Who runs Social-X?
Why browser-side matters
Most “free online tools” upload your file to a server, process it there and hope you do not read the privacy policy. Social-X takes the opposite approach: the file never leaves your device. That is better for your privacy, it works on a plane, and it means a 40 MB scan does not have to travel twice across the internet before you get it back.
Private by design
Contracts, IDs, medical scans and client work stay on your machine. Nothing is logged, stored or resold.
Fast by default
No upload queue and no server round-trip. Your laptop’s CPU is doing the work, so results appear as soon as you click.
Works offline
Once a page is loaded, the tool keeps running even if the connection drops — useful on mobile data.
