Remove EXIF Data From Photos and See What They Reveal

How to use the Remove EXIF Data From Photos and See What They Reveal

1. Add your photosDrop up to 50 photos on the box, or choose them from your device. Each photo gets its own report right away. Nothing leaves your device.
2. Read the reportEach report says what the photo reveals, such as the place, the device, and the time, and rates it from no risk to high risk. The details are grouped, and each risky group explains why it matters.
3. Check the hidden previewIf the file holds a small preview image, it is shown next to the photo. If the two look different, the preview may reveal what was cropped out or edited afterwards.
4. Choose what to keepThe recommended settings keep the rotation, so the photo is not shown sideways, and the color profile, so colors stay the same. They also remove extra data stored after the picture, such as a Motion Photo video.
5. Clean, check, and downloadPress the button to remove the hidden data. Each result lists what was removed and what was kept, shows the picture fingerprint, and confirms a fresh scan finds nothing identifying. Download each photo, or all of them as a ZIP.

What is hidden inside a photo

A photo file is the picture plus several separate blocks of information. The best known is EXIF, which cameras and phones fill in at the moment you take a picture. Editing programs add their own blocks, and some files also carry data that is not part of the picture standard at all. Because these blocks are stored apart from the picture, they can be read, changed, or removed without changing a single pixel.

The Library of Congress describes EXIF as the standard way digital cameras store capture details inside image files. In practice, a photo can hold several layers at once.

• EXIF: camera make and model, lens, exposure settings, date and time, and often GPS coordinates, plus owner names and serial numbers on some cameras.
• XMP: an XML block written by editing programs. It can hold titles, descriptions, creator names, edit history, and a record of the software used.
• IPTC: caption, keyword, creator, city, and country fields used by news and stock-photo workflows.
• Maker notes: private data from the camera maker. Each maker uses its own format, so no tool can read all of them.
• A hidden preview image: a small copy of the photo stored inside the EXIF block.
• Extra data after the picture: for example the video in a Motion Photo, or extra images such as depth maps.
• Text notes in PNG files, including the prompt and settings that some image generators write.

What a photo can reveal about you

Each field can look harmless on its own. Together they answer questions you may not want answered. GPS coordinates show where the photo was taken, often to within a few meters, and for a photo taken at home that usually means your address. The date and time show when you were there. The device model and serial number are unique to your camera or phone and can connect separate photos to the same owner.

The report ranks what it finds so you can see which items matter. Location, serial numbers, and names of people rate as high risk. Dates and times rate as medium. The camera model and software rate as low, and settings such as aperture and ISO carry no risk. A photo's overall rating is the highest rating among its fields.

• Where it was taken: coordinates, altitude, the direction the camera faced, and place names added by editing programs.
• Who or what took it: the owner name, the artist, the camera serial number, and the lens serial number.
• When it was taken: the date, time, and time zone.
• How it was made: the software used, edit history, and any signed Content Credentials.

The hidden preview problem

Many cameras save a small preview of the photo inside the EXIF block, so that file browsers can show a thumbnail without decoding the whole picture. When you later crop, blur, or otherwise edit the photo, some programs update the picture but leave the old preview as it was. The preview can then still show the original, including the part you cropped away.

This tool pulls the preview out and shows it next to the photo. It compares the two and tells you when they differ, or when the preview has different proportions from the photo, which usually means the photo was cropped. Cleaning always removes the preview. The comparison is an estimate based on a small grayscale copy of each image, so look at the two pictures yourself when it matters.

Motion Photos and other data after the picture

Android's Motion Photo format stores a still image, such as a JPEG, HEIC, or AVIF file, with a short video attached after the image data. The video sits at the end of the same file, and an XMP block describes where each part starts. When you look at the file as a photo you see only the still, so it is easy to share a video, often with sound, by accident. Other cameras store depth maps or extra images in the same place.

The tool measures how much data follows the end of the picture and says whether it looks like a video, more images, or something else. The recommended setting removes it. If you want to keep a Motion Photo as a Motion Photo, switch that option off.

Why this tool does not re-encode your photo

A common shortcut is to draw the photo onto a canvas and save it again. That removes the metadata, but it also compresses the picture a second time, which lowers quality, and it can change how the photo is rotated. This tool takes a different route. It reads the file's structure, copies the picture data byte for byte, and writes the file back without the hidden blocks.

Rotation needs care. Many phones store pictures in one fixed direction and add a one-number orientation tag that tells programs how to turn them. If that tag is removed, the photo can appear sideways. By default this tool keeps a tiny EXIF block holding only the orientation number, so the photo stays upright and nothing else is kept. You can switch this off if you prefer.

After cleaning, the tool fingerprints the picture data before and after with SHA-256 and requires the two to match. It reads the cleaned file again from scratch and lists whatever remains. If anything does not check out, it refuses to give you the result.

• JPEG: the picture, color-profile, and Adobe color-mode segments are copied. Metadata segments are dropped. The Adobe segment is never removed, because it affects how colors decode.
• PNG: picture chunks are copied with their checksums. Text, EXIF, and time chunks are dropped.
• WebP: picture chunks are copied. The EXIF and XMP chunks are dropped, and the header flags and file size are corrected.
• HEIC, HEIF, and AVIF: the bytes of the EXIF and XMP items are overwritten in place, so no position in the file moves. The tool checks that no byte outside the metadata changed.

What cleaning cannot remove

Cleaning removes hidden data, not what the picture shows. A street sign, a reflection in a window, a face, or a view that someone can recognize stays in the image. The file name stays too, so rename files that include a name or a place. Information that other programs keep outside the file, such as your device's own record of when the file was created, is not part of the file and is not changed.

Be careful about how you share. Some services remove metadata when you upload a photo and others keep it, and their behavior can change. Cleaning the photo yourself before it leaves your device, and scanning the result once, is more reliable than assuming a service will do it.

Limits and accuracy

• It supports JPEG, PNG, WebP, HEIC, HEIF, and AVIF. TIFF, camera RAW, GIF, and video files are not supported.
• It cleans everything except what you choose to keep. It cannot remove only the location, because the same information can also sit in XMP data, maker notes, and the hidden preview. Partial removal gives a false sense of safety.
• Maker notes are removed as a whole. Each camera maker uses its own format, so the tool shows their size and maker but cannot list every field inside.
• Small preview images used as part of the picture, such as the thumbnails stored by some HEIC files, count as picture data and are not changed.
• The hidden-preview comparison is an estimate. It can call two images different after heavy editing, and it cannot be done for formats your browser cannot display.
• Files larger than 100 MB are skipped, and up to 50 photos can be added at once.
