Remove AI Metadata from Photos and Videos

Where AI metadata hides

"AI metadata" is not one thing. It is several layers of text scattered through a file's structure, and every format stores it differently:

• EXIF — the classic camera metadata block. In an AI image the Software field often names the generator, and fields like UserComment or ImageDescription can carry model and prompt details.
• XMP — an XML-based block that can hold digitalSourceType and trainedAlgorithmicMedia values, which explicitly flag a file as AI-generated.
• IPTC — a press-oriented standard for captions, keywords, and credit fields, which sometimes records generator information too.
• PNG tEXt chunks — plain-text chunks inside a PNG where tools like Stable Diffusion and ComfyUI write their full generation parameters: prompt, negative prompt, sampler, seed, and model name.
• WebP chunks — the equivalent text containers in a WebP file.
• MP4/MOV boxes — metadata boxes in the ISO-BMFF structure that video generators use to store creation and software details.

The exact fields vary by tool. A Midjourney image stores different text than a Firefly image, and a video from Veo differs again. What they share is that the information is written as plain, inspectable text in a known location.

None of this appears in the image itself. It sits in the file's plumbing, invisible on screen but readable by any tool that knows where to look.

What that metadata reveals

The fields are more specific than most people expect. Depending on the generator, an AI photo can expose:

• The generator and model. "Generated with DALL·E 3," "Stable Diffusion," "Midjourney," or a similar label, often in plain text.
• The prompt and settings. For Stable Diffusion and ComfyUI, the raw parameters block contains the full prompt, negative prompt, sampler, seed, and step count — essentially a recipe for the image.
• The date and actions. When the file was created and what edits were applied, up to and including a C2PA manifest with a signed history.

For a personal project this is usually clutter. For a client file it can leak more than you intended — a prompt that describes a confidential project, a model that reveals an internal workflow, a date that contradicts what you told a customer. Either way, it is your metadata to keep or remove.

Video files tell the same story. An MP4 generated by Veo or another model can hold creation and software boxes that name the generator, alongside the same EXIF-style fields in the video track. It is the same kind of leak, just stored in a different container.

How to remove AI metadata

Three steps in OutWatermark AI:

1. Open your file. Drop a JPG, PNG, WebP, MP4, or MOV into the tool. Nothing is uploaded; the file stays on your device.
2. Read the report. The detector lists the EXIF, XMP, IPTC, text chunks, C2PA manifest, and generator signatures it found.
3. Download the cleaned version. Confirm ownership, choose what to keep, and download.

Removal is surgical. The tool deletes the metadata blocks without re-encoding the pixels, so image quality is untouched. And if you want to keep your camera's EXIF data — shutter speed, ISO, lens, GPS — while removing only the AI-specific fields, the keep-exif option does exactly that.

You do not have to trust the report blindly. After cleaning, reopen the file in the detector and confirm the fields are gone — the tool shows you exactly what remains, so you can verify the result rather than assume it.

Why platforms strip this metadata anyway

You are not the only one removing it. Instagram, Facebook, and LinkedIn re-encode uploads and routinely drop EXIF, XMP, and C2PA metadata in the process. We documented the mechanics in how platforms strip C2PA Content Credentials →.

The difference is control. When a platform strips metadata, you get whatever survives its pipeline — and you have no say in which fields disappear. When you strip it yourself, you choose what stays and what goes before the file ever leaves your device.

Your files, your metadata

Behind this tool is a simple principle: the metadata in your files belongs to you. A generator that stamps its name, your prompt, and a timestamp into an image is recording information about your work. Being able to read that record — and remove it if you choose — is basic ownership of your own content.

That is not a license to misrepresent anything. It is the right to decide what your file carries when you share it.

This matters in practice. A freelancer sending a deliverable, a studio publishing client work, or a team sharing internal assets all have reasons to control what travels with a file. The metadata is part of the asset, and you get to decide its final state.

What the tool cannot do

The honest limits, as always:

• It does not remove visible watermarks. A logo overlaid on the image is a pixel edit, not metadata.
• It does not guarantee removal of latent signals. SynthID and similar signals live in the pixels, not in metadata boxes.
• Video cleanup is surgical. The metadata box is removed; the video stream is not re-encoded.

Is removing AI metadata legal?

For content you own or are authorized to modify, yes — it is your data, and the tool requires an ownership confirmation before download for that reason.

Keep the legal duty in view: since August 2, 2026, Article 50 of the EU AI Act requires AI-generated content to be labelled where applicable. Removing metadata does not remove that obligation. See our compliance overview →.

Frequently asked questions

What is the difference between EXIF, XMP, and C2PA?

EXIF and XMP are metadata fields — camera data and XML blocks — that can name a generator or flag AI content. C2PA is a signed manifest: a cryptographically bound record of the file's history. All three are removable, but only C2PA carries a signature.

Can I keep my camera's EXIF data?

Yes. The keep-exif option preserves classic camera fields such as shutter speed, ISO, and GPS while removing the AI-specific metadata.

Which formats are supported?

Full removal for JPEG, PNG, WebP, MP4, MOV, AVIF, and HEIC.

Is it free and local?

Yes. Free, no account, and fully local — files are processed in your browser and never uploaded.
