How to use the Bilibili video parser
Three steps, identical on phone and desktop.
Step 1: get the link or BV id
In the Bilibili app, open the video and choose Copy link from the share sheet; on the web, copy the address bar. The BV id (12 characters starting with BV) also works on its own.
Step 2: paste and parse
Come back here, paste into the top input, and hit Parse. b23.tv short links are followed automatically to extract the BV id.
Step 3: play or download
The video plays inline once parsed. Use the quality selector to switch renditions, Download video for the picture, Download audio for the sound track, or grab the cover.
