WHY CONVERT

Why convert CAF to AIFF

01

Right-sized output for the use case

Converting from CAF to AIFF aligns the file with the encoding choices the downstream pipeline expects. The result is a deliverable that fits naturally into the destination workflow.

02

Acceptance by downstream tools

AIFF is the format most receiving systems expect for this kind of content. Converting upstream avoids the rejection and silent re-encoding that often happen when CAF reaches an unprepared pipeline.

03

Lower storage and bandwidth cost

AIFF files are typically smaller than their CAF counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.

— FAQ

Frequently asked.

Is CAF to AIFF conversion free?

Yes. LocalConvert is completely free, with no signup and no per-file or per-day limits.

Do my files get uploaded anywhere?

No. CAF to AIFF conversion happens entirely inside your browser using WebAssembly — your file never leaves your device.

What's the maximum file size?

There's no fixed cap — the practical limit is your device's available memory. Very large files may take longer or fail on low-RAM devices.

Does it work offline?

Yes — once the page has loaded, CAF to AIFF conversion works without an internet connection. Re-open the page once to cache it.

Will conversion preserve quality?

LocalConvert uses the industry-standard tools (FFmpeg, ImageMagick, Pandoc) — quality matches what professionals use on the command line. Lossy formats will still lose some quality on each re-encode.
