What Is SynthID? ↗
Understand Google SynthID, pixel watermarks and why metadata cleanup cannot verify removal.
SynthID vs C2PA: Watermarks and Metadata ↗
Compare pixel watermarks, signed Content Credentials and file metadata before processing images.
Verify Image Exports and SynthID Results ↗
Compare original and exported images with matching file hashes, settings and detector evidence.
Choose the question first
Start with the basics if you want to understand a hidden watermark. Read the comparison when a file contains Content Credentials or EXIF. Use the verification workflow when you already have an original and an exported copy to test. Each guide addresses a different question; metadata presence alone answers none of them completely.
Keep a useful record
Retain the original file, record the source and save the export report. Write down the format, resampling and quality settings for each experimental copy. Match detector screenshots to the exact file tested, rather than relying on filenames that can be reused. An unchanged image preview does not establish that a watermark has disappeared.
Processing and verification are separate
The local workspace inspects supported image containers and creates downloads on your device. External detection is a separate step and can require uploading files to another provider. Review that service before sharing an image. If detection is unavailable, record the result as unverified and preserve the evidence you do have.
This SynthID remover lab does not verify detection or removal. Metadata findings describe file blocks, not image origin.
