# How to remove metadata from an image

Source: https://passreal.com/how-to/remove-image-metadata

Every photo carries hidden metadata: GPS position, camera model, date and editing software. To remove it on Windows, right-click the file, open Properties, Details, and choose Remove Properties and Personal Information. On Mac, Preview can drop the location. On any system, ExifTool deletes everything with exiftool -all= file.jpg. AI images hold extra provenance fields, which PassReal strips in one upload.

## What metadata is hiding in your photo

A picture file is more than pixels. The camera or app writes a block of data
next to them, and it travels with the file every time you send it.

The common fields are easy to list. GPS coordinates show where you stood. The
camera make, model and lens show what you used. The date and time show when.
The Software field names the editor, and some phones add a serial number. If
you post a photo from your home, the coordinates can point to your front door.

Three standards hold this data. EXIF is the one cameras write. IPTC is used for
captions, credits and rights. XMP is a flexible block that editors such as
Photoshop and Lightroom add. A cleaning tool has to cover all three.

## Remove it with the tools you already have

Windows is the simplest. Right-click the file, open Properties and go to the
Details tab. At the bottom, choose Remove Properties and Personal Information.
You can create a clean copy or strip the file in place. It works for the
common fields, but it does not touch every XMP entry.

On a Mac, Preview shows the inspector under Tools. The GPS tab has a button to
remove the location. That clears the position only. Date and camera data stay.

On an iPhone, the position is the part you can control from the share sheet.
Tap Options at the top and switch off Location, and the copy you send carries no
coordinates. The camera and date fields still travel with it.

On Android, Google Photos lets you edit or remove the location from the details
panel. Other gallery apps have a similar control. Check what the shared copy
holds afterwards, because apps differ.

GIMP and Photoshop can drop metadata at export. In GIMP, untick the EXIF, XMP
and IPTC boxes in the export dialog. In Photoshop, the Save for Web path
leaves out most of it. Test the result, as the exact behaviour depends on the
version.

## Remove everything with ExifTool

ExifTool is free, runs on Windows, Mac and Linux, and is the most complete
option. One command clears every field it can write:

`exiftool -all= file.jpg`

It leaves a backup named `file.jpg_original` next to the result. Run
`exiftool file.jpg` again to read what is left. You can process a whole folder
with `exiftool -all= folder/`. It is a command-line tool, so it takes a few
minutes to get used to, but nothing else cleans as deeply.

## What changes when the image is AI-generated

An AI image carries everything above plus provenance data. Generators write a
C2PA manifest, an IPTC digital source type and often an XMP entry naming the
tool. Platforms read those fields to decide whether to show an AI label. On
one Gemini export we counted 174 such markers. The full list is in our guide to
[removing AI metadata from an image](/guides/remove-ai-metadata).

The system tools above rarely reach all of these. ExifTool gets most of them,
but you should read the file again afterwards.

## The one-upload method for AI images

PassReal removes every metadata family in one pass: C2PA, the IPTC digital
source type, XMP, PNG text chunks and the EXIF software tag. On the Gemini
export the marker count went from 174 to 0. It then adds camera sensor grain
and lens fringing, smooths the high frequencies and saves a JPEG with the tables
and EXIF fields of a real phone. SSIM and PSNR are shown for each image, so you
see what changed. The first three images are free.

Two limits are worth stating. PassReal does not remove a visible watermark, such
as a logo or text drawn on the picture. And SynthID, the watermark Google
places in the pixels, is built to survive edits, so we do not claim to remove it.

If a public AI image detector flags an image you paid to process, email us within
14 days with the result and we refund the payment in full. The terms are in
section 7 of the [Terms of Service](/terms#guarantee).

## How to check that it worked

Do not trust the tool that did the cleaning. Open the new file in a second
viewer and look at each group: GPS, camera, dates, software, XMP, IPTC and any
C2PA or JUMBF block. If a field remains, run the step again on that group.
Keep the original file somewhere safe, because the cleaned copy cannot give back
what it no longer holds.

## Questions

### What is the difference between an EXIF remover and a metadata remover?

EXIF is one family of metadata, the one cameras write. A full metadata remover also clears IPTC, XMP and, for AI images, C2PA and PNG text chunks. A tool that only removes EXIF can leave the rest in place.

### Does removing metadata reduce image quality?

No. Metadata is stored beside the pixels, so deleting it does not touch them. Quality only changes if the tool also re-compresses the picture. PassReal measures SSIM and PSNR for every image it processes and shows you both.

### Will social networks remove metadata for me?

Many platforms strip location data from the public copy, but they may read the file first, and the rules differ by service. Do not count on it. Clean the file yourself before you upload.

### Is a screenshot a safe way to remove metadata?

A screenshot is a new file, so it does not copy the original fields. It does lower resolution, and some phones add their own tags. It is a quick fix, not a clean one.

### Do I still have to say an image is AI-generated?

Platform rules and local law can require it. Removing metadata does not change that duty, so check the rules of the place where you publish.
