The Zero-Knowledge SendGB Alternative (5 GB Free + Client Encryption)
SendGB is a popular utility for sending 5 GB files without registration. However, SendGB uses server-side at-rest encryption — meaning their infrastructure holds the decryption keys. LimeShare matches the 5 GB / 500-file free limit while encrypting every byte inside your browser before upload.

Frequently asked questions
Is SendGB end-to-end encrypted?
SendGB uses TLS in transit and AES-256 at rest on cloud servers, meaning the service provider holds the keys. LimeShare generates the key in your browser and keeps it strictly in the URL fragment (#), providing mathematical zero-knowledge.
