Description
CheckSynthID is a free online tool designed to verify Content Credentials (C2PA) embedded in JPEG, PNG, and WebP files. This tool operates entirely within your browser, ensuring that your files remain on your device and are not uploaded to any server. It provides a straightforward way to check the provenance of media files by displaying the validation status, signer information, and any associated actions when Content Credentials are present.

The tool is particularly useful for editors, brands, and agencies that need to verify the authenticity and history of media assets before publication or campaign approval. By using CheckSynthID, users can quickly determine whether a file still carries a signed history of its creation or editing, which can be crucial for maintaining brand integrity and avoiding the use of unauthorized or misrepresented content.
CheckSynthID emphasizes its independence and is not affiliated with Google or any SynthID partners. It does not detect SynthID watermarks, which are imperceptible signals embedded by certain AI systems. Instead, it focuses solely on reading C2PA Content Credentials, which are signed metadata that provide a record of a file's provenance.
The tool is free to use and does not require an account, making it accessible for quick checks without the need for lengthy sign-up processes. It is particularly beneficial for newsrooms and marketing teams that need to ensure the authenticity of media assets in a fast-paced environment.
While CheckSynthID provides valuable insights into the presence and validity of Content Credentials, it is important to note that the absence of credentials does not necessarily indicate human authorship. Users are encouraged to use this tool in conjunction with other methods of verification, such as source interviews and additional provenance signals, to make informed decisions about the use of media files.
