Resumable.js is a JavaScript library providing multiple simultaneous, stable and resumable uploads via the HTML5 File API. The library is designed to introduce fault-tolerance into the upload of large files through HTTP. This is done by splitting each files into small chunks; whenever the upload of a chunk fails, uploading is retried until the procedure completes.

Resumable.js allows uploads to automatically resume uploading after a network connection is lost either locally or to the server. Additionally, it allows for users to pause and resume uploads without loosing state. Currently, it is limited to Firefox 4+ and Chrome 11+.
