Free Audio & Video Tools
6 browser-based media tools — trim, record, convert subtitles and plan bitrates
Media work usually means heavyweight software, but a surprising share of everyday audio and video tasks are small: cut the first ten seconds off a recording, convert a subtitle file, figure out what bitrate fits on a memory card. The tools in this category handle those jobs in the browser, no installation required.
Your media files are processed locally — trimming and conversion happen on your device, so recordings, footage and transcripts are never uploaded. That makes these tools usable even for unreleased and confidential material.
Browser media processing has quietly become powerful: the Web Audio API can decode, edit and re-encode sound, and modern JavaScript handles video containers well enough to trim without re-encoding. That's what these tools build on — which is why a laptop from a few years ago handles them fine, and why there's no server queue, credit system or upload limit involved. For color grading and multi-track editing you'll still open a real editor; for the quick cut, the format hop and the planning math, this page is faster.
