Supports PNG, JPEG, and WebP up to 50 MB · Inspects C2PA, EXIF, XMP, IPTC, and AI prompt chunks
How Our Local AI Watermark Checker Works
Every byte stays on your device. Inspect headers or clean files in seconds.
1. Drop an Image or Paste Text
Open any JPEG, PNG, or WebP file, or paste copied text. You can also load our built-in sample files to test immediately.
2. Inspect Hidden Signals Locally
We parse binary JPEG APP1/APP11 segments, PNG tEXt/iTXt/c2pa chunks, WebP EXIF/XMP blocks, and zero-width Unicode code points in memory.
3. Strip Metadata & Download Clean
Re-encode images via browser Canvas to remove EXIF, GPS, and C2PA manifests, or copy cleaned text without invisible tracking characters.
What Signals Can Be Checked in a Browser?
Understanding the difference between metadata provenance, hidden text characters, and pixel-level watermarks.
C2PA Content Credentials (JUMBF)
Reads JPEG APP11, PNG c2pa/caBX chunks, and XMP claims embedded by OpenAI, Adobe Firefly, and compliant cameras.
AI Generator Tags & Prompts
Detects Stable Diffusion parameters, ComfyUI workflows, IPTC DigitalSourceType (trainedAlgorithmicMedia), and software tags.
EXIF & GPS Privacy Leaks
Flags camera models, timestamps, creator names, and GPS coordinate blocks before you share photos publicly.
Invisible Unicode Text Watermarks
Highlights U+200B zero-width spaces, U+200D joiners, U+FEFF BOMs, non-breaking spaces, and directional marks.
100% Client-Side Privacy
All inspection and Canvas re-encoding happen locally inside your browser tab. No server storage, no queues.
Honest Scope on Pixel Watermarks
Cryptographic pixel watermarks like Google SynthID cannot be reliably verified by client-side JS and require Google's official portal.
Dedicated Cleaning & Verification Tools
Jump straight to the workflow you need.
AI Metadata Cleaner
Strip EXIF, GPS, XMP, PNG parameters, and AI generation headers from photos in your browser.
