Frequently asked questions

You may remove metadata from content you created or have the rights to modify. Removing markers from someone else’s work can create legal risk, including under copyright law. OutWatermark AI is for your own content only. See the Compliance page and seek legal advice when needed.

Purification uses controlled transformations and re-encoding to weaken latent signals such as SynthID. It cannot guarantee removal because SynthID is designed to resist transformations. Removing C2PA, EXIF, and XMP metadata is complete and lossless.

The browser analyzes JPEG, PNG, and WebP, plus top-level C2PA boxes in MP4, MOV, AVIF, and HEIC containers. Surgical cleanup supports the same formats; image purification supports JPEG, PNG, and WebP.

No. Surgical cleanup removes only metadata bytes and does not resample the rest of the file. The image remains pixel-for-pixel identical. Optional latent-signal purification intentionally re-encodes the image.

No. Analysis and cleanup run entirely in your browser. The file never leaves your device, no upload or storage occurs, and it is never used to train a model.

C2PA Content Credentials are signed metadata attached to a file. Platforms can strip them. SynthID is a latent signal embedded in pixels or audio and is designed to survive transformations, but it carries less context. OpenAI combines both on images.

Social platforms often rewrite uploads for compression, storage optimization, and privacy. That process does not always preserve metadata. The C2PA specification acknowledges that provenance metadata can be removed.

Yes. AI watermark detection, metadata removal, and the available local cleanup tools are free and require no account.
