Claude watermark remover
Claude signs the images it generates with a C2PA provenance record. This finds it, shows you it, and rebuilds the file without it.
What this looks for
Add a PNG, JPEG or WebP and every metadata block in it is listed here by name and byte count, before anything is removed. It looks for EXIF, XMP, IPTC and Photoshop resource blocks, free-text comments, modification timestamps, and C2PA Content Credentials. The colour profile is left alone on purpose, because deleting it changes how the image looks and it says nothing about you.
A watermark encoded into the pixels themselves, such as SynthID, is a different mechanism and is not something this or any metadata tool can remove.

What Claude's watermark on an image actually is
Anthropic marks generated content two different ways, and only one of them lives in a file's bytes. Images get signed provenance metadata following the C2PA standard — a manifest recording that the image was produced by Claude, carried in a dedicated chunk of the PNG, JPEG or WebP container. That is a labelled block like any other, so this tool finds it by walking the container, reports its size, and writes out a new file built from the blocks that remain. The pixels are copied across untouched, so the image is byte-identical where it counts. Anthropic's own documentation confirms the consequence in plain terms: it says a mark may no longer be detected once metadata has been stripped by format conversion, re-saving, screenshots or other means.
What it cannot do
- This works on image files. Text is a separate mechanism, handled by the text tools here.
- An absent C2PA manifest is not evidence that an image was not AI-generated. Provenance metadata is trivially removable in either direction, which is a limitation of the standard rather than of this tool.
- PNG, JPEG and WebP only. Other formats are reported as unsupported and handed back untouched rather than guessed at.
Questions people actually ask
- Does Claude watermark the images it generates?
- Yes, with a signed C2PA provenance record embedded in the file. Anthropic documents this: generated files carry signed metadata following the Coalition for Content Provenance and Authenticity standard, covering formats including PNG, JPEG and SVG. It is a record attached to the file, not a visible mark on the picture.
- Does this remove Claude's text watermark too?
- No. Anthropic marks text by a completely different mechanism, described in its documentation as imperceptibly woven into the text rather than added as hidden characters. Nothing that operates on a file's metadata, or on the characters in a string, has anything to work with there. Treat any tool claiming otherwise with suspicion.
