Convert AVI to MP3 — Pull Audio from Camcorder Footage, Old Videos, and Legacy Files
AVI files are survivors from another era of computing. If you have them, they probably came from a mini-DV camcorder, an old digital camera, a Windows Movie Maker export, a VirtualDub project, or a hard drive backup you dug out of a closet. Maybe they are wedding footage, home movies from the early 2000s, or recordings from a security DVR system that only knew how to write AVI. The video might look dated, but the audio inside — the voices, the laughter, the music — is often irreplaceable. This AVI to MP3 converter reads .avi files from any era, with any codec inside, and extracts the audio as a universal MP3. DivX, Xvid, MJPEG, DV, uncompressed — it does not matter what the video was encoded with. The tool runs in your browser, so there is nothing to install and nothing to upload. If you have old AVI files collecting dust, you can change them to MP3 and preserve the sound that matters.

Why People Still Need to Convert AVI to MP3
AVI had a good run as the default video format on Windows for over a decade. There are countless AVI files sitting on old drives and backup discs. Here are the real reasons people convert them to MP3 today.
Rescuing Audio from Home Movies and Family Events
A 2004 wedding, a toddler's first words, a grandparent telling a story at Thanksgiving — these moments live in old AVI camcorder files. Convert AVI to MP3 and save those voices in a format you can listen to on your phone, share with family, or back up to the cloud. The audio is often the most precious part of the recording.
Pulling Audio from Security and Dashcam Recordings
Older security DVR systems and early dashcams recorded everything as AVI. If you need to extract audio from surveillance footage — a conversation, an incident, ambient sound for evidence — converting AVI to MP3 gives you just the audio in a small, portable file without needing to keep the full video recording.
Cleaning Up Old Project Folders and Backups
Maybe you found a hard drive full of AVI exports from Windows Movie Maker, VirtualDub, or an old version of Premiere. The video quality might not hold up, but the voice narrations, music tracks, and interviews embedded in those files can still be useful. Extract audio from AVI and free up storage while keeping what counts.
What Makes This AVI to MP3 Converter Actually Useful
AVI is a legacy format with a lot of quirks. Files can be 20 years old, encoded with codecs that no longer ship with modern operating systems, or partially corrupted from bad disc burns. Here is what this converter handles that others do not.
Reads AVI from Any Era — DivX, Xvid, MJPEG, DV, Uncompressed
AVI files span decades of encoding history. Some contain DV codec audio from camcorders. Others have MP3 or PCM audio alongside DivX or Xvid video from the download era. Early webcams and digital cameras wrote MJPEG AVI with various audio formats. This converter reads the audio from all of them and converts it to MP3, no matter how old or obscure the encoding is.
Handles Corrupted and Partially Broken AVI Files
Old AVI files have been through a lot — bad CD burns, failing hard drives, incomplete file transfers from the early 2000s. A lot of these files will not play in a standard video player, but the audio stream inside might still be intact. This AVI to MP3 converter is more resilient than most tools. If the audio data is readable, it will extract it even when the video portion is damaged or unplayable.
No Codec Packs Needed
Back in the day, you needed K-Lite Codec Pack, ffdshow, or DivX Player installed on Windows to play AVI files. Modern computers do not ship with those codecs anymore, which is why your AVI files will not open in Windows 10 or 11 out of the box. This converter sidesteps the problem entirely — it decodes the audio in the browser, so you do not need to hunt down and install old codec packs to extract audio from AVI.
Processes AVI from Security Cameras and Dashcams
Security DVR systems and early dashcams almost universally recorded to AVI. These files often use non-standard or proprietary audio codecs and odd frame rates that confuse modern software. This converter focuses on the audio stream and handles the unusual encoding patterns that security and dashcam AVI files tend to have.
Opens AVI Files That Modern Players Refuse
Tried opening an old AVI file in Windows Media Player and got nothing? Tried VLC and it played video but no audio? Or maybe your Mac just shows a blank QuickTime icon? This AVI to MP3 converter reads the file at the container level, so even files that crash or confuse desktop video players can often have their audio extracted successfully.
Converts DV Camcorder Footage — Wedding Speeches, Home Movies
Mini-DV and Digital8 camcorders recorded to AVI when you captured footage to a computer. That means your transferred wedding tapes, birthday parties, and childhood home movies are sitting in AVI files right now. Convert those AVI files to MP3 and preserve the voices and sounds in a format that will last and play on anything. These are the recordings you cannot get back if you lose them.
How to Convert AVI to MP3 — Three Simple Steps
No technical knowledge needed. If you can open a web page, you can convert AVI to MP3.
Load Your AVI File
Go to videotoaudio.net in any browser. Drag your .avi file onto the page or tap the upload area to browse for it. Found a whole folder of old AVI recordings on a backup drive? Add them all — the converter handles batches so you can process an entire archive in one go.
