How do I convert UL to CAF using LetsConvert?

Upload your .ul file and select CAF as the target format. Choose the desired sample rate and channel count (defaults preserve the source). Click Start conversion and download the resulting .caf file. The entire process happens in your browser, so your audio never leaves your device.

Why would I convert UL to CAF instead of keeping the original?

UL files are µ-law encoded, typically 8-bit and 8 kHz, designed for telephony backbone systems. CAF (Core Audio Format) is Apple's flexible container that supports uncompressed PCM, AAC, and high-resolution metadata. Converting to CAF lets you import the audio into Apple's ecosystem (GarageBand, Logic, Final Cut) for editing and playback, without the legacy compression constraints. File sizes increase, but compatibility and editing flexibility improve.

How does the UL to CAF conversion handle audio quality and metadata?

The UL source is decoded from µ-law to linear PCM at the same effective resolution (8-bit/8 kHz). That preserves the original signal exactly while wrapping it in a CAF container. CAF supports arbitrary metadata, but the source UL format usually contains none, so the output CAF includes only basic header data. If you need higher fidelity, you’d need a better source file; conversion cannot add information that wasn't in the UL.
