How it works

Simple.
Direct. Yours.

01 — UPLOAD
Only you know what's inside
Drag up to 5 GB of files. Our system processes them and shows you the real saving before you pay a single cent.
02 — SECURE
A file no one else can open
The resulting .sybackup works exclusively with Syfile. It's yours and only yours. Pay once and download it — no recurring charges ever.
03 — FOREVER
Reconstruct in a year, in five, whenever
Come back any time with your .sybackup and we restore every original file exactly as it was. No expiry. Completely free.
💡
Tip for maximum savings: The optimization engine performs much better when processing duplicate or similar files, achieving higher efficiency without deleting or altering any of your files.
