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.

Can I crop for social aspect ratios?

Yes. Pick a preset aspect ratio or adjust the crop frame for square, landscape, or portrait outputs.

Will cropping add black bars?

No. The crop cuts the frame to the selected area and exports only that visible region.

Can I crop a video to square or vertical format?

Yes. Pick a preset aspect ratio or adjust the crop frame manually before exporting.

Is cropping the same as resizing?

No. Cropping cuts the visible frame area, while resizing changes the dimensions of the full frame.
