Frequently Asked Questions
What is the fundamental difference between SwissTransfer and Filarr?
SwissTransfer (by Infomaniak) is a great Swiss service with strong ethics, but relies on encryption at rest where Infomaniak holds the keys. Filarr Send provides true client-side end-to-end encryption (E2EE): files are encrypted on your machine before upload, and the key travels in the URL fragment (#) which servers never receive.
Why is Swiss hosting alone not always enough?
Swiss law is robust, but still relies on legal trust. If compelled by a court order, a host holding the keys must provide the files. With Filarr, protection is cryptographic: we cannot decrypt your files even if legally compelled.
How much does Filarr Send cost?
Filarr Send is 100% free for transfers up to 2 GB with no account. For daily workflows, you can download the Filarr desktop app.
