EXIF metadata, made clear and useful
Exif Expert is a focused toolkit for photo metadata: view, edit, remove, compare and compress EXIF right in your browser — plus a tool that writes a coherent, real-device EXIF fingerprint into a photo.
What is EXIF metadata?
EXIF (Exchangeable Image File Format) is the structured metadata a camera or phone writes inside a photo file, recording how, when and with what device the image was captured.
Most JPEG and HEIC photos carry an EXIF block alongside the pixels. It travels with the file unless it is stripped — which is exactly why it matters for both privacy and authenticity.
What an EXIF block can contain
- Camera make and model — The manufacturer and model of the device that captured the photo.
- Lens and focal length — The lens used and its focal length in millimetres.
- Exposure — ISO, shutter speed and aperture (f-number) chosen for the shot.
- Date and time — When the photo was taken and when the file was created.
- GPS coordinates — The latitude and longitude where the photo was taken, if location was enabled.
- Orientation — How the camera was held, so the image is displayed the right way up.
- Software — The app or editor that last wrote or modified the file.
How Exif Expert works
The free tools — view, edit, remove and compare EXIF, and compress photos — run entirely in your browser. Your images are processed on your own device and are not uploaded to our servers.
The paid Add EXIF tool assembles a coherent metadata set based on real device profiles: camera, lens, OS version, capture time and GPS are kept consistent with one another, so the file reads like a genuine photo from a real phone rather than a random patchwork of fields.
Honest limitations
Metadata alone does not prove that a photo is authentic. EXIF can be added, edited or removed by anyone, so it should be treated as a helpful signal — not as cryptographic proof of origin.
Your privacy
Because the free tools work locally in your browser, your photos never leave your device when you view, edit, remove or compare metadata, or compress images.
We recommend stripping EXIF — especially GPS and timestamps — before sharing photos publicly, since email, messengers and direct file transfers often preserve the full metadata block.
Who uses Exif Expert
- Photographers and editors restoring or correcting lost metadata.
- Sellers preparing clean product photos for marketplaces and listings.
- Privacy-conscious people removing location and device data before sharing.
- Developers and QA testing how their own pipelines read and validate EXIF.
Frequently asked questions
Is EXIF the same as a photo's file name or size?
Is EXIF the same as a photo's file name or size?
No. EXIF is metadata stored inside the file that describes how the photo was taken — camera, exposure, date and GPS. The file name and file size are separate and are not part of EXIF.
Do social networks keep EXIF?
Do social networks keep EXIF?
Most large social networks strip much of it on upload, but email, messengers and direct file sharing frequently keep the full EXIF block, including GPS coordinates.
Are the tools free?
Are the tools free?
Viewing, editing, removing and comparing EXIF and compressing photos are free and run in your browser. Only the Add EXIF tool is paid, at $2 per photo.
Which image formats are supported?
Which image formats are supported?
Depending on the tool: JPEG, PNG, WebP, HEIC/HEIF, TIFF and AVIF. EXIF editing focuses on JPEG, where EXIF is stored most reliably.
