How to Convert WAV to WAV Online
- Upload Your WAV Files: Drag and drop or click "+ Add Files" to load
.wavfiles from your computer. Batch upload is supported — normalize an entire folder of mismatched session files in one pass. Files stay on our servers and uploaded only to xconvert's own servers, auto-deleted after a few hours. - Set Audio Sample Rate: Default is Original (leave the source rate intact). Pick 48000 Hz to match video / broadcast deliverables, 44100 Hz for CD-standard music, 24000 Hz or 22050 Hz to roughly halve file size for voice, or 16000 Hz / 8000 Hz for telephony-grade speech.
- Set Audio Channel and Trim (Optional): Switch Audio Channel from Original to Mono to halve the size of a stereo voice recording, or keep Stereo for music. Use Trim with a start time and duration (seconds, or
HH:MM:SS.sss) to cut intros, silence, or dead air at the end of a take. - Convert and Download: Click "Convert" and your re-saved WAV downloads in seconds. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.
Why Convert WAV to WAV?
WAV (Waveform Audio File Format) is the lossless PCM audio container published by Microsoft and IBM in 1991. It's the default capture format for Windows recording apps, most DAWs, broadcast workflows, and CD authoring. "Converting WAV to WAV" sounds redundant, but it's how you re-save a WAV with a different sample rate, channel layout, or trimmed length — without leaving the .wav extension that DAWs, samplers, and CD-burners require. Typical reasons to re-encode WAV:
- Match a DAW's session rate — Pro Tools, Logic, Ableton, and Reaper all complain when an imported file's sample rate differs from the project. Re-saving a 48 kHz field recording to 44.1 kHz (or vice versa) avoids on-the-fly resampling and the subtle pitch/timing drift that comes with it.
- Prep audio for CD burning — Red Book audio CDs require 16-bit, 44.1 kHz, stereo PCM. A 24-bit / 48 kHz studio bounce must be downsampled and dithered before it will burn to a Red Book disc. Re-saving as 44.1 kHz WAV is step one.
- Shrink voice files by half — Stereo recordings of a single speaker waste a channel. Switching from stereo to mono halves the file size with zero perceptual loss for voice, lectures, or dictation. Combined with a 22.05 kHz sample rate, a 1-hour interview drops from ~635 MB to ~80 MB while staying lossless WAV.
- Fit WAV inside the 4 GB limit — Standard WAV uses a 32-bit unsigned integer for chunk size, capping a single file at ~4 GiB (roughly 6.8 hours of 16-bit / 44.1 kHz stereo, per the RIFF spec). Lowering sample rate or switching to mono buys you headroom for long captures before you need RF64.
- Trim long captures — Field recordings, board mixes, and long-form interviews often have 30+ minutes of dead air at the head and tail. Trimming with start time + duration writes a clean WAV with just the segment you want — no re-encoding artefacts since PCM is lossless.
- Standardize a sample library — Drum hits and instrument samples bought from multiple vendors arrive at mismatched rates (48 kHz, 44.1 kHz, 96 kHz). Re-saving the lot to one rate keeps the sampler from resampling on every trigger.
Need to leave WAV entirely? WAV to MP3 for shareable lossy audio, WAV to FLAC for lossless at roughly half the size, or WAV to M4A for Apple-friendly AAC. To shrink while staying in WAV, see the dedicated WAV Compressor.
WAV Sample Rate Cheat Sheet
Numbers below assume 16-bit stereo PCM unless noted. Size per hour is the resulting file at that rate.
| Sample rate | Bitrate | Size per hour (16-bit stereo) | Best for | Notes |
|---|---|---|---|---|
| 96000 Hz | 3072 kbps | ~1.32 GB | High-resolution mastering source | Overkill for distribution; pro studios only |
| 48000 Hz | 1536 kbps | ~660 MB | Video / broadcast deliverables | Standard for film, TV, YouTube, podcasts that sync to video |
| 44100 Hz | 1411 kbps | ~635 MB | CD audio, general music | Red Book CD standard; default for music releases |
| 32000 Hz | 1024 kbps | ~460 MB | FM broadcast archival | Older NICAM and digital radio captures |
| 24000 Hz | 768 kbps | ~345 MB | Voice with light music | Speech intelligible, music acceptable on phone speakers |
| 22050 Hz | 706 kbps | ~318 MB | Voice-only podcasts, lectures | Half of CD rate; common for spoken-word archives |
| 16000 Hz | 512 kbps | ~230 MB | Telephony / VoIP source material | Matches G.722 wideband telephony |
| 8000 Hz | 256 kbps | ~115 MB | Voicemail-grade speech | Telephone narrowband; do not use for music |
File-size math: bytes ≈ sample rate × (bit depth ÷ 8) × channels × seconds, plus a small RIFF header.
