How to Check and Prove When a Photo Was Taken (iPhone, Android, PC)

Last reviewed October 5, 2026 · 9 min read · By the PEA team (Lumina Spark)

Short answer: To check when a photo was taken, open its info panel: Info in Photos on iPhone, About in Google Photos, Properties > Details on Windows, or the Inspector in Preview on a Mac. To prove it, that date isn't enough, because it comes from the device's clock and can be edited in a few taps. Keep the original file untouched and back the date up with records you don't control: a dated email or upload, a trusted timestamp, or a photo signed at capture.

How to check when a photo was taken

On iPhone

Open the Photos app, tap the photo, then swipe up or tap the Info button. Apple says this panel can show the device that took the photo, the date and time it was taken, camera settings, where it was taken and, for a photo shared with you, who shared it.

Note the Adjust link: Apple's guide explains how to change a photo's date, time or location (More > Adjust Info), even for a batch at once, and how to Revert to the original.

On Android (Google Photos)

Open Google Photos, tap the photo, then tap More > About, or swipe up. The date and time appear with an Edit button beside them. Google notes that an edited date shows in Google Photos, but if you share or download the photo it may show the original date and time saved by your camera, so the app and the file can disagree. Other gallery apps usually have a similar Details or Info option.

On a Windows PC

Right-click the file, choose Properties, and open the Details tab. Look for "Date taken," which Microsoft's documentation describes as the date read from the camera in the file's EXIF data. The Created and Modified dates on the General tab describe the file on that computer, such as when it was copied there, not the photo. A blank "Date taken" may mean the metadata was removed along the way.

On a Mac

Open the photo in Preview and click the Info button to open the Inspector. Apple says the More Info tool shows information about the image in different formats and about where the photo was taken. For a camera photo, the original date and time are usually listed in its EXIF section.

Photos received in WhatsApp, iMessage or other apps

  • The time next to a message is when it was sent, not when the photo was taken.
  • iMessage: Apple says sharing a photo from Photos on iPhone includes its metadata, such as date and time, location and device, though the sender can adjust what's shared. A photo received in Messages may still carry its capture date; open it in Photos and check Info.
  • WhatsApp and other apps may compress images and remove some or all metadata; NIST notes that metadata is often stripped when files are shared. If the date matters, ask the sender for the original file, for example by email or a cloud link.

Why the date on a photo is weak proof

  • It comes from the device's clock. The photo gets whatever date the clock says. On an iPhone, anyone can turn off Set Time Automatically and pick another date before taking a picture.
  • It can be edited later. Apple and Google build date editing into their photo apps, and other tools can rewrite the date inside the file. NIST warns that anyone copying or editing a file can manipulate or falsify its metadata.
  • It is easily lost. Uploads, messaging apps, screenshots and format changes can strip it.
  • Even Apple says so. Introducing a photo-verification feature in September 2026, Apple wrote that a timestamp from the phone's operating system isn't enough for real-world assurance.

So treat the date as consistent or inconsistent with your account, not as proof. Equally, an odd date isn't proof of fakery: clocks get set wrong and time zones change when you travel. For more on metadata, see how to check a photo before using it as evidence.

Evidence that holds up better

Keep the original file untouched

Keep the file from the device that took it, not a screenshot or a copy forwarded through a chat app, and work on copies. Note where, when and from whom you got it, and record a hash (such as SHA-256), a fingerprint of the file's exact contents that lets you show later it hasn't changed. A hash doesn't fix a date, but it makes everything below easier to check.

Records made by someone else at the time

Often the simplest strong evidence is a dated record held by a third party: the photo emailed to someone, uploaded to a cloud service or shared album, or sent to your landlord or insurer on the day. These records sit on someone else's systems, so they are hard to backdate, and the recipient can confirm them. They show the photo existed by then, not when it was taken.

Trusted timestamps (RFC 3161)

A time-stamping authority (TSA) is an independent service that signs a token linking a hash of your file to the current time. The RFC 3161 standard describes this as evidence that the data existed before a particular time.

That wording matters. A trusted timestamp shows the file existed no later than the stamped moment and hasn't changed since. It does not prove when the photo was taken, or by whom.

Often that is exactly what you need. Say you photograph an apartment on move-in day and have the files timestamped that day. When you move out and the landlord blames you for a scratched floor, the timestamp shows those exact files, scratches included, existed by move-in day. They could have been taken earlier, but not after you moved in. Timing is the catch: a timestamp added a year later proves only that the file existed a year later, so seal photos promptly.

Photos signed at capture

Some newer phones can sign a photo as it is taken, using a time source the user can't change.

  • Content Credentials (C2PA). This open standard attaches a signed record of how a file was created and edited. Google says the Pixel 10 lineup is the first to build Content Credentials into every photo taken with Pixel Camera, and that these phones can add trusted timestamps even offline, using a clock kept in a secure environment, separate from the one the user controls. You can inspect credentials with the Content Authenticity Initiative's Verify tool. The C2PA's explainer notes that credentials don't judge whether provenance information is true, and that they can be removed, so their absence proves nothing.
  • Apple Reference Image. On iPhone 18 Pro and iPhone 18 Pro Max, an opt-in Reference mode in Camera captures signed, securely timestamped sensor data. Apple says it records a lower and an upper bound on capture time from its cryptographic timestamp service and guarantees the photo was taken between them; the lower bound is refreshed about every 15 minutes on average, and the window can be wider if the phone was offline. Preview on a Mac shows the capture time as a range. The mode is off by default, isn't offered in the Camera app in the EU, and reference images can be viewed only on iOS 27, iPadOS 27, macOS 27 or later.

Both help only if the photo was taken that way, and they show what the camera captured and when, not that a scene wasn't staged.

Witnesses and corroborating records

Someone who was there, or saw the photo that day, can confirm the date. So can ordinary records: receipts, tickets, delivery confirmations, your phone's location history if it was on, or historical weather that matches the sky, rain or snow in the picture. Dated details in the frame, such as a newspaper or seasonal decorations, help too. No single item settles it, but together they can make your account hard to dispute.

If the date ends up in court

In US federal courts, Federal Rule of Evidence 901(a) requires the party offering a photo to produce evidence "sufficient to support a finding" that it is what they claim. Three of the rule's examples are worth knowing:

  • A witness with knowledge (Rule 901(b)(1)), such as the person who took the photo testifying when they took it and that it fairly shows the scene.
  • Distinctive characteristics (Rule 901(b)(4)): the photo's contents taken together with the circumstances, such as weather or items in the frame.
  • Evidence about a process or system (Rule 901(b)(9)) that produces an accurate result, which a timestamp or capture-signing record may help support.

Many states follow the federal model and other countries have their own rules, but the practical questions are similar: who took it, on what device, and what independent records support the date? For message screenshots, see how to authenticate text message screenshots for court.

What PEA can and can't do

PEA (Professional Evidence Authenticator), from Lumina Spark in Japan, offers a free check that runs several independent analyses on an uploaded image and shows its findings, separating confirmed facts from concerns, with a grade from 1 to 10. Its certificate fixes the file with a SHA-256 hash and seals it with an Ed25519 digital signature and an RFC 3161 timestamp from a third-party time-stamping authority, which anyone can verify by certificate number on PEA's public verification page. The signature and timestamp are added when the image is checked, so the certificate shows the file existed at that moment and hasn't changed since, which is what you want for move-in photos checked on move-in day. It does not prove when or by whom a photo was taken. Staff see an image only if you request a human review and consent, and free results are deleted after 7 days.

PEA runs in Japanese today and the English version is in early access. If it sounds useful, you're welcome to join the early-access list at our early-access page.
