Stable Diffusion Metadata Remover: What SD Embeds and How to Strip It (2026)

Every PNG you generate with Stable Diffusion carries a full record of how it was made. Your prompt, your negative prompt, your model, your LoRA weights, your seed. It's all sitting in the file in plain text. This guide explains exactly what's embedded, why it matters, and how to remove all of it at the binary level.

What Stable Diffusion embeds in every image

SD stores generation data in PNG text chunks (the tEXt chunk type) and, in some pipelines, XMP metadata. The core chunk is labeled parameters and it contains everything needed to reproduce your image exactly.

Fields embedded in the parameters chunk include: full positive prompt, full negative prompt, Steps, Sampler, CFG scale, Seed, image Size, Model hash, Model name, and LoRA weight hashes. This is the most complete generation fingerprint of any major AI image tool. Midjourney, DALL-E, and Firefly embed far less.

Here is what the raw parameters chunk looks like inside a typical AUTOMATIC1111 PNG:

parameters
beautiful portrait, cinematic lighting
Negative prompt: blurry, ugly
Steps: 30, Sampler: DPM++ 2M Karras, CFG scale: 7, Seed: 3847291847, Size: 512x768, Model hash: 6ce0161689, Model name: dreamshaper_8, Lora hashes: "add_detail: a1b2c3"

Anyone who opens your PNG in A1111's PNG Info tab, or in any metadata viewer, reads all of that instantly. This is the biggest privacy leak in AI image generation.

Why Stable Diffusion prompt exposure matters

Your model selection, your LoRA stack, your seed, and your prompt are your intellectual property. If you built a workflow that reliably produces a particular aesthetic, that workflow is inside your PNG. Anyone with your image and a moment of time can reverse-engineer everything.

The parameters chunk is not optional and there is no native SD setting to suppress it. Stripping it after generation is the only reliable solution.

Does SD embed C2PA?

Stable Diffusion itself does not embed C2PA Content Credentials. It is open-source software and has no C2PA signing infrastructure built in. AUTOMATIC1111, ComfyUI, InvokeAI, and Forge all generate PNGs with the parameters text chunk only.

However, DreamStudio(Stability AI's hosted service) may add C2PA to images generated through its API or web interface, since Stability AI is a C2PA adopter. If you used a hosted SD service rather than running SD locally, your image may carry both C2PA and the parameters chunk.

If you are not sure what is in your image, drop it into StripShot before posting. The detection panel shows every metadata field found before you strip.

What you need to strip from SD images

A complete SD metadata removal covers four areas:

StripShot targets all four of these in a single pass at the binary level. No re-encoding, no quality loss, no pixels touched.

How to remove Stable Diffusion metadata

Stripping SD metadata with StripShot takes about ten seconds:

1. 1

   Drop your PNG into StripShot

   Drag and drop your SD-generated PNG directly into the tool. No account required. Processing is 100% browser-side — your file never leaves your device.

2. 2

   StripShot detects the SD parameters chunk

   The detection panel identifies the parameters tEXt chunk, any XMP data, and flags model hash and LoRA hashes found in the file. You can read exactly what is there before stripping.

3. 3

   Strips all PNG text chunks, XMP, and EXIF

   StripShot removes the parameters chunk and all other text chunks at the binary level. XMP segments are also cleared. If the file is a JPEG, EXIF is stripped in the same pass.

4. 4

   Download the clean file

   The output is pixel-identical to your original. Only the metadata bytes are gone. File size shrinks slightly. Image quality is unchanged.
