Our Philosophy & Architecture

About Any File Converter

We believe converting files should not require surrendering your personal documents, medical PDFs, proprietary CAD blueprints, or family photos to remote cloud servers.

The Problem with Traditional Cloud Converters

For over two decades, online file conversion followed a flawed architecture: you upload your file to an unknown server, wait in a slow queue, and hope the server owner deletes your confidential data. Cloud converters collect your files, IP address, and metadata — creating enormous security and privacy vulnerabilities.

With the advent of high-performance WebAssembly (Wasm) and modern browser compute capabilities, this old server-side paradigm is obsolete. Your personal computer or smartphone already possesses more than enough processing power to decode, transcode, and transform complex files locally in fractions of a second.

Open-Source In-Browser Engines

Any File Converter bundles industry-standard open-source conversion kernels compiled directly to WebAssembly and executed client-side inside Web Workers:

OpenCASCADE Technology

Industrial B-Rep geometric modeling kernel compiled to WebAssembly for native STEP, STP, and IGES solid model tessellation into 3D-printable STL and OBJ meshes.

FFmpeg WebAssembly

The world standard multimedia framework running single-threaded inside your browser RAM for instantaneous MP4, MP3, WAV, WebM, and GIF transcoding.

libheif & Canvas2D

High-efficiency image container decoders that convert iPhone HEIC/HEIF photos directly into standard JPG, PNG, and WebP raster buffers.

pdf-lib & Mammoth

Pure client-side typographic parsing and generation for PDF documents, Word DOCX OpenXML packages, and structured tables.
