MP4 video up to the highest resolution the source provides (commonly 1080p), MP3 audio up to 320 kbps, and thumbnail images in every size that is published for the video.
No. Nothing is uploaded to or stored on our servers. Each file is retrieved and processed only when you request it, streamed straight to your device, and never retained. See our Privacy Policy.
High-definition video and audio are delivered as separate streams that we combine while your download runs, which adds a few seconds. Some videos may also be private, age-restricted, region-locked, or otherwise unavailable, in which case they cannot be processed.
