AI image metadata remover

Where AI image generators hide their metadata

There is no single standard, so the data ends up in several different places:

• PNG text chunks. Automatic1111, ComfyUI and Forge write a parameters chunk containing the complete prompt, negative prompt, seed, sampler, CFG scale, model name and model hash. Anyone who opens the file in a text editor can read it.
• C2PA manifests. A JUMBF box holding a cryptographically signed provenance record. In JPEG it lives in an APP11 segment, in PNG a caBX chunk, in HEIC and AVIF a jumb box.
• EXIF and XMP fields. Generator names appear in Software, UserComment or CreatorTool, plus custom XMP namespaces.

Your prompt is often the most sensitive part. It can contain client names, unreleased product details, or simply a working method you would rather not publish.

What C2PA is, and what removing it means

C2PA Content Credentials are a signed record of how a file was made — which tool, when, and whether AI was involved. They are not a watermark and not DRM. They are closer to a chain of custody, and the signature means tampering is detectable rather than prevented.

Removing a manifest removes the signed history. A verifier then reports the file as having no credentials, which is the same state as any ordinary photo. It does not make the file appear to be something it is not.

There are honest reasons to strip them. A credential can name the account, the tool and the device you used. If you have licensed an image to a client, the embedded chain can also expose your workflow. Read more in C2PA explained, or go straight to the ChatGPT image metadata remover if that is where your images come from.

Where we draw the line

This tool removes metadata. It does not modify your pixels, and it will not implement fingerprint-scrambling designed to defeat AI classifiers. That feature exists elsewhere; we think it makes your image worse in exchange for helping mislead a system built to label content accurately.

Working through a folder of generations rather than one file? The bulk image metadata remover handles them in a single pass.

Be aware of the surrounding rules too. The EU AI Act's Article 50 transparency obligations apply from 2 August 2026, and most large platforms already ask for AI content to be disclosed. Cleaning metadata for privacy is a normal thing to do. Removing a disclosure to pass work off as something it is not is a different act with different consequences.
