What Is Audio Conversion?
Audio conversion is the process of transforming a sound file from one format to another. Different devices, platforms, and applications require different audio formats — your car stereo might only play MP3, your DAW might need WAV, and a podcast host might require AAC. Our online audio converter bridges these gaps by letting you switch formats instantly on your device.
The tool decodes your input file and re-encodes it in the format you choose. For MP3 output, it uses a fast encoder optimized for quality. For WAV, it writes raw 16-bit PCM data — lossless and universally compatible.
Unlike desktop audio converters that require downloading and installing software (often with trial limitations or paid licenses), our online converter works on any device with any modern device. There is nothing to install, no account to create, and your audio files are never uploaded to any server.
Whether you need to shrink a podcast recording, prepare music for an old MP3 player, convert FLAC to WAV for editing, or simply change the format of a voice memo, this tool handles it in seconds with a clean, intuitive interface and real-time progress feedback.

A powerful, private, and completely free audio conversion experience
Wide Format Support
Import audio in MP3, WAV, OGG, AAC, FLAC, M4A, WEBM, OPUS, AIFF, and WMA. The tool supports a wide range of audio codecs, so most common audio formats can be converted.
Adjustable Bitrate
Choose from 64, 128, 192, 256, or 320 kbps when converting to MP3. Lower bitrates produce smaller files; higher bitrates preserve more audio detail. Pick the sweet spot for your use case.
100% Private Processing
Your audio file is decoded and re-encoded entirely on your device. Nothing is uploaded to any server. Close the tab and everything disappears.
Lossless WAV Output
When you convert to WAV, the tool produces an uncompressed 16-bit PCM file at the original sample rate. This is ideal for audio editing, mastering, or archiving where quality loss is unacceptable.
Fast Conversion
The MP3 encoder processes audio in small blocks and reports real-time progress. A typical 5-minute song converts in just a few seconds on modern hardware.
Works on Any Device
No software to install. The converter runs in Chrome, Firefox, Safari, and Edge on desktop, tablet, and mobile. Just open the page, drop your file, and convert.

User Questions & Reviews
Real questions from users and expert answers from the OnlinePCTools team
“I have a bunch of WAV recordings from my podcast and need to convert them to MP3 for publishing. Will this tool handle hour-long files?”
Alex Rivera
Podcast Host, Los Angeles, USA
Yes. The tool can process long audio files — it decodes the entire file, then encodes it block-by-block with real-time progress reporting. An hour-long WAV may take 30–90 seconds to convert to MP3, depending on your device. Just keep the tab open while it processes.

“I need to convert OGG files to MP3 for my car stereo. Will the quality be decent at 192 kbps?”
Priya Nair
Music Enthusiast, Chennai, India
Absolutely. 192 kbps MP3 is considered high quality and is virtually indistinguishable from the original for most listeners. For critical listening, you can go up to 320 kbps. The OGG file will first be decoded to raw audio, then re-encoded as MP3, so you get a clean conversion.

“Is my audio data safe? I’m converting confidential voice memos from a legal deposition.”
James Park
Legal Consultant, London, UK
Completely safe. The entire conversion runs on your device — your audio file and the converted output never leave your device. There is no server-side processing, no upload, no storage, and no analytics that touch your content. Once you close the tab, nothing remains.

“Can I convert a FLAC file to WAV? I need an uncompressed version for my DAW.”
Sarah Kim
Audio Engineer, Seoul, South Korea
Yes. The tool will decode the FLAC to raw PCM audio, then encode it as a 16-bit WAV file at the original sample rate. The result is a lossless, uncompressed WAV ready for your DAW.
