Online MP3 WAV and OGG audio converter

Start by selecting the file in the widget above. Choose a compatible MP3, WAV, OGG or WebM file. Then set the output format and start the conversion. When processing is complete, download the new file to the same device and check that its name, duration and format match what you need.

The browser reads the selected file and performs the conversion locally. The audio does not need to travel across the internet to an external service. You still need to open the site and keep the page loaded. If you close the tab, block the browser or put your phone into an aggressive power-saving mode, processing may stop.

This workflow handles quick studio tasks. You can convert a guitar demo to WAV before editing, turn a recording into an MP3 to send to the rehearsal group or prepare an OGG version for a digital project. A 3 minutes and 20 seconds folk demo may be easier to share as an MP3 than as a WAV, while separate vocal and drum tracks should remain in WAV during editing.

The result depends on the original file and the options offered by the selected format. If the source is an MP3 at 128 kbps, converting it to WAV creates a larger file but does not restore the high frequencies, transients and ambience removed during compression. If the source is WAV, converting it to MP3 reduces the file size and may reduce fidelity, especially in cymbals, sibilant vocals, long reverberations and instruments with significant high-frequency content.

Before deleting the source, compare both files. Check the beginning, loudest section and end of the song. In a rock recording, listen to the attack of the drums and cymbals. In a worship ballad, check the tail of the vocal reverb. These sections reveal changes more easily than a quick listen through a phone speaker.

To record a new idea before conversion, use Cantivy's audio recorder. Then compare the original file with the converted copy and decide which version works best for editing, rehearsal or sharing.

WAV is a container that commonly stores uncompressed PCM audio. In stereo, at 44.1 kHz and 16 bits, the calculation is about 10.1 MB per minute. At 48 kHz and 24 bits, the size is close to 17.3 MB per minute. A 5-minute stereo recording may take approximately 50.5 MB at 44.1 kHz and 16 bits, or about 86.5 MB at 48 kHz and 24 bits. The exact amount varies according to the channels and metadata.

WAV preserves the samples in the exported file, without the perceptual reduction typical of MP3. That does not make every WAV better than every other file. A WAV created from an MP3 remains limited by the source MP3. The benefit is working with a predictable format for cuts, fades, take alignment, mixing and repeated processing.

MP3 uses lossy compression. The codec removes parts of the signal considered less audible and stores the remainder in less space. Bitrates of 128, 192, 256 and 320 kbps are common. A stereo MP3 at 320 kbps takes approximately 2.4 MB per minute; at 128 kbps, it is close to 0.96 MB per minute. An MP3 at 320 kbps usually stays closer to the source than one at 128 kbps, but it is still a compressed version.

In a country track with vocals, guitar, bass and drums, the difference between 128 and 320 kbps may appear in the cymbals, reverberations, vocal consonants and space between the instruments. In speech recorded in a quiet environment, the difference may be less obvious, although the file remains subject to the characteristics of the codec and conversion.

OGG is a container that commonly uses the Vorbis codec, although the extension is also associated with other codecs on some systems. It works well for digital applications and can provide a suitable balance between size and quality. The bitrate number should not be compared directly with an MP3's as though the codecs were identical.

WebM is a container frequently used on the web. It commonly carries codecs such as Opus or Vorbis, but support depends on the specific combination used in the file. A browser may play a particular WebM, while a DAW, television or older device may reject it. Check the destination before converting an entire library.

In practice, converting between formats is not just changing the extension name. Each format organizes data differently and may apply compression. When studying free tools for making music, also check whether your editor accepts the chosen codec, whether the file keeps the expected sample rate and whether the project works in mono or stereo.

For rehearsal, MP3 is usually enough. If you are sending a backing track to a rock band by phone, a file at 192 or 256 kbps offers a reasonable size and makes downloading easier. For a vocal reference or guitar demo, the goal is to hear the arrangement, tempo and structure, not to create a final mix. If the group needs to respond within a few minutes, convenience matters more than a few megabytes.

Use 128 kbps only when file size is a clear priority, such as with a very short preview or limited connection. For a complete song with drums, horns and vocals, 192 kbps is usually a more comfortable choice. When evaluating a country arrangement, 256 kbps reduces the chance that the cymbals and ambience will sound excessively compressed. These values are practical references, not a guarantee of the same result for every file.

For distribution, follow the platform or aggregator's specifications. MP3 at 320 kbps is common for lightweight deliveries, while WAV is preferable when the service requests an uncompressed file. If you are preparing a worship track for mastering, export the final version from the original project in WAV, keeping the requested resolution. Do not use an MP3 converted to WAV as though it were an original master.

For editing, mixing and recording, choose WAV whenever possible. DAWs such as Ableton Live, Reaper, Pro Tools and other editors work well with PCM. The format makes cuts, fades, take alignment, automation and repeated processing easier. For video, 48 kHz is a frequent choice. For music and CD, 44.1 kHz is common. Set that rate in the project before importing multiple files.

If the project is already at 48 kHz, avoid converting every individual track without a reason. If the files arrive at 44.1 kHz and the destination requires 48 kHz, perform a planned conversion and keep copies of the sources. The same care applies to bit depth: do not turn a 16-bit preview into a supposed 24-bit original.

