The visible sparkle is a known alpha blend. AiPixelClear reverses that blend within its calibrated footprint and checks the restored result before encoding your file.
How does reverse alpha blending work?
A semi-transparent white overlay mixes a known amount of white with the original colour at each marked pixel. The calibrated alpha map records those amounts. Reversing the equation recovers the underlying colour rather than generating a replacement. This operates on decoded working pixels and leaves the rest of the working image intact.
observed = α × overlay + (1 − α) × original
original = (observed − α × overlay) ÷ (1 − α)
Which profiles are calibrated?
| Profile family | Mark sizes |
|---|---|
| Images | 36 × 36, 48 × 48 and 96 × 96 px profiles |
| Video sparkle | Standard and compact landscape and portrait profiles |
| Moved complete mark | Guided template alignment through Help find the mark |
What does edge denoising do?
The FDnCNN model can reduce compression ringing around the restored footprint. It uses a small crop for context, with changes confined to the marked area in image output. The model and WASM runtime load when the denoise stage is used. They are served from the same origin as the tool.
How are exports verified?
Choose 720p or 1080p. Images are restored at source dimensions before resizing; video restoration works at the selected size. Image output is decoded again to verify its dimensions. Video checks include frame count, duration, audio presence, copied audio integrity and sampled-frame fidelity. An uncertain restoration follows the recovery path, with no cleaned download presented.
Which browser image limitations apply?
The browser image path produces 8-bit output from 16-bit PNGs and converts CMYK JPEGs to sRGB. PNG preserves transparency. WebP output uses a verified lossless encoder or falls back to PNG. JPEG uses quality 0.92 and offers a lossless PNG alternative. Identifying source metadata is stripped by re-encoding.
How do other methods compare?
| Method | What happens to pixels | Resolution | Existing exports | Processing | Cost |
|---|---|---|---|---|---|
| Reverse alpha recovery | Restores pixels using the calibrated blend | 720p or 1080p | Yes, supported sparkle exports | Your browser | Free here |
| Blur or clone stamp | Softens or copies nearby pixels | Depends on export settings | Yes, manual editing | Your editor | Depends on editor |
| AI inpainting | Generates replacement content | Depends on export settings | Yes, with a suitable editor | Depends on provider | Depends on provider |
| Source-product setting | Controls the mark on future exports | Depends on source product | Applies to future exports | Source product | Depends on plan and region |
| Upload-based remover | Depends on the selected method | Depends on service | Depends on supported inputs | Service servers | Depends on service |
What is the tool designed for?
AiPixelClear is built for the visible sparkle on supported original exports. Its method is calibrated to that overlay, with every successful output checked before download.
| Supported purpose | Scope boundary |
|---|---|
| Original Gemini-family sparkle exports | SynthID stays outside this tool’s scope. |
| Calibrated reverse alpha recovery | Other logos, text, stock marks, people and objects require a different editor. |
| 720p and 1080p exports | Resizing does not recover missing source detail. |
| Media you own or are authorised to edit | Follow the source platform’s terms and applicable rights. |
How should I prepare my file?
- Download the original from the source product.
- Keep the complete sparkle and its surrounding corner.
- Select the saved export directly from your device.
- Review the restored corner at full size before downloading.
Which engine runs here?
The engine is the open-source gemini-watermark-remover, released under the MIT licence. Its calibrated masks trace back to Allen Kuo’s GeminiWatermarkTool. Video decoding and muxing use the unmodified Mediabunny library. Read the full open-source notices.
