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 do I need to extract a watermark?

Use a compatible image created with this tool and enter the exact bit length recorded during embedding.

Will the watermark survive every edit?

No. It can tolerate some compression or damage, but strong resizing, cropping, rotation, filtering, or recompression may prevent reliable extraction.

Is this cryptographic protection?

No. This is an ownership and tracking mark, not encryption or tamper-proof proof.
