Are my images and videos uploaded to any server?

No. All processing happens 100% locally in your browser using HTML5 Canvas and MediaRecorder APIs. Nothing is transmitted to Toologist or any third party.

How does the Dola AI watermark detection work?

The tool scans the bottom-right corner for the Dola AI logo silhouette using normalized cross-correlation and morphological top-hat filtering across multiple font scales. If confidence is high, it pinpoints the exact bounding box; otherwise, it uses calibrated fallback dimensions.

Does video watermark removal keep the original audio?

Yes! The tool extracts the audio track using Web Audio API and routes it directly into the output stream during real-time frame inpainting, preserving perfect audio-video sync.

Which file formats are supported?

Images: PNG, JPG, JPEG, WebP, AVIF, SVG, and BMP. Videos: MP4, WebM, MOV, and M4V.

Under The Hood

How Toologist's In-Browser Reconstruction Engine Works

Unlike translucent watermarks that retain original pixel values underneath, Dola AI stamps an opaque logo badge onto the bottom-right corner. To remove this mark cleanly without uploading your private media to cloud servers, Toologist combines two computer vision techniques in real-time JavaScript:

Multi-Scale Top-Hat Localization: A mathematical morphological filter extracts bright stroke silhouettes against complex backgrounds, scoring candidates with normalized cross-correlation against calibrated "Dola AI" typography.
Inverse-Distance Boundary Inpainting: Rather than blurring or smearing, surrounding edge pixels are interpolated into the bounding box with inverse-distance harmonic weighting, restoring smooth gradients and natural background continuity.
Real-Time Video Canvas Streaming: Videos are decoded frame-by-frame, inpainted at full frame rate, and re-encoded using your browser's hardware-accelerated MediaRecorder while preserving original synchronized audio.

FAQ

Frequently Asked Questions

Is my data uploaded to any server or logged?

Never. All processing runs 100% inside your browser's local sandbox memory using client-side JavaScript, Canvas, and Web Audio APIs. Your files never leave your computer or phone.

How does video processing work, and why must I keep the tab open?

Video is played through an in-memory canvas and reconstructed frame-by-frame in real-time while being recorded back into a clean MP4 or WebM video file. Browsers throttle inactive background tabs to save battery, so keeping the tab focused ensures smooth, un-throttled 60fps frame encoding.

What should I do if a slight halo or edge remains?

Use the Extra Inpainting Coverage slider above (e.g. increase from 2px to 4px–6px) and reprocess. This widens the bounding box to capture any slight compression artifacts left by image encoders.

Does this tool work on mobile devices?

Yes! Toologist runs seamlessly on modern mobile browsers including Safari on iOS, Chrome, Edge, and Samsung Internet.

Is there a file limit or subscription fee?

No. This tool is 100% free and unlimited. You can process as many images and videos as you need.
