Are files uploaded for this tool?

This browser tool processes the selected media locally on this device. The file is not uploaded to ArtPlayer servers for this workflow.

Will the export have a watermark?

No. ArtPlayer browser tools do not add watermarks to exported files.

Why can processing take time?

The work runs in your browser, so speed depends on your device, browser, memory, source size, and the export settings needed for the result.

Which browsers work best?

Recent Chrome, Edge, and other modern Chromium browsers usually work best for heavier browser media processing.

What should I try if a large file fails?

Try a smaller source, close other heavy tabs, reduce resolution or duration first, and keep the tab open until the export finishes.

How does automatic face pixelation work?

The page detects faces in video frames with MediaPipe, expands each box slightly, and burns mosaic pixelation into the exported MP4.

Can I use it for privacy edits?

Yes. It is designed for quick local face privacy edits, but review the result before sharing because detection can miss faces in motion or side profiles.

Can I pixelate faces instead of blurring them?

Yes. Pixelation gives a stronger blocky privacy effect than soft blur.

Do I need to check the result manually?

Yes. Review the export to confirm the face coverage is good enough before publishing.

How it works

Three steps to finish the browser workflow.

1
Choose a video file
Automatically detect faces in a video, cover them with mosaic pixelation, and export a local MP4 without uploading.
2
Face detection
Choose a video, then ArtPlayer will scan the preview frame for faces.
3
Pixelate faces
Choose a video, set the mosaic size, then ArtPlayer detects faces with MediaPipe and renders the pixelated result locally.

Everything you need

Core details about privacy, browser support, output, and practical limits before you start.

Automatic face detection

MediaPipe scans video frames and tracks visible face boxes for quick privacy edits.

Mosaic privacy effect

Detected faces are expanded and pixelated frame by frame before the MP4 is encoded.

Local workflow

The video is processed in your browser with MediaPipe, Mediabunny, WebCodecs, and canvas rendering.

Input, output and limits

Check supported inputs, output formats and usage requirements before you start.

Supported input	Video files such as MP4, MOV and WebM. Container and codec support depends on the browser and processing runtime.
Output result	Export options: MP4.
Processing and privacy	Processing runs on this device. Source media is not uploaded for this workflow.
Browser requirements	A browser with the decoding and encoding capabilities needed by the selected media. Available codecs vary by device.
Usage limits	Processing capacity depends on duration, dimensions, codecs, settings and available device memory. Large inputs can fail; keep the original file.
Can I use it for privacy edits?	Yes. It is designed for quick local face privacy edits, but review the result before sharing because detection can miss faces in motion or side profiles.
