Mathematical Privacy. Zero Uploads.
Most document tools promise they delete your files after 1 hour. We promise we never see your files in the first place.
The WebAssembly Revolution
Document Sanitization Standards & Cryptographic Rigor
Engineered against published academic vulnerability models and national media sanitization guidelines.
Permanent Vector Sanitization
Prevents the critical vulnerability where masked text retains underlying glyph coordinates, by permanently excising binary content and burning raster pixels.
PoPETs 2022 Privacy Research (Chen et al., Privacy Enhancing Technologies Symposium)
NSA & NIST SP 800-88 Sanitization
Adheres to national intelligence guidelines for irreversible sanitization, purging embedded object trees, hidden revision histories, and structural metadata.
National Security Agency (SNAC Guidance) & NIST Guidelines for Media Sanitization
In-Memory Sandboxed Isolation
Document buffers reside strictly in ephemeral WebAssembly linear memory, inaccessible to cross-origin scripts and automatically garbage-collected upon tab closure.
W3C WebAssembly Core Specification & RFC 1951
Your Documents Are Blind To Us
While we use standard analytics to improve our website experience, our scripts never touch your documents. We do not extract metadata, text contents, or images. The document processing sandbox is entirely self-contained within your browser tab.
Compliance by Default
Because HandleMyFile cannot access your files, using our tools automatically complies with the strictest data protection laws worldwide.
Don't Trust Us. Verify It.
You don't have to take our word for it. You can prove our offline guarantee yourself in 3 simple steps:
The Future is Local
We envision a web where utility apps respect your hardware and your privacy. Welcome to the new era of client-side computing.