Stereo vs Mono — When to Drop a Channel
| Property | Stereo | Mono |
|---|---|---|
| File size | Baseline | Exactly half |
| Best for | Music, ambient, stereo interviews | Single-speaker voice, AM-radio-style audio, dictation |
| Reversible? | Mono → stereo only duplicates the channel; you can't recover spatial info | Stereo → mono is destructive if the two channels carried different signal |
| Speech intelligibility | Identical | Identical |
| Storage savings | 0% | 50% |
| Compatibility | Plays everywhere | Plays everywhere; some music apps auto-pan to center |
For lecture recordings, audiobooks, voice memos, and Zoom captures the mono switch alone saves more space than any other lossless change.
Frequently Asked Questions
Why would I convert a WAV file to another WAV file?
To change something inside the file without changing the extension. You might be downsampling 48 kHz to 44.1 kHz for a CD burn, switching a stereo voice memo to mono to halve its size, trimming dead air, or re-saving a recording with a clean header after recovery software produced a malformed RIFF. The output is still uncompressed PCM WAV — every DAW, sampler, and Red Book CD authoring tool will accept it.
Will converting WAV to WAV reduce quality?
Not inherently — WAV stores uncompressed PCM, so re-saving at the same sample rate, bit depth, and channel layout is bit-identical to the source. Quality only changes if you change a parameter: downsampling from 48 kHz to 22.05 kHz removes audio content above ~10 kHz, and folding stereo to mono loses spatial information. Trimming is lossless. Keeping the default Original sample rate and channel passes the PCM data straight through.
How do I shrink a WAV without leaving the WAV format?
Three lossless levers: lower the sample rate (48 kHz → 22.05 kHz roughly halves the file), switch stereo to mono (exactly half), and trim unused head/tail audio. Combined, a 24-bit / 48 kHz / stereo / 1-hour recording (~990 MB) can drop to a 16-bit / 22.05 kHz / mono trimmed clip around 40 MB — all still uncompressed PCM. For more aggressive shrinking inside WAV use the WAV Compressor; for true compression switch container to FLAC (lossless, ~50% smaller) or MP3 (lossy, ~10× smaller).
What sample rate should I pick — 44.1 kHz or 48 kHz?
44.1 kHz for anything that ends up on CD, in iTunes/Spotify-style music libraries, or matches an existing music project. 48 kHz for anything that ships with video (YouTube, Vimeo, broadcast, film, TV, podcasts that sync to video) since film/TV audio runs at 48 kHz. Mismatching forces playback to resample on the fly and can introduce subtle artefacts. If you don't know, match the destination's expected rate; otherwise keep Original.
Is there a maximum WAV file size I should worry about?
Yes — ~4 GiB. Standard WAV's RIFF header uses a 32-bit unsigned size field, capping a single file at roughly 4 GiB or ~6.8 hours of 16-bit / 44.1 kHz stereo PCM. Past that you need the RF64 extension (developed by the European Broadcasting Union) which uses 64-bit size fields. Long-form podcasts and field recordings hit this ceiling quickly at 24-bit / 96 kHz; downsampling or splitting fixes it.
Will trimming a WAV re-encode the audio?
No. WAV is uncompressed PCM, so trimming with a start time and duration writes the original samples between those boundaries into a fresh WAV with an adjusted header. The kept audio is bit-identical to the source — no generational loss, unlike trimming an MP3 or AAC.
Can I convert multiple WAV files at once with the same settings?
Yes. Drop a whole folder onto the upload area and the same sample rate, channel, and trim settings apply to every file in the batch. Useful for standardizing a sample library, normalizing field recordings from a long session, or preparing an album's worth of stems for CD prep.
What's the difference between this and the WAV Compressor?
This Convert WAV to WAV flow keeps you in lossless PCM and exposes sample rate, channel, and trim — the three knobs that change size without changing format. The WAV Compressor targets a specific output size or percentage and can drop into a different PCM variant or bitrate target to hit that number, including options that aren't strictly lossless. Use Convert when you want a specific rate or channel layout; use Compress when you want "under X MB."
Can I convert WAV to other audio formats from here?
This page only writes WAV output. For other formats use the dedicated conversions: WAV to MP3 (lossy, universal), WAV to FLAC (lossless, ~50% smaller), WAV to M4A (Apple-friendly AAC), or WAV to OGG (open-source Vorbis). All upload securely and run the same server-side conversion workflow.
