Is the WAV to FLAC converter free?

Yes. Transcodr is free with no accounts, watermarks, or hard limits beyond your device's available memory.

Are my files uploaded to a server?

No. The conversion runs locally via ffmpeg compiled to WebAssembly, so your WAV file never leaves the browser tab.

What quality is the FLAC output?

FLAC — lossless — a lossless result, so no audio quality is lost (files are larger).

How do I convert WAV to FLAC?

Drop your WAV file above (or click Browse) — the output is already preset to FLAC — then click Convert and download the result.

Convert WAV to FLAC

Convert WAV to FLAC in seconds, free and entirely in your browser. WAV is uncompressed PCM audio — lossless, but large; FLAC is losslessly compressed audio, ideal for archiving. Transcodr runs real ffmpeg compiled to WebAssembly, so your file is processed on your own device and never uploaded.

Drop files to convert

Video, audio, images, subtitles: anything ffmpeg can read. Drop them anywhere on the page or browse from disk.

01 / Engine

Real ffmpeg, compiled to WebAssembly.

Same library Netflix, YouTube, and basically every command-line video tool relies on, running in a Web Worker. Pipe a file in, run a command, pipe bytes back out.

02 / Privacy

Nothing leaves the tab.

No uploads, no accounts, no telemetry beyond an anonymous pageview. We couldn’t see your files if we wanted to — there’s no server in the loop.

03 / Limits

It is, after all, a tab.

Files up to a few hundred megabytes convert comfortably. Beyond that, your browser starts asking pointed questions. Use the desktop ffmpeg for 4K masters.
