MORPH Media Converter — Help & Documentation

MORPH is a universal media converter using FFmpeg compiled to WebAssembly. It converts audio, video, and image files entirely in your browser — no server uploads, no data transmission.

1. Select a tab: Audio, Video, or Image 2. Upload a file using the drop zone 3. Select an output format by clicking a format button 4. Adjust quality/bitrate if available 5. Click Convert 6. Download the result

Supported formats: MP3, WAV, OGG, FLAC, AAC, M4A, OPUS, AIFF, WMA, AMR. Adjust bitrate for quality/size control. Higher bitrate = better quality.

Supported formats: MP4, WebM, MKV, AVI, MOV, FLV. Video conversion is CPU-intensive — large files take time. The browser may appear slow during conversion.

Convert between image formats with optional quality and resize controls.

MORPH uses FFmpeg compiled to WebAssembly. On first use, it downloads core files (~30MB) which are cached. The engine supports the same codecs as desktop FFmpeg but runs in your browser sandbox.

• MP3 to WAV is fast (decompression only)
• WAV to MP3/OGG compresses the file significantly
• For video, MP4 with H.264 has the widest compatibility
• WebM is best for web use (smaller than MP4)
• Keep videos under 100MB for best browser performance

First conversion slow: FFmpeg WASM files need to download (~30MB). Cached after first use.
Conversion fails: Check console for CORS or Worker errors. Some browsers restrict Web Workers.
Browser freezes: Large video files are CPU-intensive. Try smaller files or lower resolution.
Format not available: Some codec combinations may not be supported in the WASM build.
