EasyGlobe runs an independent on-site review. It reads the original and C2PA locally, then sends a resized, metadata-free copy to Hive only when trusted AI provenance is not confirmed. Hive may retain detection data for 14 days by default; actual retention follows its current policy and account settings.

Deepfake is a separate face-manipulation signal; it does not by itself mean the whole image is AI-generated.

How to read the result
0%–30% No strong AI signal; real photos and ordinary screenshots often fall here.
31%–89% Inconclusive; compression, redraws, AI edits, reposted screenshots, and mixed editing appear here more often.
90%–100% The pixel model found a strong AI signal.
100% Verified AI Not a Hive model probability; trusted signed provenance directly confirms the AI origin.

Complete the SynthID-related review on EasyGlobe
EasyGlobe checks C2PA, trusted provenance, and Hive pixel signals on this page. It does not use Google’s private SynthID verifier and never labels a general AI probability as an official Google watermark result.

How the on-site SynthID-related review works
Upload the original image and EasyGlobe automatically completes four steps while keeping watermark, provenance, and probability evidence clearly separated.
-
Step 1
Upload the source image
Use a JPG, PNG, WebP, or AVIF source file up to 50 MB, preferably before screenshots or repeated reposting.
-
Step 2
Read C2PA locally
The browser checks signed origin, the generating tool, and explicit AI-use assertions before sending an analysis copy.
-
Step 3
Prepare a private copy
If trusted AI provenance is not confirmed, the page resizes the image, removes metadata, and sends an actual JPEG or WebP copy.
-
Step 4
Review separate signals
Compare trusted provenance, AI probability, source candidates, and Deepfake evidence. No probability is an official Google watermark result.
If you only have a screenshot, crop closely around one image and avoid a collage. Repeated editing, compression, cropping, or very small changes can make the result inconclusive.
What this SynthID review page checks
SynthID is a watermarking system for AI-generated media. This page is built around the specific search intent behind SynthID checker, SynthID detector, and Google AI watermark queries.
Last updated: July 28, 2026
Google AI source clues
Summarizes structured AI-use assertions from the active C2PA Manifest without claiming to read a private watermark.
C2PA fallback
Reads Content Credentials locally first, because signed provenance can provide strong origin evidence.
No-signal context
Separates no SynthID found from not AI-generated, which is the most important interpretation gap.
What SynthID can and cannot detect
SynthID is Google’s private watermark technology. EasyGlobe combines C2PA and general pixel-model evidence for screening; it is not an official Google SynthID verification.
Can help identify
- Images whose active C2PA Manifest is Trusted and contains an explicit generative-AI digitalSourceType.
- Cases where a positive signal should be escalated for provenance review.
Cannot prove
- That an image is human-made when no SynthID signal is found.
- That unsupported AI generators, screenshots, or heavily recompressed files are clean.
- Whether the visual claim in an image is true, misleading, or edited after generation.
How to interpret SynthID results
Treat SynthID as a high-value provenance signal, not a universal AI detector. The result is strongest when the watermark or signed provenance is found, and limited when no supported signal is available.
Provenance found
A Trusted active C2PA Manifest with an explicit generative-AI digitalSourceType can provide strong provenance evidence; ordinary brand text does not trigger confirmation.
No provenance found
The current file has no verifiable source statement. It may still come from Google or another AI system, or may have lost signals during editing or reposting.
Inconclusive
Simple images, tiny edits, screenshots, compression, or damaged files can make provenance review less clear. Keep these cases in a manual review workflow.
SynthID vs C2PA vs metadata
AI provenance is easier to understand when invisible watermarks, signed credentials, and ordinary file metadata are reported separately.
Signal
What it can show
Main limitation
SynthID
A private invisible watermark embedded by Google products.
EasyGlobe does not use Google’s private verifier, so an on-site result is not an official SynthID conclusion.
C2PA
Signed provenance, tool names, edit history, and AI-use declarations.
Metadata can be stripped, invalidated, or stored remotely by some tools.
Metadata
File type, dimensions, size, and sometimes camera or editor details.
Easy to remove or rewrite, so it is context rather than proof.

SynthID checker FAQ
Practical interpretation details for Google AI watermark checks.
This page checks C2PA Content Credentials, trusted AI provenance statements, and an independent pixel-based AI probability on EasyGlobe to support reviews related to SynthID and Google AI watermarks.
No. This tool does not use Google’s private SynthID verifier and never presents a Hive pixel score as an official Google watermark result. It provides independent on-site screening and a provenance summary.
No. Missing C2PA or source evidence only means the current file has no verifiable provenance statement; the image could still come from Google or another AI system.
Watermarks are designed to survive common edits, but screenshots, heavy recompression, cropping, format conversion, or repeated edits can still reduce detection confidence.
SynthID is an invisible watermark embedded into generated media. C2PA Content Credentials are signed provenance records that can describe origin, editing history, and whether AI tools were used.
