Client-Side Pixel Processing

AuraClear removes Gemini watermarks locally.

A lightweight Chrome extension and web sandbox for cleaning Gemini images & videos in your browser. No AuraClear uploads, no analytics, and pixel-level restoration.

Built for private image & video cleanup

AuraClear keeps the workflow short: clean images & videos from Gemini, clean a saved file, or inspect the result before exporting.

Gemini-native action

Observes compatible Gemini download actions and routes captured media through local cleaning, with the saved-file popup as a fallback.

Full-size download path

Prefers the original Gemini asset when it can resolve one, then cleans locally before saving the file.

Client-side privacy

Image and video pixels are processed locally with OffscreenCanvas. AuraClear runs no media-processing service, uploads no files to AuraClear, and collects no telemetry.

Saved-file fallback

Already downloaded an image or video? Drop it into the sandbox and AuraClear saves a cleaned copy from the same local engine.

See the Pixel-Local Restoration

Drag the slider to inspect the badge-local restoration on a calibrated image. JPEG, WebP, and video outputs are re-encoded after processing.

How the Engine Works

For supported, calibrated badge variants, AuraClear uses reverse-alpha blending to restore the decoded pixel values under the watermark.

01

Download Interception

The extension watches Gemini's page-level download path. When an image download is requested, AuraClear resolves the raw image source before saving.

02

Decoded in Memory

The image Blob is loaded locally and decoded using modern `createImageBitmap` and drawn to a headless `OffscreenCanvas`. This requires 0 extension popup permissions and runs entirely in a sandboxed thread.

03

Reverse-Alpha Blending Math

Gemini composites the watermark using:
observed = alpha * 255 + (1 - alpha) * B.
AuraClear detects the resolution tier, selects the corresponding calibrated per-pixel alpha map, aligns the badge, and solves for the original background pixel:
B = (observed - alpha * 255) / (1 - alpha).

04

Format-Aware Export

The repaired canvas buffer is saved locally. PNG output preserves the restored canvas pixels without lossy image compression; JPEG and WebP outputs are re-encoded, and video output is best-effort transcoded.
