Remove Adobe Firefly Metadata from Images
Adobe Firefly, Photoshop, and Lightroom embed C2PA Content Credentials into every AI-generated or AI-edited image. This metadata triggers "Made with AI" labels on Instagram, Facebook, and LinkedIn. StripShot removes all Adobe AI metadata at the binary level.
What Adobe Firefly embeds in your images
Adobe is the primary force behind the C2PA standard and the Content Authenticity Initiative (CAI). Their tools embed the most comprehensive AI metadata of any generator. Here is exactly what gets written into your files.
C2PA Content Credentials
The core metadata layer. C2PA (Coalition for Content Provenance and Authenticity) data is stored as JUMBF boxes in JPEG APP11 markers and as caBX/caMs/caSt chunks in PNG files. The manifest contains a cryptographically signed record of how the image was created.
Adobe's C2PA manifest includes: the creator tool (Firefly, Photoshop, Lightroom), the type of AI action performed (generation, inpainting, expansion), a timestamp, and a digital signature chain linking back to Adobe's certificate authority.
This is the data that Instagram, Facebook, and LinkedIn specifically read to trigger "Made with AI" labels on posts.
Content Authenticity Initiative (CAI) markers
CAI is Adobe's broader initiative that wraps around C2PA. CAI data includes provenance information, edit history, and tool attribution. Adobe's Verify website (contentauthenticity.org/verify) can read these markers and display the full creation history of any image.
If you upload an image with CAI data to Adobe's Verify tool, it shows the creation tool, edit steps, and AI generation details. This makes it trivial to identify Firefly output.
Generative Fill and Generative Expand triggers
Using any AI feature in Photoshop (Generative Fill, Generative Expand, Remove Tool with AI, Neural Filters) adds C2PA Content Credentials to the saved file. This happens even if the AI edit was minor, like removing a small object from a real photograph.
This catches many photographers off guard. A real photo edited with Generative Fill gets tagged with AI metadata. Uploading it to Instagram can trigger the "Made with AI" label on what is primarily a real photograph.
XMP and EXIF metadata
In addition to C2PA, Adobe tools write standard EXIF and XMP metadata. The EXIF Software field references Photoshop or Firefly. XMP data contains detailed edit history including which AI tools were used. These are secondary detection vectors that some platforms check.
The photographer problem
Adobe's AI metadata creates a unique problem for photographers. If you use Photoshop's Generative Fill to remove a power line from a landscape photo, the entire image gets tagged as AI-generated. Instagram then labels your real photograph as "Made with AI."
StripShot solves this by removing all C2PA Content Credentials regardless of how minor the AI edit was. Your photograph stays your photograph.
How StripShot removes Adobe Firefly metadata
- JPEG files: Identifies and removes APP11 markers containing C2PA JUMBF boxes. Strips APP1 markers with EXIF Software tags and XMP data referencing Adobe tools.
- PNG files: Removes caBX, caMs, and caSt chunks containing C2PA Content Credentials. Strips tEXt and iTXt chunks with Adobe metadata.
- PSD export: When exported from Photoshop to JPEG or PNG, the C2PA data carries over. StripShot removes it from the exported file.
- Signature removal: The complete digital signature chain linking to Adobe's certificate authority is removed along with the JUMBF manifest.

Adobe Lightroom AI metadata
Lightroom's AI features (Generative Remove, AI-powered masking, Denoise AI) also add Content Credentials to exported files. Lightroom can be configured to always attach Content Credentials, even for non-AI edits.
Check your Lightroom export settings. If "Include Content Credentials" is enabled, every exported photo gets C2PA metadata. StripShot removes these credentials regardless of the source.
Firefly web vs Photoshop vs Lightroom
| Tool | AI metadata | Triggers AI label? |
|---|---|---|
| Firefly web app | C2PA + EXIF + XMP | Yes, always |
| Photoshop (Generative Fill) | C2PA + EXIF + XMP | Yes, always |
| Photoshop (no AI features) | EXIF + XMP only | Usually no |
| Lightroom (AI features) | C2PA + EXIF + XMP | Yes, if Content Credentials enabled |
| Lightroom (manual edits) | Optional C2PA + EXIF | Depends on export settings |