If you are creating a folk track and need to review its structure, use WAV during editing and generate an MP3 copy for listening only. You can also consult the BPM counter to check whether a demo is, for example, between 60 and 72 BPM for a ballad or near 128 BPM for a dance arrangement. For other stages, see all Cantivy tools.

When you convert MP3 to WAV, the program decompresses the data and writes the samples to an uncompressed container. The final file may be five, ten or even twenty times larger, depending on the bitrate, number of channels and duration. A stereo MP3 at 128 kbps takes about 0.96 MB per minute, while a stereo WAV at 44.1 kHz and 16 bits takes approximately 10.1 MB per minute.

The increase in size does not represent recovered quality. The WAV now carries exactly the audio decoded from the MP3, not the recording that existed before compression. If the MP3 lost drum transients, frequency extension or part of the ambience, the WAV cannot reconstruct that data from the remaining samples.

Think of a small photo that you save as a large file. The new file takes up more space, but it does not restore the pixels that were removed. Audio works the same way. An MP3 at 128 kbps may lose transients, ambience and frequency extension. Converting that file to WAV does not recreate this information. The proper way to preserve quality is to start with the original WAV or another lossless file.

This does not mean that converting MP3 to WAV never makes sense. WAV may be necessary to import audio into a program that does not accept MP3, align a track with video, apply an editing workflow or meet a technical requirement. Keep the right expectation: you improve compatibility and avoid immediate additional compression, but you do not improve the source.

If the file is already an MP3, avoid the sequence MP3 to WAV for editing and then WAV to MP3 several times. Each new lossy conversion may change the result further. Keep the original MP3, edit it once and export the final version in the requested format. If the project is a voice recording, identify the sibilant section and the music section before choosing the output bitrate.

To learn how to structure a track before exporting, read the guide on how to compose a song.

Sample rate indicates how many measurements of the signal occur per second. At 44.1 kHz, the system records 44,100 samples per second. At 48 kHz, it records 48,000. This choice affects the range of frequencies that can be represented and should match the project. Music commonly uses 44.1 kHz; video frequently uses 48 kHz. Changing 44.1 to 48 kHz does not create new details or fix a recording captured with a poor microphone.

Bit depth describes the precision of each sample. 16 bits is the CD standard. 24 bits provides more room to work with low levels during recording and mixing. This does not mean that a 24-bit WAV is automatically better for every playback situation. The benefit appears mainly in dynamic control and the working headroom of the production process.

During recording, keep peaks away from 0 dBFS to prevent clipping. A vocal recording with digital distortion will not be fixed by converting from 16 to 24 bits. Likewise, changing 44.1 kHz to 48 kHz does not restore frequencies that were never captured. The format must be supported by good recording technique, appropriate levels and a controlled environment.

Bitrate is the amount of data used per second in compressed formats such as MP3. A stereo MP3 at 128 kbps uses less data than one at 320 kbps. A higher bitrate usually preserves more information, but it also creates a larger file. With OGG and Opus, a direct comparison with the MP3 number is not always fair because the codecs use different strategies.

For a voice recording that will still be edited, prefer WAV at 44.1 kHz or 48 kHz, with 24 bits when the equipment and software allow it. To send a preview of a country arrangement, MP3 at 192 or 256 kbps may be sufficient. For listening closer to the original file, use 320 kbps and keep the WAV stored.

If you do not know which audio format to choose for recording, use WAV and confirm your editor's or destination's requirements. For a typical music production, 44.1 kHz and 24 bits are a practical choice. For a soundtrack that will be synchronized with video, 48 kHz and 24 bits usually fit the project better.

The converter was designed to process audio in the browser. Instead of uploading the file to a remote machine, the page uses your own device's resources to read, convert and make the result available. This reduces exposure for demos, vocals, stems, interviews and recordings that have not yet been published.

Local processing does not mean that the page works without the internet. You need to open the site and keep the page loaded to use the tool. After the file is selected, conversion happens in the browser. The time varies according to the audio duration, format, available memory and the performance of the phone or computer. A 30-second file tends to finish before a 90-minute recording, especially on a phone with little free memory.

If conversion is slow, close demanding tabs, stop other downloads and keep the device connected to power when using a long file. Do not lock the screen if the system suspends the browser when you do so. With important files, check the result before deleting the source.

Even with this model, take care with the environment where you work. Avoid leaving sensitive files in a shared folder, keep the browser updated and confirm the file name before downloading the conversion. If you want to understand how Cantivy handles data and browsing, see the privacy policy.

To create a reference without installing a program, you can combine the converter with create music with AI and then export the material in the format that suits your workflow. The file remains under your control, and you choose when to share the final version.

• Use WAV for recording, editing, mixing and delivering a master without additional compression.
• Use MP3 for rehearsal, previews and quick sending. Consider 192 or 256 kbps for backing tracks and references, and 320 kbps when you want listening that is closer to the source.
• OGG and WebM work well for digital projects, but compatibility should be checked before sending.
• Converting MP3 to WAV increases the size and may make importing into an editor easier, but it does not restore lost information.
• 44.1 kHz is common in music; 48 kHz is frequently used in video.
• 16 bits meets the CD standard; 24 bits provides more headroom during recording and mixing when the project and equipment allow it.
• The converter processes the file in the browser and does not require uploading it to a remote server.
• The page must remain open and loaded. Conversion time depends on the file size and device performance.
• Keep the original file and use the conversion as a copy intended for a specific purpose.
