Image metadata & C2PA remover
Strip C2PA content credentials, EXIF, XMP and generator fields from PNG and JPEG without touching a single byte of image data.
A photo carries more than most people expect: GPS coordinates accurate to a few metres, camera and lens model and sometimes serial number, capture time, editing software, author and copyright fields. AI-generated images often carry C2PA content credentials naming the model and generation time — occasionally the prompt too. All of it lives in the metadata layer, stored separately from the picture you see.
The tool walks the actual file structure. For PNG it iterates chunks and drops eXIf, C2PA containers and text chunks; for JPEG it walks segments and drops APP11 (the usual JUMBF/C2PA container), other APP segments and comments, while keeping the APP0 JFIF header. Image data is copied verbatim — PNG IDAT and the JPEG scan are untouched, so quality is bit-for-bit identical.
One detail worth calling out: the ICC colour profile lives in JPEG's APP2 segment. It describes how colours should be displayed rather than who made the file, and removing it can shift colours on other devices. It is therefore kept by default, though you can strip it too.

FAQ
Can it remove a SynthID image watermark?
No. SynthID's image watermark is embedded in the pixels and survives cropping, compression and filtering. It is not in the metadata layer, so no metadata tool can touch it. We handle metadata only, and won't claim otherwise.
Does cleaning reduce quality?
No. Image data is never re-encoded — PNG IDAT chunks and the JPEG scan are copied verbatim and only metadata blocks are dropped. That is fundamentally different from "save again", which would add a second round of lossy compression.
Does removing C2PA make the source untraceable?
The in-file manifest is genuinely gone, but C2PA also supports soft binding, where a service re-links content by fingerprint against its own database. No local tool reaches a record on someone else's server.
Why keep APP0/JFIF?
It is JPEG's basic header, describing decode parameters such as pixel density, and carries no identity information. Removing it can stop older software from opening the file.
What about WebP and HEIC?
Currently PNG and JPEG only, which covers the vast majority of cases. For other formats, convert to PNG or JPEG with the site's converter first — conversion itself does not carry the original metadata across.
