Video Tools is part of DevStudio — a free, in-browser collection of developer utilities that work without sign-up, installation, or any backend service. Inspect, trim, crop, resize, compress, convert, GIF-ify, extract frames, speed-shift, join and mute video — fully in-browser, all running entirely on your device. Because the page never uploads what you paste, you can run sensitive payloads, configuration files, secrets, or production data through it with confidence: nothing leaves your browser tab. Use Video Tools for ad-hoc debugging, code review, log triage, release prep, learning a new format, or as a quick scratchpad while you build. If you use this tool a lot, pair it with PDF Studio, Image Editor, Image Converter, and the rest of the DevStudio toolkit for related developer workflows.
