How to Add EXIF Data to a Photo: Hidden Tags or Visible Text?

To add EXIF data to a photo, decide whether you need machine-readable information stored in the file or camera details printed visibly on the image. A metadata editor changes file tags. A camera stamp is part of the picture's pixels. They solve different problems.

EXIF can hold details such as the camera, lens, exposure settings, capture date and location. Which fields exist depends on the original photo. If you want a portfolio or social image that shows those details at a glance, use a visible overlay. If another app needs to read the details, edit or preserve the file metadata instead.

Choose the result you need

• Check what is already recorded: open the photo's information panel or inspect its file. Viewing tags does not change the photo.
• Correct an iPhone photo's date or location: use Apple Photos' Adjust Info controls for the photo library record.
• Write a tag such as artist or copyright: use a metadata editor to write the machine-readable field into the image file.
• Show camera settings on the image: use an overlay such as BatchPad's EXIF stamp. It draws visible text without editing the hidden tags.

First check whether the details are already there

On iPhone, open a photo in Photos and swipe up or tap the Info button. Apple says the panel can show the device and camera details, including lens and shutter speed, when the photo contains them. From the More menu, choose Adjust Info to change the date and time or location. You can select several photos to adjust those fields together, and Apple provides a way to revert the changes.

If the camera, lens or exposure tags are missing, the pixels alone do not tell you with certainty which equipment or settings produced them. Add only values you can verify from a reliable record; do not guess a camera model or shutter speed.

Write embedded metadata when another app needs to read it

For tags such as an author name, description or copyright notice, use a tool that edits image metadata. ExifTool can read and write metadata in many file types. For example, this writes an Artist tag to a JPEG:

exiftool '-Artist=Your Name' \
  photo.jpg
exiftool -Artist photo.jpg

The second command reads the saved value back so you can check it. ExifTool keeps the original by adding _original to its filename by default. Work on a copy anyway, then verify the new file in the software that needs to use the tag. Keep recorded camera settings truthful: changing an ISO tag does not mean the photo was actually captured at that ISO.

Apple's documented controls do not edit arbitrary camera or lens tags. Use a metadata editor for those fields and check its supported tags and file formats.

Put camera details visibly on the image

A visible stamp is useful when viewers should see the camera or settings without opening an information panel. In BatchPad, add an EXIF overlay, choose the fields and layout, adjust its style and position, then preview it across the selected photos. The overlay reads available source-photo details. An on-image value override changes the stamp's text; it does not rewrite the file's hidden EXIF tags.

If you also need the original EXIF in a BatchPad export, turn on the Metadata option and export as JPEG. The current exporter copies the source EXIF into JPEG output when that option is enabled; its PNG path does not copy the source EXIF segment. Preserving the source metadata keeps existing values, but it does not turn the visible stamp into new file tags. Check the exported file before you rely on either result.

Location can be part of a photo's metadata. Before sharing a file with metadata preserved, check whether it includes GPS information and whether you want to share that location.

A quick check before sharing

• Open the exported file and confirm the fields that should be machine-readable.
• View the image itself to check that the visible stamp is legible and accurate.
• Check date, location and GPS fields before sending the original file.
• Keep an untouched copy so you can correct a tag or make a clean version later.

Use BatchPad when you want a consistent camera-details overlay across a photo set. For a name or logo watermark, see the portfolio watermark checklist.
