Bilibili thumbnail downloader
Grab the cover image from any Bilibili video in full resolution. Paste a link, pick a size.
What this does
A Bilibili thumbnail downloader saves the cover image of a video as a JPG or WebP file. Paste the video URL, and the tool reads the cover image address from Bilibili's public metadata and offers it at several resolutions — original, 1920 pixels, 1280 pixels and 640 pixels wide.
Which size should you pick?
| Option | Typical size | Use for |
|---|---|---|
| Original | 1146 × 717 px | Anything where quality matters — this is the real uploaded file |
| 1920 × 1080 | ~250 KB JPG | Presentation slides, video editing backgrounds |
| 1280 × 720 | ~120 KB JPG | Blog posts, documents |
| 640 × 400 | ~40 KB JPG | Reference, previews, chat sharing |
Note that 1920 is a CDN upscale when the original is smaller. Original is always the highest genuine detail.
Questions
How do I download a Bilibili thumbnail?
Paste the video link into the box on this page and press Get thumbnail. You will see the cover image with download buttons for each available size, from the original upload down to a 640 pixel version.
What resolution are Bilibili thumbnails?
Bilibili stores cover images at whatever resolution the uploader supplied, commonly 1146 by 717 pixels. Its image CDN can then resize on request, which is how this page offers 1920, 1280 and 640 pixel versions of the same picture.
Can I download a thumbnail in HD or 4K?
You can request up to 1920 pixels wide. Anything larger than the original upload is an upscale rather than genuine extra detail, so the Original option is always the highest real quality available.
Is it legal to use a Bilibili thumbnail?
The cover image is copyrighted by whoever created it, usually the uploader. Downloading one for personal reference is low risk, but republishing it, using it as your own thumbnail, or putting it in commercial material needs permission from the rights holder.
Why is the thumbnail a WebP file?
Bilibili serves WebP by default because the files are smaller. This page offers JPG versions too, which are more widely compatible with older editing software.
