Convert raw audio files (PCM) online for free
The converter easily converts your PCM audio files to various formats - free and online. No Audacity or or other Audio software needed.
The converter also works in reverse, so you can convert other "Uncompressed Audio Format" formats to PCM without using software like Audacity or a similar tool.
The .PCM file extension is most heavily utilized for Pulse Code Modulation audio. This format stores raw, uncompressed digital audio data by capturing analog sound waves as discrete mathematical samples at regular intervals. You will typically encounter these files in professional audio engineering, legacy video game systems (like SNES MSU-1 audio), telecommunications (such as Skype's SILK codec), and synthesizer sound sample banks from manufacturers like Korg. Less commonly, .PCM files store vector instructions for CNC plasma cutting machines via PlasmaCAM software, or act as precompiled C++ modules for developers.
Working with raw .PCM audio files is incredibly frustrating. Unlike standard audio formats, a raw .PCM file completely lacks a metadata header. It does not contain basic playback instructions like sample rate, bit depth, or channel count. If you try to open it in a standard media player like VLC or Windows Media Player, the software will fail or blast distorted static noise. You are forced to import the file as "Raw Data" into professional tools like Audacity and manually guess the correct playback parameters. Furthermore, because the audio is uncompressed, file sizes are massive, making them impossible to share over email or embed on web pages.
To make these files functional, you must convert them. For universal playback and lossless archiving with a proper metadata header, convert .PCM to WAV or FLAC. For web delivery or casual listening, convert to a compressed MP3 or AAC. If you are dealing with a PlasmaCAM CNC file, converting to an industry-standard DXF is necessary for cross-compatibility. Drag and drop your file here to analyze and convert it securely right in your browser - free, online, and without installing complex audio engineering software.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PCM converter.
