About StackConvert
A comprehensive online file converter built for privacy, performance, and ease of use. Convert files, manipulate documents, and use powerful utilities - all in your browser.
Our Mission
We believe file conversion should be fast, secure, and accessible to everyone. StackConvert prioritizes privacy by processing most files directly in your browser when possible, with minimal server interaction for specialized tasks. Your data security and convenience are our top priorities.
How It Works
Client-Side Processing: Most conversions happen entirely in your browser using WebAssembly and Canvas API. Your files never leave your device.
Maximum Privacy: No file uploads, no data storage, no tracking. Your files remain completely private.
Specialized Processing: Only certain format conversions require secure server processing, and files are immediately discarded after conversion.
