A free online C2PA remover
BeforeShare reads C2PA Content Credentials manifests directly from JPG, PNG, and WebP files and shows the exact provenance, prompt, model, and creator-tool fields it finds before anything is removed.
AI METADATA CHECK
Remove C2PA & AI metadata before you share
See whether a supported file contains explicit AI, prompt, tool, or C2PA metadata. Review the exact evidence first, then download a cleaned copy — all locally in your browser.

Metadata onlyBeforeShare removes hidden metadata only. Any text, names, signatures, and images you can see in the file stay exactly as they are.
A clean result is not proof
The absence of an explicit marker cannot prove that a file was not AI-generated. Metadata can be absent, removed earlier, or stored in an unsupported location.
Your file stays on your device
Inspection and cleaning run locally in your browser. No account is required and the file content is not sent to our server.
What Is AI Metadata in Files?
AI tools can embed hidden provenance or tool data inside generated images, PDFs, and documents. These fields can identify which AI tool generated the file, the model or app used, prompt text, workflow settings, timestamps, C2PA content credentials, PDF document properties, and DOCX author fields.
C2PA / Content Credentials
C2PA is provenance metadata attached to a media file. It can identify the issuing tool, edits, signing information, and history when a compatible credential is embedded.
Prompt and model metadata
Some generators and workflows store prompt text, negative prompts, seeds, samplers, model names, checkpoints, LoRA names, or workflow JSON in XMP or PNG text fields.
Visible watermarks
A visible label, logo, signature, or platform badge is part of the image pixels. Metadata cleanup does not remove visible content.
What Changes When You Clean the File
What stays
The visible subject, dimensions, edits, and crops remain. JPEG files are re-encoded, so file bytes and compression can change even when the picture looks the same.
What goes
Hidden EXIF, XMP, IPTC, PNG text chunks, creator-tool fields, timestamps, model settings, and content-credential metadata are removed when they are embedded in supported formats.
What to review
If the image visibly contains a watermark, signature, prompt text, username, or private detail, remove that separately before sharing.
Supported File Types and What We Check
Images
JPG, PNG, and WebP files can carry EXIF, XMP, IPTC, PNG text chunks, Content Credentials, creator-tool fields, prompts, seeds, and model names.
PDF reports
AI-generated PDFs commonly keep Title, Author, Subject, Creator, Producer, Keywords, timestamps, and sometimes XMP metadata.
Word documents
DOCX outputs can include creator, last modified by, company, manager, revision count, editing time, template, and app version fields.
AI Metadata FAQ
How do I remove C2PA metadata from AI generated images?
Drop your AI-generated image into the tool above. BeforeShare reads the file in your browser, reports C2PA content credentials and other readable metadata, then creates a clean copy without supported metadata containers. No upload or software installation is required.
How to remove content credentials from an image?
Content Credentials use C2PA provenance data. For supported JPG, PNG, and WebP files, BeforeShare creates a newly encoded copy without the metadata containers it detected. Re-encoding can change file bytes and JPEG compression.
How do I clean ChatGPT image metadata?
Images created with ChatGPT or DALL-E embed C2PA Content Credentials that identify them as AI-generated. Drop the image into the tool above: BeforeShare shows the embedded manifest, then creates a clean copy without it — all locally in your browser.
Does this remove visible AI watermarks from images?
No. BeforeShare removes hidden metadata only — C2PA manifests, content credentials, EXIF, XMP, and IPTC fields. Visible watermarks, logos, signatures, or text baked into the image pixels are part of the picture itself and require image editing to remove.
Does the image get uploaded to a server?
Never. BeforeShare processes everything locally in your browser using JavaScript. Your file stays on your device — we cannot see it even if we wanted to.
