AVI to MP3 Converter

AVI files are usually old — camcorder footage, DivX rips, clips from a decade-old phone — and the audio inside them is often the only part still worth keeping. Drop one here and get an MP3, converted locally in your browser.

工作原理

Choose your AVI

Drop the .avi file above. DivX, Xvid, MJPEG, and uncompressed camcorder AVIs all work.

Pick a bitrate

Old AVI audio is often low quality already, so 128 kbps is usually plenty. Use 192 kbps if the source is music.

Download the MP3

Preview and save. Nothing was uploaded, so even a big archive file costs no bandwidth.

主要特性

这款avi to mp3脱颖而出的原因。

Handles legacy audio codecs

AVI files carry MP3, AC-3, PCM, ADPCM, or even MP2 audio depending on their age. All of them decode here.

Old files, no modern player needed

Many current players have dropped AVI support entirely. The converter reads the container directly, so you do not need one.

No upload, no size limit

Uncompressed camcorder AVIs get enormous. Since nothing is uploaded, size is not a problem.

Fixes broken audio playback

When an AVI plays video but stays silent, the audio codec is missing from your system. Converting sidesteps the codec problem entirely.

Private by construction

Home videos and family archives never leave your computer — the conversion happens in this page.

API for bulk archives

Digitising a shelf of old recordings? Run them through /v1/convert/audio in a script.

使用场景

此工具能为您节省时间的常见场景。

Rescue audio from home videos

Keep voices and music from old family recordings even when the video quality is no longer worth storing.

Old camcorder footage

MiniDV and early digital camcorders wrote AVI. Extract interviews or ambient sound for a new project.

Archived lectures and talks

Convert a decade of recorded sessions into compact MP3s that actually play on a modern phone.

Silent AVI playback problems

If an AVI plays without sound on your machine, converting produces an MP3 that plays fine — no codec pack required.

Reclaiming disk space

Replace multi-gigabyte AVI archives with MP3s when only the audio still matters.

Transcribing old recordings

Convert to MP3, then transcribe — most speech-to-text services will not accept AVI at all.

通过API自动化

以编程方式使用相同的工具。适用于任何语言——仅需HTTP。

cURL

curl -X POST https://api.parsejet.com/v1/convert/audio \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "[email protected]" \
  -F "output_format=mp3" \
  -F "bitrate=128k" \
  -o archive.mp3

Python

import httpx
from pathlib import Path

for clip in Path("camcorder").glob("*.avi"):
    resp = httpx.post(
        "https://api.parsejet.com/v1/convert/audio",
        headers={"Authorization": "Bearer YOUR_API_KEY"},
        files={"file": clip.open("rb")},
        data={"output_format": "mp3", "bitrate": "128k"},
        timeout=300,
    )
    clip.with_suffix(".mp3").write_bytes(resp.content)

JavaScript

const form = new FormData();
form.append("file", aviFile);
form.append("output_format", "mp3");
form.append("bitrate", "128k");

const res = await fetch("https://api.parsejet.com/v1/convert/audio", {
  method: "POST",
  headers: { Authorization: "Bearer YOUR_API_KEY" },
  body: form,
});
const mp3 = await res.blob(); // audio/mpeg

想自动化处理吗？

ParseJet API 通过一个 HTTP 端点提供相同的解析能力。无需 ffmpeg、poppler 或 tesseract — 只需一次 API 调用。

curl -X POST https://api.parsejet.com/v1/parse/auto/url \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com"}'

常见问题

How do I convert AVI to MP3?

Drop the .avi file above, choose a bitrate, and click Convert. The audio track is decoded and written as MP3 in your browser, with no upload and no software to install.

My AVI plays with no sound — will converting help?

Usually yes. Silent playback normally means your player lacks the audio codec inside the AVI, not that the audio is missing. The converter decodes those codecs itself, so the resulting MP3 plays normally.

Which AVI audio codecs are supported?

MP3, AC-3, MP2, PCM, and ADPCM — the codecs found in DivX and Xvid rips, camcorder footage, and older captures. All are re-encoded to a standard MP3.

Will the MP3 sound better than the AVI?

No. Conversion cannot add quality the original never had; old AVI audio is often 96–128 kbps to begin with. Choosing 320 kbps only makes a bigger file, not a better one.

Is there a file size limit?

No, because nothing is uploaded. Uncompressed AVIs can be very large, and they convert fine as long as your machine has the memory. For very large batches, use the API.

Is it free?

The browser converter is free and unlimited. The API is free for 300 credits per month, with paid plans starting at $19/month.
