Stable Diffusion Watermark Remover: Strip Prompts, Seeds & Metadata Free
Remove embedded data from Stable Diffusion and SDXL images free — the prompt, seed, sampler, and model hash baked into your PNGs, plus any provenance or invisible signals a host added. No sign-up, no quality loss, no watermark of our own added.
Files are read on your device and never uploaded. Closing the tab discards them.
What's embedded in Stable Diffusion images?
SD's biggest privacy leak isn't a visible logo — it's the full generation recipe written into the file. Anyone who opens your PNG in an inspector can read exactly how you made it. This tool clears all of it.
Upload a PNG, JPEG, or WebP, or a batch, and download clean copies with the artwork untouched.
SD and SDXL exports from A1111, ComfyUI, and hosted APIs commonly embed the generation recipe — prompt, negative prompt, seed, sampler, steps, CFG, and model hash — in PNG tEXt chunks or EXIF fields. It travels with the file until removed.
Commercial hosts may layer C2PA provenance or invisible pixel-level watermark signals on top, and some add a visible corner mark to the render.
Cleaning strips the generation parameters, provenance records, and supported invisible signals, and clears any visible mark, leaving the artwork exactly as it was.
The signals in a Stable Diffusion image.
- Generation parameters — prompt, seed, sampler, steps, CFG, model hash in PNG tEXt or EXIF
- C2PA-style provenance where a commercial host adds it
- invisible pixel-level watermark signals where present
- Visible corner marks on the render
- Other readable container metadata in PNG, JPEG, or WebP
Four steps, start to finish.
- 01Upload your SD imagesDrag and drop PNG, JPEG, or WebP files from A1111, ComfyUI, or a hosted API.
- 02Review what's detectedThe scan reports the embedded generation parameters, provenance, and any visible mark per file.
- 03Remove the dataOne click clears the prompt/seed metadata, provenance, and supported marks while the artwork stays identical.
- 04Download and verifySave the clean copy and re-scan to confirm the tEXt/EXIF fields are gone.

What this does not do.
Metadata and pixel-level watermarks are different problems. Anything claiming to clear both in one pass is worth reading carefully.
- The browser pass covers metadata fields and the invisible-watermark payload some Stable Diffusion builds attach. Model-specific pixel watermarks are a separate problem handled by the full workflow.
- Files already stripped by a platform on upload may have nothing left to remove, which the scan will tell you.
- Statistical AI classifiers read the image itself and are unaffected by anything removed from the file.
- Very large files process more slowly on some devices, since everything happens locally.
- You are responsible for model licences and disclosure rules when redistributing images.
Watermarks in text work differently.
Everything on this page concerns images, where the mark lives in metadata or in the pixels themselves. Text carries a different family entirely: invisible Unicode characters sitting between the words, which render as nothing and survive every copy and paste.
If that is what you are chasing, the ChatGPT watermark remover reports every hidden character it finds by code point, with versions for Claude, Gemini and Grok. The ChatGPT text cleaner on the homepage runs the whole set of passes at once.
Stable Diffusion Watermark Remover questions.
Does Stable Diffusion put a watermark on images?
Not usually a visible logo — the main issue is the generation recipe (prompt, seed, sampler, model hash) embedded in PNG tEXt chunks or EXIF. Hosted services may add provenance or a corner mark, all of which this tool removes.
How do I remove the prompt and seed from a PNG?
Upload the file and the tool clears the embedded tEXt/EXIF metadata that stores the prompt, seed, and other parameters, leaving the image itself unchanged.
Does this remove visible marks and provenance too?
Yes — any supported visible corner mark and C2PA and embedded signals a host added are cleared along with the generation parameters.
Will cleaning reduce image quality?
No. The artwork is preserved exactly — only the embedded data and supported marks are affected.
Will platforms still detect my SD images as AI?
Removing embedded data stops field-based detection, but statistical pixel classifiers are separate and may still flag synthetic imagery.
Is this Stable Diffusion watermark remover free?
Yes — free, no sign-up, and no watermark of our own added.
