📖 What is Blind Watermarking

Blind watermarking invisibly embeds information into images and videos. The image/video looks identical, but data can be recovered with a specialized algorithm.

Key properties:

Invisible: hidden in subtle pixel adjustments — imperceptible
Robust: survives compression, resizing, screenshots, rotation, format conversion and more
No Original File Needed: extraction requires no original file — decode directly

👥 Who Needs This

wmgg is built for individual creators and small teams. Unlike enterprise solutions at thousands per month, we run in your browser, starting at $0.

Photographers / Designers: embed copyright claims — extract to prove ownership if reposted
Content Creators: tag AIGC images, original images, or videos with creator ID — track distribution
E-commerce Sellers: mark product images/videos with store ID — deter competitor theft
Enterprises / Institutions: distribute docs with unique per-recipient watermarks — leaks trace to source
Individual Users: embed personal ID before posting. 100% local — privacy intact

🎬 Video Watermarking

The same invisible signature can be embedded into videos too. Drop or select a video file, and wmgg signs it locally — no upload needed. Signed videos tolerate normal compression and re-encoding, and are exported as MP4 (H.264) for maximum compatibility.

Supported input: MP4, MOV, MKV, WebM, TS and more.
