Multipart uploads to Amazon S3 made easy!

S3Uploader is a hosted service that makes it super easy to upload very large files to an Amazon S3 bucket using just a web browser.

Rolling your own multipart uploader or using an open source script might seem tempting but will require expert knowledge and constant updates, we remove that headache thus lowering development costs. Our service works by embedding an uploader directly into your site, all the necessary backend functionality is handled by our server. Paste some simple code into your site or app and be up and running in minutes!

"I rarely give testimonials but with S3Uploader I am happy to take an exception. As a longtime user of S3Uploader we’ve come to trust the service completely. Our Eurovision Showcase content marketplace frequently receives very large video uploads and S3Uploader has handled them with ease. There have been no major issues, and the few integration problems we’ve had have been dealt with very quickly and efficiently by their support team. A five-star product and support service."
