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.
the privacy angle here is genuinely refreshing, and the LUFS meter alone is worth bookmarking. one thing that would make it way more useful for me would be a batch queue, basically letting me drop like 20 files at once and have the tool process them in sequence while i do other stuff
