Utilities that actually work together.

A suite of web utilities built on one shared data model, so the result of any tool can become the input of the next. Everything that can run in your browser does.

Video Compressor

Re-encodes to a target file size or a quality preset, stepping the resolution down when the bitrate would starve it, and shows the projected size before it starts and the actual size after.

Runs entirely in your browser

Voice Changer

Shifts pitch and formants independently, so a recording reads as a different person rather than as a sped-up tape. Presets for male↔female, child, giant, helium, robot (ring modulation), telephone (300–3400 Hz band) and whisper (noise excitation). Records from the microphone or takes a file; writes WAV.

Chains, not tabs

Each of these is one run instead of four tabs and three downloads. Every tool speaks the same typed asset, so the chain is checked before it runs rather than failing halfway.
