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.

Are my GIFs uploaded?

No. GIF decoding, enhancement and encoding run on your device. Only the model files need to be downloaded.

Will every GIF look sharper?

Results depend on the source. Anime4K is especially suited to animation and line art. Very blurry footage, small text and photographic details may not improve. Preview the result before saving.

Why are some quality levels unavailable?

Fast and Balanced require WebGL 2 with floating-point rendering. High quality requires WebGPU. Availability depends on your browser and graphics hardware. Enable hardware acceleration or try another browser if no level is available.
