How is this different from the converter sites?

All of them queue your file behind everyone else's job and run banner ads. Morph runs the encoders via WebAssembly directly in your browser — no upload, no queue, no caps, no ad walls.

Yes. Drop a folder, drop fifty files, drop two hundred. The free tier has no batch limit. The only constraint is your device's available memory.

What about file size limits?

Morph is bounded only by your device's memory. The converter sites cap free uploads at 10 MB, or 1 GB free and 5 GB paid. Morph laptops handle multi-gigabyte concert recordings without breathing hard, because the file never moves.

Audio Converter — Audio In. Audio Out. Any Format.

Q: Which audio formats does Morph support?

Every direction between MP3, WAV, FLAC, AAC, M4A (AAC and ALAC), ALAC, OGG Vorbis, OPUS, AIFF, WMA, and AC3. The encoders are LAME (MP3), FFmpeg (everything else), libvorbis (OGG), libopus (OPUS), and FLAC's reference encoder — all compiled to WebAssembly and bundled into the browser tab. No 'premium-only' formats. Every conversion is free.

Q: Are tags and metadata preserved?

Yes. ID3v2 tags (MP3), Vorbis comments (FLAC, OGG, OPUS), MP4 metadata atoms (M4A, ALAC, AAC), and BWF/RIFF chunks (WAV, AIFF) are read from the source and written to the output where the format supports it. Cover art carries over. ReplayGain tags carry over. Track numbers, album titles, artist names — all preserved.

Q: Does it work on iPhone or iPad?

Yes — Safari on iOS supports WebAssembly fully. Drop any audio file from Files or iCloud Drive, pick the output, save back. The conversion runs locally on your iPhone, never touches a server.

What it actually does

01

UNIVERSAL

11 formats. Every direction. Studio-grade encoders bundled in.

LAME for MP3 — the same encoder professional studios use. FFmpeg for everything else. libvorbis (OGG), libopus (OPUS), FLAC reference encoder. All compiled to WebAssembly and running in your browser tab. No "premium-only" formats. Every conversion is free.

02

BATCH

Drop a folder

50 files, 200 files, an entire album. No batch limit. Constraint is your device's RAM, not a quota.

03

METADATA

Tags preserved

ID3v2, Vorbis comments, MP4 atoms, cover art, ReplayGain — all carry over.

04

PRIVATE

No server

Your files never leave your tab. Nothing logged. Nothing queued.

How it works

Open morph.cool.
Drop any audio file: MP3, WAV, FLAC, AAC, M4A, ALAC, OGG, OPUS, AIFF, WMA.
Pick output format. Every direction supported. Bitrate, sample rate, channels in the same panel.
Convert. The encoders run in WebAssembly in your tab.
Download. The new file lands on your machine. Source is untouched. Nothing was uploaded.

Why "audio converter" sites all feel the same

Because the business model is the same. Upload your file. Wait in a queue. View ads. Hit a quota. The encoders are commodity — LAME, FFmpeg, libvorbis — but the queue, the cap, and the upload requirement are how those sites stay in business. Flowcut bundles the same encoders into a browser tab. No queue (no server). No cap (no upload to cap). No ad inventory (no need). Universal conversion lives where it should: on your machine, in your tab, free.
