What browser encryption means
The browser creates the encrypted file package locally before it is uploaded. The service stores encrypted file data and coordinates delivery rather than treating file bodies as ordinary readable application data.
Browser encryption
Browser-encrypted file sharing explained
Browser-encrypted file sharing means the file is protected on the sender device before upload instead of relying only on transport or storage-layer encryption.
How it differs from encryption at rest
Encryption at rest protects disks, buckets, databases, and backups. Browser encryption moves the protection boundary earlier, before the application stores the file.
Why encrypting before upload matters
For sensitive documents, logs, contracts, financial files, HR packets, and client records, the key question is whether the service needs readable file contents during normal delivery.
What metadata still exists
Browser encryption does not erase operational metadata. A delivery service may still process account details, recipients, transfer size, timestamps, status, and abuse-prevention signals.
When secure links help
Secure links are useful when a recipient should not need an account, but they are lower assurance than account-bound access because the full active link can be forwarded.
Frequently asked questions
What makes ZipPigeon useful for browser-encrypted file sharing?
ZipPigeon is useful when a sensitive file needs to reach a specific person without becoming an email attachment or a standing shared-folder permission.
Can ZipPigeon read my file contents?
The normal delivery model is designed so stored file data is encrypted and raw file keys are not sent to the server. Operational metadata is still processed.
What metadata is still processed?
Operational metadata such as account information, recipient information, timestamps, file size, delivery state, and audit events may be processed.
Send the file. Keep control of the link.
Use ZipPigeon when a file needs to reach the right person without becoming another attachment or shared folder to clean up later.
