How do you date stamp photos on iPhone, including photos you already took?
Short answer: the iPhone camera cannot stamp a photo, before or after the shot, so the date has to come from somewhere else. For photos already in the Photos app you have two real choices. Write the date on the picture with Markup, which is quick and worth exactly as much as your word. Or use an app that opens the photo file, reads the date, time and GPS position the camera wrote into it, and prints those values on a copy.
The second way is the useful one, with one condition: the stamp must say the values came from the file, not from the clock at capture. A date in a file can be missing (WhatsApp photos, screenshots) or changed (Photos lets you edit it in a few taps). A stamp that hides that is worse than none.
Does the iPhone Camera have a date stamp setting?
Apple's user guide lists what you can change under Settings > Camera: the grid, Preserve Settings, Live Photos, formats and a few more. No watermark or date stamp option is on that page, and Apple's 2024 help article on taking and editing photos does not mention one either. Some Android cameras have such a setting; the iPhone does not. Everything below is about photos that already exist.
How do you date stamp a photo at the moment you take it on iPhone?
Only with a camera app made for it. The built-in Camera saves the date and location in the file's metadata, where nobody sees them, and offers no way to print them on the picture. A timestamp camera app draws the date, time and, if you want, the address onto the image as the photo is taken, and the better ones also note where each value came from (phone clock, GPS, typed). That is the only route that can say "this is what the phone reported when the shutter fired"; every option below works on photos that already exist and can only say what the file or the person typing said. The overview of every way to date stamp photos compares them.
Option 1: type the date with Markup
Open the photo in Photos, tap Edit, tap the Markup button, tap Add, choose the text tool and type something like "Nov 6, 2026, 2:40 PM". Tap Done twice. Thirty seconds.
The problem is what the text means. You typed it. It has no connection to when the shutter fired, and the reader knows that. To a client, an adjuster or a landlord, a typed date is a statement you are making. Markup edits can be reverted in Photos, but to keep the untouched file next to the marked one, duplicate the photo first.
Option 2: fix the date Photos shows (this is not a stamp)
Since iOS 15 you can change a photo's date, time and location inside Photos: open the photo, tap the More button, tap Adjust Info, then Adjust Date & Time or Adjust Location. Select lets you do a batch; Revert undoes it.
People find this while searching for "add timestamp" and think it does the job. It puts nothing on the image; it changes what Photos records about it. Handy when a camera clock was wrong, and also why a date in the info panel is only a claim: anyone can set it to anything. Apple says sharing a photo "includes sharing its associated metadata, such as date and time, location," so the edited value travels with the file.
Option 3: an app that reads the date from the file
Every iPhone photo carries EXIF metadata: the date and time the shutter fired (DateTimeOriginal), the time zone offset (OffsetTimeOriginal) and, if the Camera had access to Location Services, a GPS block with coordinates. An app can read those fields and print them in a band on a copy of the image. Three things about how this works on iOS:
- The app does not need access to your whole library. Since iOS 14, Apple's photo picker runs in a separate process, shows the full library (even under "limited" access) and hands the app only what you select, with no permission prompt. An Apple engineer wrote on the developer forums that an app can load the original file this way and get "most metadata" without library permission; a developer write-up shows the DateTimeOriginal and GPS blocks arriving intact.
- Location is in the file unless it was removed. GPS fields go missing when the photo was shared with Location switched off in the share sheet options, set to "No Location" under Adjust Location, or taken with Location Services off for the Camera. A date with no coordinates usually means one of those.
- The stamp should name its source. "Time: from photo file" is a different claim from "Time: phone clock, checked against a time server at capture". Both are honest; a stamp that blurs them is not. An app like Asof prints the source next to each value and says so when the file has no date.
Which photos still have a date to read?
Your own photos almost always do. Photos from someone else depend on the road they took:
- AirDrop and sharing from Photos keep the metadata. Apple documents that sharing includes date, time and location, and that "All Photos Data" (AirDrop only) sends the original file with its edit history.
- iMessage is not described separately by Apple. Older user tests, collected in our guide on whether a photo keeps its timestamp when you text it, found iPhone-to-iPhone photos keep their metadata unless the sender switched Location off. Observed, not documented.
- WhatsApp in normal photo mode compresses the image and strips most of the EXIF; sent as a Document, the original arrives intact. WhatsApp does not publish this; it comes from third-party tests.
Two format details can surprise you. A Live Photo sent to a device or service that does not support Live Photos goes as a still only. And when the iPhone captures in HEIF (Apple's recommended setting): shared to something that cannot read it, the file "might automatically be shared in a more compatible format, such as JPEG". That is no longer the file the camera wrote, so keep the HEIC original and stamp from that.
What a later stamp can and cannot say
| Stamp added… | Where the date comes from | What it can honestly claim |
|---|---|---|
| At capture, by a timestamp camera | Phone clock at the moment of the shot, ideally compared with a time server; GPS fix at that moment | This is when and where the photo was taken, with the clock check and GPS accuracy shown |
| Later, from the file | EXIF fields written by whatever camera took it, possibly edited since in Photos | This is what the file said when it was stamped |
| Later, typed in Markup | You | Nothing beyond "the person who sent this says so" |
None of these detects a fake; pixels and EXIF can both be edited. A visible stamp lets the reader see the date without opening an info panel and tells them how much weight to give it.
Step by step: stamp old photos without hiding where the date came from
- Check the photo still has its date. Open it in Photos and swipe up. Capture date plus device and lens details means the EXIF is there. The day you received the file and no camera info means it is gone.
- Keep the original. Stamp a copy; leave the HEIC file untouched.
- Pick the photos in an app that reads EXIF and prints date, time and, if present, coordinates on a band below the image, marked as read from the file.
- Add what the file cannot know. Street address, job name, a note on what the photo shows, each marked as typed.
- Put the series into one PDF with each photo's date, location and source underneath, so the reader gets one file instead of a dozen loose images.
- Send the originals as well. Share from Photos with the format set to Current, or AirDrop with All Photos Data on. The stamped copy is for reading; the original is what the other side can check. And never backdate.
Questions people ask
How do I date stamp photos on my iPhone?
Not with the built-in Camera: Apple's Camera settings cover the grid, Preserve Settings, formats, Live Photos and similar options, and none prints a date on the picture. For new photos you need a camera app that stamps at capture; for photos already taken, type the date with Markup or use an app that reads the date from the file. The date itself lives in the file's metadata, which Photos shows in the info panel.
If I change the date in Photos with Adjust Date & Time, does that add a stamp?
No. It changes the date Photos records for the photo, with a Revert option, and nothing appears on the image. Because anyone can change this value in a few taps, a date in the info panel is a claim about the photo, not a stamp on it.
Can an app read the original date from an iPhone photo without full access to my library?
Yes. Since iOS 14 the system photo picker runs outside the app and hands over only the photos you select, without a permission prompt. An Apple engineer has said an app can load the original file this way and read most of its metadata; developers show the capture date and GPS block arriving with it.
Why does a photo someone sent me show no date or location when I stamp it?
The metadata did not survive the trip. WhatsApp in normal photo mode removes most of it; AirDrop and sharing from Photos keep it unless Location was switched off; a screenshot carries no capture date from a camera, only the time the file was made. An honest stamp says the date is missing instead of printing today's date. The same question on Android is covered in how to add a timestamp to photos you already took (Android).
