TrueRes.io — Free Browser
Free browser-based audio & video tools — no uploads ever
69 pro-grade audio & video tools that run 100% in your browser. Analyze hi-res audio, measure LUFS loudness, view spectrograms, convert formats, trim video — all client-side. Your files never leave your device. No signup, no watermarks, no limits.
I built TrueRes because every "free" audio tool online either uploads your files to a server, slaps a watermark, or caps you at 2 minutes. As an audio engineer, that drove me nuts.
TrueRes runs entirely in your browser using Web Audio API and WebAssembly (ffmpeg.wasm). Nothing is uploaded. Ever. The DSP is real — proper K-weighted LUFS to BS.1770-4, Cooley-Tukey FFT spectrograms, lossy transcode detection, bit-depth forensics.
69 tools across 7 categories: audio analysis, loudness measurement, format conversion, video processing, signal generators, reference utilities, and audiophile testing.
Some highlights:
→ Hi-Res Verifier — detects fake hi-res (upsampled content)
→ LUFS Meter — checks compliance against Spotify, Apple, YouTube targets
→ Batch Album Analyzer — DR scores for entire albums in one table
→ Audio/Video Converter — FLAC, MP3, WAV, MP4, WebM, GIF
→ Vocal Remover — center-channel cancellation, no AI needed
Everything is free. No accounts, no paywalls, no ads (yet). Built with React, TypeScript, Zustand, and Web Workers for non-blocking analysis.
Would love your feedback — especially on which tools to prioritize next.
