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.

What image formats can I use as a watermark?

Use PNG, JPG, or WebP. PNG and WebP are best when the watermark needs transparency.

Is the watermark burned into the video?

Yes. The export renders the image overlay into the MP4 frames so it appears in normal players.

Can I add a logo watermark to a video?

Yes. Upload an image watermark, position it on the video, and export a new MP4.

Can I control watermark size and placement?

Yes. Adjust the watermark on the preview before exporting so it lands where you expect.
