Remove Stable Diffusion metadata from your image

Stable Diffusion stores your full prompt, model name, and seed inside the PNG file by default. Even after you crop and re-save, those text chunks travel with the image. Our pipeline wipes them.

Short answer

To remove the Stable Diffusion watermark, upload your file to Calabi Sanitizer — it strips Stable Diffusion's PNG text chunks with prompt + model info, generator metadata, and the encoder fingerprint, then injects an authentic phone-capture identity (Make, Model, GPS, timestamp). 10 free cleans, no signup, and a forensic proof card shows exactly what was removed. Stable Diffusion content is detected today by Instagram, Reddit, Pinterest, Stock photo sites.

What Stable Diffusion writes into every export

PNG text chunks with prompt + model info

Stable Diffusion writes the prompt, seed, and model name into every PNG.

XMP DigitalSourceType=trainedAlgorithmicMedia

Standard AI flag.

EXIF/XMP generator fields

Model name and software tags written into the file.

Which platforms scan for it

Stable Diffusion content gets detected by: Instagram, Reddit, Pinterest, Stock photo sites. Each platform has its own scanner — but they all look for the same signatures.

How Calabi removes it

Strip the metadata container — ExifTool wipe of every group, including the Content Credentials JUMBF block.
Break invisible patterns — controlled re-encode with light noise injection defeats pixel-domain watermarks.
Strip the encoder fingerprint — bitstream filter removes the editor's signature so the file's encoding profile matches a real phone.
Inject phone identity — Make / Model / Software / GPS / capture timestamp written across every metadata field.
Forensic proof card — same scan platforms use, run on the output. Green pill = clean.

10 free cleans. No card. See the proof before you download.

Frequently asked

How do I remove the Stable Diffusion watermark?

Upload your file at calabilabs.com/app. The pipeline strips Stable Diffusion's PNG text chunks with prompt + model info, generator metadata, and encoder signatures, then injects authentic phone-capture identity. The forensic proof card shows you exactly what was removed before you download.

Does the Stable Diffusion watermark survive cropping or re-encoding?

Yes — that's why it's so hard to defeat with consumer tools. The watermark is embedded in the file's metadata container and encoded into the bitstream. Neither survives a regular crop or basic re-encode unless the tool specifically targets them.

Will the cleaned file still look the same?

Yes. The visible content is preserved. Changes happen at the metadata level (invisible) and at the pixel level (imperceptibly small noise + perspective shifts that defeat fingerprinting but never affect what you actually see).

Which platforms detect Stable Diffusion content?

Instagram, Reddit, Pinterest, Stock photo sites all scan for Stable Diffusion's watermark signatures before a human ever sees the post.
