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.

Which cover image formats can I use?

Use JPG, PNG, or WebP artwork. Square cover art usually looks best in music players.

Does adding cover art upload my audio?

No. The audio and image are read and rewritten locally in your browser with Mediabunny.

Will this edit my original audio file?

No. The original stays unchanged, and the page creates a new M4A export with the cover image attached.

Why is the export M4A?

The first browser workflow writes a conservative MP4/M4A-style output so artwork metadata can be embedded reliably where supported.
