Plupload is a Windows software oriented toward web developers. You can allow website visitors to upload files from their desktop or mobile devices. There is support for direct drag and drop functionality in modern browsers like Chrome. Used polyfills are completely standalone and available separately under AGPL and OEM licenses.

Main purpose

With the help of the program users can embed various file uploading features into any web application. Advanced HTML5 and XMLHttpRequest L2 APIs are utilized to facilitate data transfers.

Image upload

You are able to automatically shrink photos to generate thumbnails or avatars. Moreover, it is possible to split large pictures into several chunks and upload them simultaneously to speed up the process. Transferred parts are then safely collected on the server side and combined into the original image. This functionality is helpful for bypassing potential maximum size constraints.

Plupload provides access to raw file data, even in environments that do not normally support it. Thumbnails can be displayed instantly when the photo is selected in the dialog window or dragged and dropped from the desktop.
