Follow the data behind DWYT format evidence
DWYT needs the submitted public URL and returned media facts to show video, audio, image, subtitle, and document choices accurately. Job identifiers, coarse performance data, byte counts, and protected visitor signals support delivery and reliability. Temporary files expire. Browser-side preferences and local-media work stay on your device as described below. This local page is different: the selected file is read with the browser File API and written into temporary WebAssembly memory, with no media-upload endpoint.
