Why Free Tech Lab?
Most “free” converters upload your files to their servers. Free Tech Lab doesn't. Every tool runs inside your browser using modern web technology (WebAssembly, Canvas, pdf-lib), so your photos, contracts and videos never leave your device. It's faster too, with no upload or download queue.
