uploads, no account, and no server ever sees your files.
