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.
