Echora's WAV to FLAC converter makes a FLAC copy of a WAV recording, mix, or audio export. For ordinary integer PCM audio, FLAC offers a way to compress the audio without the deliberate loss of detail used by lossy formats. Check the source format and output properties before replacing a file you need to preserve exactly.
The online converter is free, requires no account or credits, and processes one file at a time. Upload from your device, start the conversion, and download the FLAC without installing software.
WAV and FLAC: What Is Being Compressed?
A WAV file commonly contains uncompressed PCM audio, but the extension can also cover other encodings or floating-point samples. FLAC losslessly compresses compatible PCM samples. Its lossless property concerns the audio supplied to the encoder, not every byte or extra field in the original WAV file.
This tool reads the WAV audio and encodes it as FLAC. The usual case is 16-bit or 24-bit integer PCM. Those samples can be preserved when the output keeps the appropriate bit depth, sample rate, and channels.
| What to compare | PCM WAV source | FLAC output |
|---|---|---|
| Audio storage | Uncompressed samples | Losslessly compressed samples |
| Precision | Source bit depth and sample type | Check against the source; do not assume every WAV is integer PCM |
| File size | Mostly determined by audio parameters and duration | Also depends on how well the signal compresses |
| Extra information | May include tags, markers, and other chunks | Complete transfer of non-audio information is not guaranteed |
When Should You Convert WAV to FLAC?
Store PCM recordings more compactly
Long recordings and mixed tracks can use substantial space as uncompressed WAV. FLAC can reduce storage while retaining suitable PCM audio samples. Before relying on the FLAC as your only copy, check playback, audio properties, and any information needed to identify the recording.
Deliver audio in a requested FLAC format
A recipient or project may ask for FLAC instead of WAV. Conversion can prepare the file format, but the delivery may also specify sample rate, bit depth, channel count, or tags. This page does not provide controls for changing those settings; check the result against the actual request.
Keep the WAV when the editing workflow needs it
Some work depends on the original WAV's floating-point samples, markers, or project information. Retain that WAV and its project files when those details matter. If an editor already accepts your WAV and space is not a concern, an additional copy may be unnecessary.
How to Convert WAV to FLAC Online
- Upload one WAV. Choose or drag in a .wav file no larger than 200MB and no longer than 30 minutes. The browser needs to read its duration before uploading.
- Start the conversion. Wait for the upload to finish and click the conversion button. FLAC is already selected, and the service uses preset encoding settings.
- Preview and download. When the task completes, listen if the browser supports the FLAC result, then download it and open it in your intended player or editor.
Each task accepts one file. For another WAV, upload it and submit a new task. Upload and processing times depend on the recording, connection, and service activity.
Check the Audio Properties and the Recording
Inspect the FLAC's bit depth, sample rate, channels, and duration. For a 24-bit PCM source, check that the output is still 24-bit when that precision matters. The page has no bit-depth, sample-rate, or compression-level selector.
Listen to the beginning, a quiet passage, a loud passage, and the ending. Also check titles, markers, or other metadata your workflow needs. Preserving audio samples and preserving the structure of the original WAV are different requirements.
A WAV file and its FLAC version normally have different file checksums because their bytes are arranged differently. If exact audio preservation must be verified, compare the decoded PCM samples in the same representation without reducing the source precision. File size, a matching filename, or a listening test alone cannot establish sample-for-sample identity.
Is WAV to FLAC Always Lossless?
FLAC can preserve compatible integer PCM audio without discarding samples. For a WAV containing ordinary 16-bit or 24-bit integer PCM, this is the intended use. It does not make a noisy or clipped recording sound better.
The source's sample type matters. The FLAC FAQ explains that FLAC does not directly store floating-point samples. A floating-point WAV may need a precision conversion before FLAC encoding, so you should not assume that a 32-bit float recording will retain every original value.
Likewise, a WAV created from previously lossy audio does not regain missing detail just because it is now stored as FLAC. Keep the original when its exact sample values, encoding, or project information must remain available.
How Much Space Will FLAC Save?
There is no fixed compression percentage. FLAC size depends on the audio content, sample rate, channels, bit depth, and encoding settings. Some recordings compress well; others save much less space. The page does not offer a target file size.
Check the source WAV before uploading, because compression happens after upload. For example, one minute of 44.1kHz, stereo, 16-bit PCM contains about 10.6MB of sample data: 44,100 samples per second × 2 channels × 2 bytes × 60 seconds ÷ 1,000,000 = 10.584MB.
At those settings, twenty minutes is about 211.7MB before file headers. It exceeds the 200MB upload limit despite being shorter than 30 minutes. These decimal-MB figures describe the uncompressed example, not a promised FLAC size. Check the actual file and any destination limit before starting a large conversion.
Frequently Asked Questions
Is the WAV to FLAC converter free?
Yes. You can convert one WAV without an account or credits, within the 200MB and 30-minute source limits.
Can I convert WAV to FLAC without losing quality?
Compatible integer PCM samples can be stored losslessly in FLAC when the appropriate audio parameters are preserved. Do not extend that to every WAV encoding or to floating-point input; keep and check the original if exact sample preservation matters.
Will a 24-bit WAV become 16-bit FLAC?
A 24-bit integer PCM WAV can remain 24-bit in FLAC; it does not have to become 16-bit. The page has no manual bit-depth setting, so inspect the output's properties before relying on that precision for your project.
Can I choose the FLAC compression level or size?
No. The page uses preset settings and offers no compression-level, bitrate, or target-size controls. The actual file size depends on the source audio and encoding.
Will WAV metadata and markers be preserved?
Complete transfer of tags, markers, and other non-audio data is not guaranteed. Check what your project needs, and retain the original WAV if those details are important.
Can I just rename .wav to .flac?
No. Renaming does not read or encode the audio. Upload the original .wav so the converter can create a real FLAC file.
What if the WAV upload or FLAC preview fails?
Check that the WAV is complete, readable, within both limits, and fully uploaded. The browser must be able to read its duration before upload. If conversion succeeds but only FLAC preview fails, download the file and try a compatible player. Re-upload the source if an earlier upload expired.
