Why FileReadyNow
Convert audio files to any format without installing software
Upload your file, choose the output format, and download the converted audio in seconds.
20 Plus Formats Supported
Convert between MP3, WAV, AAC, OGG, FLAC, M4A, and more. Pick the format your app, device, or platform actually accepts.
Bitrate and Quality Control
Choose output bitrate from 128 to 320 kbps and set the sample rate. Low for small files, high for quality-critical listening.
Batch Conversion
Upload multiple files and convert them all in one go. Each file gets its own download link so nothing gets mixed together.
Lossless Output
Convert to WAV or FLAC when you need every bit of the original audio preserved. FLAC saves around 40% of the space with no quality loss.
Files Deleted After Conversion
Uploaded and converted files are removed from the server automatically. Your audio is not stored, indexed, or shared.
No Account Required
Upload, convert, and download. No signup, no subscription, and no limit on how many files you convert.
You have a 60 MB WAV file from a recording session that needs to go to a client by email. Or you downloaded an AIFF from a project collaborator and your editing software won't open it. Or a podcast host requires MP3 but your recorder saves in M4A. This converter handles all of those in a few clicks.
Lossy vs lossless
Lossy formats (MP3, AAC, OGG, OPUS) discard audio data permanently to make files smaller. At high bitrates like 256 kbps or 320 kbps for MP3, the difference from the original is inaudible on most consumer headphones and speakers. At lower bitrates the audio gets thinner and compression artifacts appear, especially in high frequencies and quiet passages.
Lossless formats (WAV and FLAC) retain every bit of the original audio. WAV is completely uncompressed: a 3-minute song at CD quality is about 30 MB. FLAC applies lossless compression and gets that down to roughly 18 to 20 MB with no quality loss at all. Converting WAV to FLAC saves about 40% of the space with no trade-off.
The one thing that can't be undone: converting MP3 to WAV produces a large file that sounds exactly like the MP3, not like a studio recording. The data MP3 discarded is gone. You're just putting lossy audio in a lossless container. Only do this when a specific tool requires WAV input regardless of source quality.
Which format to use
MP3 is the default for anything that needs to work everywhere: email attachments, podcast uploads, phone libraries, background music on websites. 192 kbps is the practical quality floor; 320 kbps for anything people will listen to critically.
AAC (and M4A) is what Apple uses for iTunes, Apple Music, and iPhone voice memos. M4A is AAC in an Apple-specific container. AAC sounds noticeably better than MP3 at the same bitrate. 128 kbps AAC is roughly equivalent to 192 kbps MP3 in perceived quality.
FLAC is for archiving, transferring between DAWs, and audiophile libraries. No quality loss, about 40% smaller than WAV. If you're storing a collection long-term, FLAC is the right choice.
WAV is what audio editing software prefers as input. Audacity, Reaper, Pro Tools, and GarageBand all handle WAV natively without re-encoding on import. If you're exporting from a DAW, use WAV.
OGG (OGG Vorbis) is what Spotify and Steam use, generally considered slightly better than MP3 at the same bitrate. Common in web games and streaming. OPUS is the modern voice codec used by Discord, WebRTC, and WhatsApp voice. It's extremely efficient for speech at low bitrates but not necessarily better than MP3 for music.
Converting for editing vs sharing
Converting for sharing means going to MP3 or AAC. Smaller files, universal compatibility. For podcasts, 128 kbps mono MP3 is the standard. For music sharing, 256 kbps stereo AAC or MP3 covers most listeners.
Converting for editing means going to WAV or FLAC. DAWs work better with lossless source material because re-encoding artifacts don't compound during editing and mixdown. If your source is already MP3, converting to WAV doesn't restore lost quality, but it prevents additional degradation during processing.
The rule for any editing workflow: start with the highest-quality source you have, edit in WAV or FLAC, and convert to your delivery format (MP3, AAC, OGG) as the final export step. Never edit in MP3 and re-encode through multiple generations. Each round of lossy compression compounds the quality loss.

Frequently Asked Questions
Yes, the Audio Converter is free for basic usage. You can convert files without paying or signing up.
Yes, but very large files may take more time to process depending on your internet speed and system performance.
MP3 uses compression, so there may be slight quality loss. However, for most users, the difference is not noticeable.
MP3 is best for general use and smaller file size. WAV and FLAC are better for editing and high-quality audio needs.
Files are processed securely, and your uploads are not stored longer than necessary for conversion.
Yes, you can switch between formats like AAC, M4A, FLAC, WAV, and MP3 depending on your requirement.
