EXIF Date Fields Explained
| Field | Description | Used By |
|---|---|---|
| DateTimeOriginal | When the photo was originally taken | Google Photos, Apple Photos, most photo apps |
| DateTimeDigitized | When the image was digitized (usually same as original) | Some photo management software |
| DateTime | When the file was last modified | Windows Explorer, file managers |
Common Use Cases
- • Fixing photo dates after a camera clock reset or battery change
- • Correcting timezone offsets from travel photos
- • Merging photos from multiple cameras into chronological order
- • Restoring lost EXIF dates on scanned or edited photos
- • Adjusting dates before uploading to Google Photos or iCloud
Understanding Photo Timestamps
Every JPEG photo carries a small block of metadata called EXIF (Exchangeable Image File Format). When you press the shutter, your camera or phone stamps the current date and time into this block. That timestamp is what photo apps read to sort your library, group pictures into "moments," and show a capture date under each image. If the camera's internal clock was wrong (a common problem after a dead battery, a firmware reset, or crossing into a new timezone), every photo from that session inherits the error, and no amount of re-sorting in the app will fix it. Editing the EXIF date at the source is the reliable way to put your memories back in the right order.
This tool distinguishes between two ways of correcting dates. Set Date mode lets you type an exact date and time, which is ideal when you know precisely when a photo should be dated or want to give a whole batch the same timestamp. Time Offset mode shifts every photo by a fixed amount (a number of days, hours, minutes, and seconds you add or subtract), which is exactly what you need when the camera clock was consistently off by, say, three hours because it was never changed for daylight saving time or a trip abroad. Offset mode preserves the relative spacing between shots, so a burst taken seconds apart stays seconds apart after the correction.
Processing happens entirely in your browser using the piexifjs library. Your JPEGs are read into memory, the EXIF date fields are rewritten, and the result is offered back to you as a download: a single file, or a ZIP when you edit several at once. Because none of this touches a server, your photos never leave your device, which matters when you're organizing personal or family pictures. The tool accepts up to 50 JPEG photos per session, with a limit of 30 MB per photo, and works only on JPEG/JPG files because that is the format EXIF metadata is designed for.
Frequently Asked Questions
What is EXIF date and why would I need to change it?
EXIF is the metadata your camera embeds in each JPEG, including the date and time the photo was taken. You might change it to correct a wrong camera clock, adjust for a timezone, or restore a capture date that was lost when a photo was scanned, exported, or transferred between devices.
What's the difference between DateTimeOriginal, DateTimeDigitized, and DateTime?
DateTimeOriginal is when the photo was captured and is the field most photo apps like Google Photos and Apple Photos use for sorting. DateTimeDigitized is when the image was digitized, usually the same value. DateTime is the last-modified timestamp used by file managers like Windows Explorer. This tool lets you edit any combination of the three.
When should I use Time Offset instead of Set Date?
Use Time Offset when your camera clock was consistently wrong by a fixed amount, for example three hours off after crossing timezones or missing a daylight-saving change. It shifts every photo by the same interval while preserving the spacing between shots. Use Set Date when you want to assign an exact date, or give a whole batch the same timestamp.
Are my photos uploaded to a server?
No. All EXIF editing runs locally in your browser using the piexifjs library, so your photos never leave your device. This is why the tool works even offline once the page has loaded.
Why only JPEG files? Can I edit PNG or HEIC dates?
EXIF date metadata is designed for the JPEG/JPG format, which is what this tool reads and writes. PNG files do not store standard EXIF capture dates, and HEIC uses a different container. Convert those to JPEG first if you need to set an EXIF date.
How many photos can I process at once?
You can load up to 50 JPEG photos per session, with a maximum of 30 MB per photo. Editing a single photo downloads one file; editing several downloads them together as a ZIP archive.
