Remove Stable Diffusion Metadata from Images

Automatic1111 stores your Stable Diffusion generation parameters (prompt, negative prompt, seed, CFG scale, sampler, model hash) in a PNG tEXt chunk with the key parameters. In JPEG and WebP exports the same data lives in the EXIF UserComment field. ComfyUI embeds the full node workflow as JSON in PNG tEXt. StripShot removes all of them at the binary level in your browser.

Stable Diffusion interfaces like Automatic1111, ComfyUI, and Forge embed detailed generation parameters into every image. This includes your full prompt, negative prompt, seed, CFG scale, steps, sampler, and model hash. StripShot removes all of it.

What the Automatic1111 parameters text chunk looks like

When you save a PNG from Automatic1111, it writes a tEXt chunk with the keyword parameters directly into the file. The value is a plain text block that anyone can read with Automatic1111's PNG Info tab, ExifTool, or any hex editor. Here is what it looks like:

a detailed fantasy portrait, masterpiece, best quality, intricate details, (bokeh:1.2), sharp focus
Negative prompt: blurry, deformed, ugly, low quality, nsfw, watermark, signature
Steps: 20, Sampler: DPM++ 2M Karras, CFG scale: 7, Seed: 3782615049, Size: 512x768, Model hash: a1535d0a42, Model: v1-5-pruned-emaonly, Clip skip: 2, ADetailer model: face_yolov8n.pt

This entire block is stored in plain text inside the PNG file. StripShot removes the parameters tEXt chunk entirely at the byte level -- no re-encoding, nothing left behind.

What Stable Diffusion embeds in your images

Stable Diffusion itself is an open-source model. The metadata comes from the interfaces used to run it. Each interface stores generation data differently, but most use PNG tEXt chunks and EXIF fields.

How StripShot removes Stable Diffusion metadata

Does local Stable Diffusion trigger Instagram's "Made with AI" label?

Standard Automatic1111, ComfyUI, and Forge do not embed C2PA Content Credentials. Instagram's "Made with AI" label is primarily triggered by C2PA -- so by default, local SD images are less likely to be auto-labeled than images from DALL-E, Adobe Firefly, or Midjourney.

However, Instagram also uses perceptual hash matching: it compares your image against databases of known AI outputs. If your image is similar to a known AI-generated image, it may still be labeled even without C2PA credentials. This affects any image style that closely resembles common AI outputs.

Some Stable Diffusion extensions (including third-party C2PA signing scripts) can add C2PA credentials to SD images. If you use any such extension, your images will trigger the AI label just like cloud-based tools.

StripShot's anti-fingerprint mode (Pro) applies invisible pixel-level changes that completely alter the perceptual hash of your image, defeating hash-based detection without any visible quality change.

Why removing SD metadata matters

Unlike DALL-E and Midjourney, Stable Diffusion does not use C2PA Content Credentials. Social platforms are less likely to auto-label SD images. But the generation parameters are a bigger problem for a different reason: prompt theft.

Anyone who downloads your image can open it in Automatic1111 (using the PNG Info tab) and see your exact prompt, negative prompt, model, seed, and settings. They can reproduce your image pixel-for-pixel. For artists selling AI art, this is a direct business risk.

SD metadata also reveals which model you used. If you trained a custom LoRA or used a specific Civitai checkpoint, the model hash and name are visible in the metadata. Stripping this protects your model choices and training investments.

Forge and other SD interfaces

Stable Diffusion Forge (a popular Automatic1111 fork) uses the same PNG tEXt metadata format. InvokeAI stores generation data in its own metadata format but also writes to PNG tEXt chunks. SD.Next and vladmandic forks follow similar patterns.

StripShot removes all PNG tEXt chunks regardless of the interface that created them. You do not need to know which SD interface was used. All generation metadata is stripped.
