LibSpace Boox Connector by LibSpace

LibSpace Boox Connector sends files from your browser directly to your Onyx Boox e-reader using the Boox cloud sync API.

The whole flow takes about 2 seconds: drag a file, it's on your device. No USB cable, no waiting for BooxDrop to find your local network, no clunky email-to-device dance.

WHAT YOU CAN SEND
Boox supports 20+ file formats out of the box: EPUB, PDF (up to 2GB), MOBI, AZW3, FB2, DJVU, DOC, DOCX, PPT, RTF, TXT, HTML, CHM, comic archives (CBR/CBZ), and image files (PNG, JPG, BMP, TIFF).

REGIONS SUPPORTED
United States (push.boox.com), Europe (eur.boox.com), and China (send2boox.com).

PRIVACY
The extension talks directly to Onyx's Boox API. Your files never touch our servers — we don't run any. We don't have user accounts. Your Boox session token is stored locally in your browser. We collect
anonymous usage events (sends, errors) but never the file contents or names.

HOW IT WORKS
1. Sign in with your Boox account email
2. Onyx emails you a 6-digit verification code
3. Drag any file into the popup — it appears on your Boox in seconds
