Does a phone photo keep its timestamp when you text it?
Short answer: sometimes, and you usually can't tell which. The date and time a photo was taken are stored in hidden metadata (EXIF) inside the file, not in the picture. Some ways of sending keep that metadata; many compress the photo or strip it; and the person on the other end never sees it unless they go looking. Even when it survives, anyone can change it in a few taps.
If the date matters — a damage claim, a deposit, a job you need to get paid for — put the date where people can see it, keep the original file, and send it in a way that doesn't touch it.
Where the date in a photo actually lives
Every phone photo carries a block of EXIF metadata. Three fields matter here:
- DateTimeOriginal — when the shutter fired.
- OffsetTimeOriginal — the time zone offset (added to the EXIF standard in 2016, so older files may not have it).
- GPS fields — latitude, longitude and more, stored separately. They exist only if location was on for the camera.
The "created" and "modified" dates you see in a file browser are something else: they belong to the file system, not the photo, and they reset to the current time whenever the file is copied or saved. That's why a photo you received yesterday can show yesterday's date in Files even if it was taken last year.
What happens on each channel
Here is the uncomfortable part: Apple, Google, Meta and the carriers mostly don't publish what their apps do to metadata. The table separates what is documented from what is only reported, as of October 2026. Apps change this without notice.
| How you send it | Date & GPS on the received file | How solid is that |
|---|---|---|
| WhatsApp, normal photo | Stripped, and the image is compressed | Reported by Amnesty's Citizen Evidence Lab |
| WhatsApp, sent as Document | Original file, metadata kept | Reported by Amnesty's Citizen Evidence Lab |
| WhatsApp, HD photo | Re-encoded; metadata handling not documented | Unclear |
| SMS / MMS | Carriers cap image size (e.g. about 1 MB on T-Mobile, 1.2 MB on Verizon), so photos are recompressed; metadata is commonly stripped | Size limits documented; stripping reported, not documented |
| RCS (Google Messages) | Heavy recompression; metadata unknown | Compression reported; metadata unclear |
| iMessage (iPhone to iPhone) | Has been reported to keep metadata including location, unless Location is turned off in the share options | Reported (older tests); not documented by Apple |
| AirDrop | Keeps metadata; "All Photos Data" option sends edit history too | Reported |
| Google Photos link or shared album | Location not included by default | Documented by Google |
| Slack | Location stripped on upload; some other EXIF kept; date not tested | Reported (2020 test) |
| Signal, Messenger | Commonly said to strip metadata | Unclear |
| Email attachment | Usually the original file — unless your mail app offers to resize it, which re-encodes the image | Unclear |
| Screenshot of the photo | A new image with its own date; the original date is gone | Follows from how screenshots work |
Two settings change the picture. On iPhone, the share sheet has Options → Location; switch it off and the photo goes out with "Location Not Included." On Samsung phones, the Gallery share sheet has a "Remove location data" checkbox. On Android 10 and later, apps that don't hold a special permission get photos with GPS already removed, so a sending app may never see the location at all.
Photos inside a PDF or Word document
When you paste photos into a report, whether the EXIF inside each image survives depends on the program that builds the file. Some tools pass the image through untouched; others re-encode it and drop the metadata. Either way, no PDF viewer shows it. The person reading your report sees a picture and nothing else — whatever date you want them to know has to be written on the page.
Even when the date survives, it proves little
EXIF is easy to edit. On an iPhone (iOS 15 and later), open a photo, tap the i, then Adjust, and change the date, time and location. Several photos can be changed at once from the share menu. Google Photos lets you edit the date and time from the details panel. On a computer, a free tool like ExifTool rewrites all the date fields in one command, and the result looks normal to anyone not doing forensic analysis.
That's why the other side in a dispute will often say a photo "could have been taken any old time." The date in the file is a claim, not a fact.
A visible stamp: what it fixes and what it doesn't
A date, time and address drawn into the pixels survives everything that strips metadata: texting, screenshots, pasting into a PDF, printing. The reader sees it without opening an info panel. That solves the "nobody sees it" and "the app removed it" problems.
It doesn't solve editing. A stamp is pixels, and pixels can be faked. What makes a stamp useful is how much it tells you about where its own data came from:
- Was the time read from the phone's clock, or checked against network time? A phone clock can be set to anything.
- How accurate was the GPS fix — 5 meters or 500?
- Was the address looked up automatically or typed in by hand?
- Was the stamp added when the photo was taken, or later?
A record that answers those questions honestly is far harder to argue with than one that just prints a date. Some newer phones go further: Google's Pixel 10 camera app adds C2PA Content Credentials, a standard for attaching a signed edit history to an image.
How to send a photo so the date sticks
- Keep the original. Don't delete it from your phone after sending. The original file is your best copy.
- Send the file, not a "photo." In WhatsApp, attach it as a Document. By email, send it at full size; decline any resize offer.
- Make the date visible. Use a camera app that stamps the date and time into the image, or write the date in the message and in any report you send.
- Create a record someone else holds. Emailing photos to the other party (or to yourself) on the day they're taken leaves a dated message on a server you don't control.
- Put a series into one document. Ten photos texted one by one get separated, recompressed and lost. One PDF with every photo, its date and its location written underneath travels as a single file.
How to check the date on a photo you received
- iPhone: open the photo in Photos and tap i (or swipe up). You'll see date, time, device and location, if they survived.
- Android: in Google Photos, swipe up on the photo to see its details.
- Windows: right-click the file → Properties → Details → "Date taken."
- Mac: open in Preview → Tools → Show Inspector → the EXIF and GPS tabs.
If those fields are empty, the metadata didn't make it — which tells you something about how the photo was sent, not about when it was taken.
