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.

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

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

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

You can export video as MP4 or WebM, or save only the audio as MP3.

Yes. Choose the MP3 output when you only need an audio file from the video.

Yes. Choose MP4 as the output format when you need a broadly compatible video file.

Yes. Choose MP3 when you want to extract the soundtrack into an audio-only file.

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

The selected video is processed in this browser through the shared FFmpeg task page.

Export MP4 for compatibility, WebM for the web, or MP3 for audio.

The MP3 option turns a video into a standalone audio file without uploading it.

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 / WebM / MP3.
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 extract audio while converting?	Yes. Choose the MP3 output when you only need an audio file from the video.
