Next-Gen Capabilities

Built to Outperform Every Market Leader

Dual-engine pixel restoration, batch folder workers, invisible SynthID scrambling, and zero server uploads.

Mathematical Reverse Alpha Blending

Unlike inpainting models that smudge and guess textures, our algorithm subtracts the exact alpha layer to mathematically reveal the original background photons.

Pixel-Exact Reverse Alpha Restoration

Mathematically calculates inverse alpha blending equations to reconstruct authentic original background pixels without softening or generative blur.

SynthID & C2PA Metadata Scrubber

Strips all EXIF, XMP, and C2PA provenance manifests while applying high-frequency spatial dithering to neutralize invisible AI steganographic watermarks.

Full Folder Batch Drops & ZIP Export

Drop hundreds of images or entire directory trees. Process files in parallel and download a clean, structured ZIP archive in 1 click.

Interactive 400% Zoom Loupe

Inspect raw pixel data side-by-side with 1x, 2x, and 4x magnification levels to verify that zero blur, distortion, or artifacting occurred.

Multi-Format Lossless Exporter

Export as lossless PNG, optimized WebP with real-time quality slider, or AVIF with instant live file size comparison.

IndexedDB "Recent Cleanups" Drawer

Your last 20 processed images are stored locally in your browser database. Return anytime to re-download with zero cloud tracking.

Mobile-Optimized Veo 3 Video Cleaner

Hardware-accelerated WebCodecs frame chunking processes video frames without Out-Of-Memory crashes, preserving audio tracks intact.

Social Comparison Card Generator

Render high-resolution 16:9 or 1:1 Before & After graphics with branded verification badges ready for instant sharing on social platforms.

Knowledge Base

Frequently Asked Questions

Everything you need to know about reverse alpha blending, SynthID, and offline privacy.

How does Reverse Alpha Blending remove Gemini watermarks without blur?

Traditional AI inpainting guesses and repaints missing pixels, which creates soft edges and blur. Google Gemini applies its watermark as a transparent mathematical overlay. Our tool reverses this linear compositing formula to mathematically recover the exact original background pixels underneath.

Are my images uploaded to any remote server?

What if my image was resized and leaves a faint watermark outline?

Does this tool strip invisible SynthID and C2PA AI metadata?

Can I process large batches of images at once?

How does it handle Google Veo 3 AI videos without mobile crashes?

Which formats can I export my cleaned media in?

Can I use this tool offline as a Progressive Web App (PWA)?

How does the IndexedDB Recent Cleanups drawer protect my privacy?

Is it legal to remove Gemini watermarks from my own generated artwork?
