Batch Photo Renamer for macOS
Something not working, or a photo the app won't read the date from? Write to supportlap478@gmail.com and you'll get a real answer from the person who wrote the app.
It helps to know what camera or phone took the photo, what name you expected and what you got instead. If the app showed you a message, quoting it word for word is the fastest way to a fix.
Things people ask
Some photos show no date
The app uses the date the camera recorded inside the file — the EXIF metadata. Photos that were edited, exported by some apps, or downloaded from WhatsApp or a website often lose it. For those, add the file date piece instead: right-click the date piece and choose "Use the file date instead".
The time looks shifted by a few hours
It shouldn't. EXIF dates carry no time zone — they are the wall-clock time of the camera — so the app shows exactly the number stored in the file, without converting it. Videos are different: they do carry an offset, and the app shows the local time of whoever recorded them. If you see something that doesn't match, please write in.
It says there are conflicts and won't rename
Two or more photos would end up with the same name, which would mean one overwriting another. The app refuses to do that. Add a number piece to your rule and the conflicts disappear — for example date plus number gives 2026-07-14-001, 2026-07-14-002.
Can I undo?
Yes. The Undo button puts every file back to its previous name. The undo record is written before the renaming starts, so it survives even if something goes wrong halfway.
Does it rename my photos in the Photos app?
No. It works on files in folders you choose yourself. Photos stored inside the Photos library are managed by macOS and cannot be renamed by any app.
What about RAW and video?
RAW files from Canon, Nikon, Sony, Fujifilm, Olympus, Panasonic, Pentax and Sigma are supported, along with JPG, HEIC, PNG and TIFF. MOV and MP4 videos use their own recording date, so photos and clips from the same trip line up together.
Does anything leave my Mac?
No. There is no network code in the app at all. Your photos are never uploaded, and nothing about your usage is collected or transmitted.
