A few months ago I started learning traditional Chinese painting from a series of tutorials on Bilibili. The videos were detailed and the teacher explained brush techniques slowly. But my internet connection at home cuts out during storms. I missed a key segment about mixing ochre. So I decided to download the whole playlist for offline viewing. That sounds simple, but Bilibili doesn’t offer a built-in download button for most content. I tried browser extensions and screen recorders. The quality dropped. The subtitles got lost. The file names were a mess. I needed something that kept the metadata intact and let me organize by artist name and date. That is when I found the bilitools official site. It lets me grab videos in the original resolution, preserve the comment section for later reference, and batch download whole series. I use it every week now.

Why would anyone bother with offline archives? Streaming works fine for casual watching. But for reference material — tutorials, lectures, museum walkthroughs — a local copy saves time and frustration. I have a folder on an external drive labeled “2024 painting references.” Inside are folders for each course. Each video file is named with the uploader, title, and date. If the original uploader deletes their channel or a video gets region-locked, I still have it. Archiving is a hobby, not a chore. It feels good to keep a personal library of content that matters to you.

Choosing the right tool for the job

Not all download tools handle Bilibili well. Some need constant updates because the site changes its player. Others strip the audio or convert everything to a single format. I tested three before settling on Bilitools. The first one only worked for mobile links. The second lost the CC subtitles that come with many educational videos. The third had a confusing interface with options I didn’t understand. Bilitools kept things simple: paste the link, pick the resolution, click start. I can choose between MP4 and MKV containers. The MKV option keeps the subtitles embedded as separate streams, which is useful when I want to toggle them off. The download speed matches my connection, and I have not hit any daily limits. For a hobbyist collector, that reliability matters more than flashy features.

How I organize my offline collection

After downloading, I sort the files into a consistent structure. Here is the system that works for me:

• Create a main folder per year, then subfolders by topic (e.g., “Chinese painting” or “urban sketching”).
• Rename each video to include the uploader’s username, the video title, and the length in minutes so I can quickly estimate time commitment.
• Add a plain text file with the original Bilibili URL and a note about why I saved it (e.g., “good demo of pine tree branches”).
• For series, I maintain a master index spreadsheet with episode numbers, titles, and any annotations about specific timestamps.
• Back up the entire collection to a second drive once a month using free sync software.

That may sound obsessive. But having a dozen painting tutorials ready on a quiet Saturday morning without hunting for WiFi is worth the setup. I also share specific files with a friend who teaches art at a community center. She uses them in her classroom projector. Bilibili blocks some content outside China, so an offline version is the only way she can show the original lecture. The tool handles playlists, so I can send her the whole set in one download. She appreciates not having to wrestle with proxies.
