AuraClear removes Gemini watermarks locally.
A lightweight Chrome extension and web sandbox for cleaning Gemini images in your browser. No server uploads, no analytics, and pixel-level restoration.
Built for private image cleanup
AuraClear keeps the workflow short: clean from Gemini, clean a saved file, or inspect the result before exporting.
Gemini-native action
Adds a small AuraClear button next to Gemini's own download control, then routes hard cases through the native download hook.
Full-size download path
Prefers the original Gemini asset when it can resolve one, then cleans locally before saving the file.
Client-side privacy
All image processing executes locally within your browser context using OffscreenCanvas. No external API calls, no image uploads, no logs.
Saved-file fallback
Already downloaded an image? Drop it into the sandbox and AuraClear saves a cleaned copy from the same local engine.
See the Lossless Quality
Drag the slider to inspect the exact pixel restoration. AuraClear removes the badge cleanly without any blur or degradation.
How the Engine Works
AuraClear executes reverse-alpha blending math to restore the original pixel values under the watermark.
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.
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.
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).
Lossless Export
The repaired canvas buffer is re-encoded into a same-format blob and saved to the local disk via a synthetic download trigger. The user receives a pristine, watermark-free file without any compression artifacts.
