About
AlterSend is a free, open-source app for sending files directly between your devices — no cloud, no uploads, no size limits. Files transfer peer-to-peer and are end-to-end encrypted; nothing is ever stored on a server. Why use cloud storage when you can send files directly — instantly, privately, with no upload costs and no limits? - No accounts — no signup, no login, no email address required - No servers — files transfer directly device-to-device - End-to-end encrypted — only your devices can read your files - No file size limit — send a 100 MB photo or 500 GB video archive
