IPTC Remover — Strip Captions, Credits & AI Source Type Free

What it removes

IPTC metadata — originally built for photojournalism (captions, keywords, photographer credit) — now also carries a field called DigitalSourceType that several platforms and generators use as a simpler, unsigned alternative to a full C2PA manifest for flagging AI-generated content.

Why IPTC matters for AI detection specifically

Following IPTC's own 2024 guidance, tools including Midjourney and Shutterstock's AI products adopted IPTC's DigitalSourceType field to declare synthetic or algorithmically-generated content — a lighter-weight alternative to managing C2PA's certificate infrastructure. Platforms that check for AI indicators often read this field as well as, or instead of, a C2PA manifest.

What's typically inside

DigitalSourceType — a standardized value like trainedAlgorithmicMedia marking AI involvement.
Caption, keywords, and byline — traditional photojournalism fields, still in wide use for ordinary (non-AI) photos.

AiEraser's View mode flags IPTC blocks alongside EXIF, XMP, and C2PA data, so you see the complete picture in one scan.

Frequently asked questions

Is IPTC's AI flag as strong a signal as C2PA?

It's simpler and unsigned, which makes it easier to implement but also easier to strip or spoof than a cryptographically signed C2PA manifest. Platforms generally treat it as a supporting signal alongside C2PA, not a replacement.

Will removing IPTC data remove photo credits I want to keep?

Yes — AiEraser's Remove mode strips all metadata at once via re-encoding, including caption/byline fields. If you need to keep author credit on a file, don't run it through Remove mode, or re-add the credit afterward through your own workflow.
