The Alee Privacy & Security Advantage

Why In-Browser Processing is Safer Than Cloud Uploads

Traditional online utilities force you to upload your personal photographs, sensitive corporate documents, contracts, and code to remote servers. This introduces real security risks: your files can be intercepted over the network, stored on third-party cloud disks, or retained indefinitely.

Alee Tools works completely differently: every calculation, conversion, resizing, and encryption operation in Converter JPG para PNG is performed 100% locally in your device's browser memory via modern WebAssembly and HTML5 Canvas APIs. Zero bytes are uploaded to our servers, zero telemetry logs your file content, and your data remains strictly confidential and secure.
