Support

Every processed photo is saved into your photo library as a new copy. The app also shows the exact count of saved copies on the result screen, and the Open Photos app button takes you straight to your library.

Your original photos are never modified, renamed or deleted.

The app writes the EXIF DateTimeOriginal field, which is the capture timestamp your photo library uses for sorting. iOS does not expose any API that lets a third-party app rewrite a photo asset's file-system creation date, so that value cannot be changed by any app on the App Store.

A photo is skipped rather than guessed at. The most common reasons are:

• No date in the filename — for Extract Date From Filename, the app only proceeds when it finds a real date. It never invents one.
• No existing capture time — shifting time requires a starting point, so a photo with no EXIF capture timestamp cannot be shifted.
• Unsupported format — PNG, GIF, ProRAW and DNG are not supported.
• The photo is only stored in iCloud — download it to the device first, then run the task again.

Each skipped photo is listed on the result screen with its own reason, so you always know exactly what happened.

A failure means the app could not produce a verified copy. After writing a new timestamp, the app reads the value back. If it does not match exactly, the output file is discarded and reported as failed — this guarantees you never end up with a duplicate that silently carries the wrong time.

Most failures come from a photo that cannot be decoded, or from temporary storage being full. Free up some space and try again, and email us the file name if the problem repeats.

Photos that exist only in iCloud are marked with a cloud icon and cannot be selected, because processing must happen entirely on your device. Open the photo in the Photos app so iOS downloads it, then return to Photo Date Fix and select it.

For a Live Photo, only the still image's metadata is updated. The paired video is not included in the processed copy. Live Photos are only partially supported.

YYYY-MM-DD, YYYYMMDD, YYYY_MM_DD, YYYY.MM.DD and YYYYMMDD-HHMMSS.

When a filename contains only a date and no time, the app fills in the fallback time. You can change that fallback in Advanced Options on the home screen; the default is 12:00:00.

Yes. The shift is applied to the timestamp value itself, so adding three hours always adds three hours, regardless of daylight saving changes. The app adjusts the absolute time value you specify and never applies a time zone of its own.

No. The EXIF capture timestamp format has no time-zone field at all. The app writes the exact absolute time you configure, in the format yyyy:MM:dd HH:mm:ss.

There is no fixed limit. Photos are processed in small chunks so the interface stays responsive, and you can cancel at any point. For large batches, keep the app open while processing runs and give it a moment on slower devices.

Copies that were already saved stay in your library, and photos that had not been processed yet are left completely untouched. Nothing is ever left half-written, because every copy is verified before it is saved.

Two global defaults: the fallback time used when a filename contains only a date, and the output quality of saved copies. They are stored locally on your device and reused by every task.

Yes — it works exactly the same, because the app makes no network requests at all. It has no network permission, no analytics, no tracking and no advertising. Your photos are processed entirely on your device and never leave it.
