Date stamp photos
Put the date each photo was taken onto the picture, read from the camera's own record, on one photo or a hundred. The photos never leave this device.
Add your photos. Each one gets the date its camera recorded.

Saved at the original pixel size, turned upright. All metadata is removed from the new files: the camera date, GPS location and camera model are not copied (only what you chose to stamp is visible on the picture). Your originals are not changed.
Your settings (not your photos) are remembered on this device.
Privacy: the photos are read and stamped in your browser and never uploaded. The camera date is read from the file's bytes on this device, and the stamp is drawn with the browser's own canvas. File names, dates, coordinates and your second line are never sent anywhere.
How to date stamp your photos
- Add the photos. Tap Add photos and pick 1 to 100, or drop them on the box. Each one is read for its camera date at once; a green camera badge means the date came from the photo itself.
- Check the dates. Step through with ‹ and ›, or tap a thumbnail. An amber dot marks a photo that only had a file date; a red ? marks one with no date at all. Type the right date in the box under the preview to change any photo.
- Pick the look. The orange '26 10 17 is the date a 1990s compact camera printed in the corner. The plain formats suit records: 2026-10-17 sorts correctly and cannot be misread between countries.
- Add a line if it helps. An address, a room, a job number. GPS coordinates are added only if you tick the box.
- Download. One photo, or all of them in a ZIP, named after the originals with -dated added.
Where the date comes from
Phones and cameras write the moment of the shot into the photo as EXIF DateTimeOriginal, in the camera's local clock time, for example 2019:07:04 18:30:00. Phones and cameras from about 2017 on also write OffsetTimeOriginal, such as +02:00; when it is there, the page shows it and can convert the time to this device's time zone. A photo without that record falls back to the file's own date, labelled file date, not the camera's, and a pasted picture has neither, so you type its date.
| Format | Date only | With the time |
|---|---|---|
| Retro film stamp | '19 7 4 | '19 7 4 18:30 |
| ISO | 2019-07-04 | 2019-07-04 18:30 |
| Day month year | 4 Jul 2019 | 4 Jul 2019 18:30 |
| US | 07/04/2019 | 07/04/2019 6:30 PM |
A worked example: a 4,032 × 3,024 phone photo turned upright is 3,024 px wide. At size 4 % the lettering is set at 121 px, and a 3 % margin keeps it 91 px from the edges. A 1,200 px wide copy with the same settings gets 48 px lettering 36 px in, so a batch of mixed sizes looks the same throughout.
What it cannot do
- It cannot know the date of a photo whose metadata was stripped. WhatsApp, Signal, Facebook, Instagram, screenshots and many editing apps remove the camera date. Sending a photo "as a document" or by email usually keeps it. Without it you get the file date, which may be the day the photo was saved or downloaded, so check those.
- A stamped date is not proof. Anyone can type any date here or in an editor, so for move-in condition photos, building progress or insurance claims a stamp is a label, not evidence. Keep the untouched originals too, and send them to the landlord, client or insurer on the day: their dated email is the stronger record.
- No video. It stamps still photos only.
- Camera date only from JPEG. PNG, WebP and HEIC files are stamped, but their dates come from the file, not the camera. An iPhone hands Safari a JPEG copy of its HEIC photos, which normally keeps the date.
- It cannot fix a camera with a wrong clock. If the camera's clock was off by a year, so is its date; type the right one.
- Big batches use memory. Photos are drawn one at a time, but the ZIP is built in memory: 100 phone photos make a ZIP of about 250 to 500 MB. If a phone browser gives up, download in smaller batches. iPhone Safari caps a canvas at about 16.7 megapixels; a bigger photo is then saved smaller, and the page says so.
Questions
How do I add a date stamp to iPhone photos without an app?
The iPhone Camera has no setting that prints the date on photos. Open this page in Safari, tap Add photos, then Photo Library, and select up to 100. Each photo is stamped with the date its EXIF data says it was taken. Tap Download all as ZIP, or Download this photo; Safari saves to Files (Downloads), and from a single photo there Share → Save Image puts it in Photos.
How do I date stamp photos on Android or Samsung?
Open this page in Chrome, tap Add photos and pick them from the gallery (long-press to select several). The date is read from each photo. Recent Samsung Galaxy phones also have a Watermark option in Camera settings that adds the date to new photos, but it cannot add it to photos you already took; this page can.
How do I date stamp photos on Windows or Mac?
Open this page in any current browser, select the photos in File Explorer or Finder and drag them onto the box. Downloads go to your Downloads folder; Windows and macOS both open the ZIP with a double-click.
Why does a photo say "file date, not the camera's"?
That photo has no camera date inside it. Messaging and social apps remove it from photos they send or post, and so do screenshots. The page then uses the date the file was last saved, which can be the day it was downloaded rather than the day it was taken. Check it and type the right date in the box under the preview.
Is a date stamp proof of when a photo was taken?
No. Any date can be typed in here or in any editor, so a landlord, insurer or court may treat a stamped date as a label, not as evidence. For move-in or damage records, also keep the untouched originals (which carry the camera date), and send them to the other party on the day. To see everything a photo records, open it in EXIF Viewer.
