About DeviceLab

DeviceLab is a collection of 26 free, browser-based diagnostic and utility tools for your phone and computer. Every tool runs locally inside your browser — no installs, no signups, no files uploaded. We built it to help you test and fix common device problems (speakers, mics, cameras, screens) and handle everyday conversions and file tasks, all in one place.

If a tool asks for camera, microphone, or location permission, it uses that capability only for the tool you are running and never stores or transmits your data.