Pick Your MP3 Bitrate
MP3 is already selected as the output format. Choose a bitrate: 128 kbps is perfectly fine for voice recordings and family videos where the audio was never high-fidelity to begin with. 192 kbps is a good all-around pick. 320 kbps makes sense if the AVI contains music or the original audio was uncompressed PCM.
Save Your MP3
Hit convert and the AVI audio gets extracted to MP3 in seconds. Download individual files or grab everything as a ZIP if you converted a batch. Your AVI to MP3 conversion is done, and you have the audio from those old recordings in a format that will play on anything modern.

AVI to MP3 — Frequently Asked Questions
My AVI file is from a 2005 camcorder — will it work?
Yes. Camcorder AVI files from the mid-2000s typically use the DV codec for video and 16-bit PCM for audio. This is one of the easiest AVI formats to convert because the audio is uncompressed, so the converter reads it cleanly and encodes it to MP3. Does not matter if the camcorder was a Sony, Canon, JVC, Panasonic, or any other brand — the DV-AVI format was standardized across manufacturers.
What if the AVI uses the DivX or Xvid codec?
DivX and Xvid are video codecs — they affect the video portion of the AVI, not the audio. The audio inside a DivX or Xvid AVI is usually MP3 or AC3. This converter ignores the video codec entirely and reads only the audio stream, so DivX and Xvid AVI files convert to MP3 without any problems. You do not need DivX Player or any codec packs installed.
Can I convert AVI files from an old security DVR system?
In most cases, yes. Security DVR systems from companies like Swann, Lorex, Hikvision, and Dahua recorded to AVI, though some used non-standard variations. If the audio track inside the AVI is in a standard format (PCM, MP3, AAC, or ADPCM), the converter will extract it. Some proprietary DVR formats may not work, but it is worth trying — you might recover audio from files that the DVR's own software can no longer open.
My AVI file won't play in Windows 10 or 11 — can the converter still read it?
Very likely yes. Windows 10 and 11 dropped support for many older video codecs that were common in AVI files. Your file might be perfectly intact — your computer just does not have the right decoder installed anymore. This AVI to MP3 converter uses its own decoding engine in the browser, so it does not depend on your operating system's codec library. Files that are silent or unplayable in Windows often convert to MP3 just fine here.
AVI to MP3 vs AVI to WAV — when do I need uncompressed output?
Choose MP3 for everyday listening — phones, car stereos, music apps. It is small, universal, and sounds great at 192 kbps or higher. Choose WAV if you plan to edit the audio further in software like Audacity, GarageBand, or a DAW. WAV is uncompressed, so it avoids the quality loss that comes with encoding to a lossy format. If the original AVI audio is already uncompressed PCM, converting to WAV preserves it perfectly. For archival purposes or audio editing, WAV is the better pick.
Why are AVI files so much bigger than MP4?
AVI is an older container from 1992 that often holds video with less efficient compression — or even no compression at all. DV-AVI from camcorders is barely compressed, which is why a 30-minute tape can fill 13 GB. MP4 uses modern codecs like H.264 or H.265 that compress video much more aggressively. The audio size is similar between the two formats, but the video makes AVI files dramatically larger. That is exactly why extracting just the audio as MP3 is so useful — you go from gigabytes down to megabytes.
Can I convert an AVI file that has no audio track?
If the AVI file genuinely has no audio stream — just video — then there is nothing to extract and the conversion will not produce a result. Some very old screen capture tools and animation software created video-only AVI files. The converter will let you know if no audio track is found. If you think the file should have audio but it is not detected, the audio stream may be corrupted or in an extremely unusual codec.
My AVI was made with Windows Movie Maker — will it convert?
Yes. Windows Movie Maker exported AVI files with standard codecs — typically DV video with PCM audio, or occasionally Microsoft Video 1 with PCM audio. These are straightforward formats that the converter handles easily. Whether it was Windows Movie Maker from XP, Vista, or Windows 7, the AVI exports all convert to MP3 without issues.
How do I convert a folder of old home videos from AVI to MP3?
Open videotoaudio.net and drag the entire batch of AVI files onto the page at once. You do not need to convert them one by one. The converter processes all of them and lets you download each MP3 individually or grab the complete set as a single ZIP file. If you have dozens of old home videos, this is the fastest way to extract audio from AVI without installing any software.
Is the audio quality from an old AVI going to be decent as MP3?
That depends on the original recording, not the conversion. Many camcorders recorded 16-bit 48kHz PCM audio, which is actually quite good — CD quality or better. Converting that to MP3 at 192 or 320 kbps will sound excellent. On the other hand, some cheap early digital cameras recorded mono audio at low sample rates, and that audio was never going to sound amazing regardless of format. The converter faithfully reproduces whatever audio is in the AVI — it will not make bad source audio worse, but it also cannot magically improve a low-quality recording.
