How C2PA Remover works
This tool helps you remove supported C2PA/JUMBF containers from a distribution copy. It needs no account and does not send the selected file to our server.
Choose the final file you plan to share. Download the new copy after processing and archive the original safely.

詳細ガイド
What does C2PA Remover process?
This utility is designed to remove supported C2PA/JUMBF containers from a distribution copy. Processing stays in your browser, so the selected file is not sent to a Remove AI Labels server.
For JPG, PNG and WebP, the compressed image data stays intact: the tool rewrites metadata structures and does not re-encode the pixels.

詳細ガイド
Choose the right metadata tool
EXIF commonly stores camera, time and GPS details; XMP carries extensible editor data; C2PA/JUMBF carries Content Credentials; and PNG text chunks can hold prompts or workflows. Dedicated tools let you choose a narrower scope.
For privacy, prioritize location and identifying fields. For distribution preparation, archive the source and clean a separate copy.
06
詳細ガイド
Verify before you share
Inspect the source, run the appropriate tool, download the clean copy and inspect it again. The compressed pixel data of a JPG, PNG or WebP remains unchanged apart from removed metadata structures.
For a social upload or a file from a specific generator, continue with the matching platform and export-source guide.

FAQ
よくある質問
Is my file uploaded?
No. Inspection or cleaning runs locally in the browser.
Does this guarantee a platform will remove an AI label?
No. It processes file metadata, while a platform may use pixel watermarks or other signals.
Will JPG, PNG or WebP quality change?
No. The tool rewrites metadata containers without decoding or re-encoding the compressed pixel payload.
Does HEIC preserve the original pixels?
No. HEIC/HEIF must be converted to JPG, making it the explicit decode-and-encode exception.
Which metadata types can the tool process?
Depending on the selected mode, it can inspect or remove supported EXIF, GPS, XMP, IPTC, C2PA/JUMBF and PNG text chunks.
Can I process multiple files at once?
The cleaner supports up to 30 files per batch and 15 MB per file. The checker reads one file at a time for a clear report.
Should I inspect the file again after cleaning?
Yes. Open the downloaded copy in the checker to confirm that the target fields were removed.
Should I keep the original?
Yes. It may contain useful camera, copyright or provenance information.
Can this remove a visible image watermark?
No. A watermark embedded in pixels is part of the image rather than file-level metadata.
