Free Bilibili Tools
Small utilities that make working with Bilibili links easier — built by the SaveBili team. The Link Inspector and file-size calculator are live now; the rest are on the way.
Bilibili Link Inspector
Convert BV IDs to AV numbers and back, check what any Bilibili link actually is (video, b23.tv short link, bangumi, live stream…), and clean messy share text. 100% in your browser.
Video metadata viewer
See a video’s title, uploader, duration, upload date, and stats without opening the Bilibili app — handy for researchers and archivists.
Thumbnail downloader
Grab a video’s original cover image at full resolution — useful for creators making thumbnails for their own reposts and references.
File-size calculator
See how big a download will be at each quality before you start — essential on mobile data. (Per-quality sizes already shown in the main downloader.)
Subtitle downloader
Save a video’s publicly available subtitles as SRT/VTT for offline study and accessibility. Personal and educational use.
Format compatibility guide
Interactive: pick your device, get the right quality and codec to download. H.264 vs HEVC vs AV1, explained without jargon.
URL anatomy reference
The definitive English reference for reading Bilibili URLs — BV IDs, ?p= parts, b23.tv, bangumi paths — with a live converter built in.
Troubleshooting checker
Paste your link, describe the symptom, get the likely cause and fix — the interactive version of our no-sound guide.
MP3 / audio extractor
Just want the audio? A dedicated landing page for extracting MP3 from Bilibili videos you have the right to save — music, podcasts, audiobooks.
Danmaku viewer
Experimental: browse a video’s danmaku (bullet comments) as readable text. Viewer-first; scope will stay conservative.
