Remove EXIF data

EXIF is the block your camera writes into a photo: the model, the lens, the exposure, the exact moment of capture, and often the coordinates. This removes it and shows you the before and after.

What EXIF actually stores

The core of EXIF is a TIFF structure with three parts. IFD0 holds the maker, model, orientation, software and copyright. The Exif sub-directory holds the photographic detail: shutter speed, aperture, ISO, focal length, lens model, flash state and the original capture timestamp, often down to the sub-second. The GPS sub-directory holds latitude, longitude, altitude and a UTC timestamp.

Many cameras also write a MakerNote — a proprietary, undocumented blob that can run to tens of kilobytes and may include the shutter actuation count or a body serial number. It is removed along with everything else.

Why stripping EXIF is lossless

In a JPEG, EXIF lives in an APP1 marker segment that sits before the compressed scan data. Removing it means dropping that segment and writing the remaining segments plus the untouched entropy-coded scan back out.

The pixels are never decoded, so they cannot be degraded. This is the difference between stripping EXIF and re-saving a photo in an image editor: the latter recompresses and loses quality every time.

The embedded thumbnail

EXIF can carry a small JPEG preview of the image inside it. This matters more than it sounds: if a photo was cropped by software that updated the main image but not the thumbnail, the thumbnail can still show the original, uncropped frame.

Embedded thumbnails are always removed here, including when you edit rather than clean, since keeping one after a change risks leaking the earlier version.

Frequently asked questions

Does removing EXIF delete the GPS location?

Yes. GPS is a sub-directory inside the EXIF structure, so removing EXIF removes the coordinates, altitude and GPS timestamp with it. The before/after report states explicitly whether GPS was present and whether it is gone.

Can PNG files contain EXIF?

They can. PNG gained an official eXIf chunk in 2017, and it is read and removed here. PNG more often carries text chunks (tEXt, zTXt, iTXt) holding software names, authorship or an XMP packet, and those are handled too.

Will my photo still be rotated correctly?

With a quick clean, yes — the orientation tag is written back on its own, with no other EXIF data alongside it. A full clean removes it as well, so a photo taken in portrait may need rotating afterwards.

Is a MakerNote removed too?

Yes. Because it is proprietary and undocumented it is not displayed field by field, but it is reported by size in the analysis and removed in full when cleaning.
