How do I convert a UL (u-law) file to AIFF on LetsConvert?

Upload your UL file, select AIFF from the dropdown, choose an optional sample rate and bit depth (e.g., 44.1 kHz/16-bit), and click Convert. Your AIFF will be ready for download immediately. LetsConvert supports batch conversion for multiple UL files.

Why should I convert UL to AIFF instead of using the original UL file?

UL (u-law) is a compressed telephony format commonly used in VoIP and legacy systems. AIFF is an uncompressed, lossless audio format that preserves complete fidelity and is natively supported by Apple’s QuickTime, Logic Pro, and iTunes. Converting to AIFF makes audio editable and playable on professional audio workstations without codec artifacts, at the cost of larger file size.

How does LetsConvert handle sample rate, bit depth, and channels when converting UL to AIFF?

LetsConvert decodes the UL stream and re-encodes it as PCM 16-bit AIFF, preserving the original sample rate (typically 8 kHz) and channel configuration. If you choose a higher sample rate, we apply high-quality resampling. Bit depth is upsampled from 8-bit μ-law to 16-bit linear PCM, which eliminates the μ-law encoding curve and provides a clean, linear representation of the waveform.

Yes, UL-TO-AIFF on LetsConvert is 100% free with no registration or hidden fees required.
