# YouTube to MP3 Converter (`seemuapps/youtube-to-mp3`) Actor Convert YouTube videos to MP3 audio files at 128, 192, or 320 kbps and download them straight from your run's storage. - **URL**: https://apify.com/seemuapps/youtube-to-mp3.md - **Developed by:** [Andrew](https://apify.com/seemuapps) (community) - **Categories:** Automation, Videos, Other - **Stats:** 4 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing from $0.10 / 1,000 video to mp3 results This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## YouTube to MP3 Converter Convert any YouTube video to a downloadable MP3 file at 128, 192, or 320 kbps. Paste up to 10 URLs per run and grab each MP3 straight from your run's storage. ### What you get - One MP3 file per video, stored in the run's **Key-value store** with a direct download URL - Per-video metadata in the dataset: `videoId`, `title`, `durationSeconds`, `uploader`, `fileUrl`, `fileSizeBytes` - Choice of audio quality: **128 kbps** (smaller files), **192 kbps** (recommended), or **320 kbps** (highest quality) - Residential proxy by default for reliable downloads; switch to Auto cascade if you want to try the cheaper paths first - Optional duration cap to skip overly long videos automatically ### Use cases - Save podcasts, interviews, and lectures for offline listening - Extract audio from your own uploaded videos for editing or repurposing - Archive Creative Commons / public-domain audio collections - Build training data sets from openly licensed content - Convert music videos you already own the rights to into a portable format ### How to use 1. Paste one or more YouTube URLs into **YouTube Video URLs** (`youtube.com/watch?v=...`, `youtu.be/...`, or `youtube.com/shorts/...`) 2. Pick **Audio Quality** — 192 kbps is a good default 3. Leave **Proxy Mode** on **Residential** (default) — switch to **Auto** if you want to try cheaper paths first 4. Optionally lower **Max Video Duration (seconds)** to skip long videos 5. Run the actor — MP3 files appear in the **Key-value store** tab; metadata appears in **Dataset** ### Output format Each dataset record: ```json { "inputUrl": "https://www.youtube.com/watch?v=dQw4w9WgXcQ", "videoId": "dQw4w9WgXcQ", "title": "Rick Astley - Never Gonna Give You Up", "durationSeconds": 213, "uploader": "Rick Astley", "audioQualityKbps": 192, "fileKey": "Rick_Astley_-_Never_Gonna_Give_You_Up.mp3", "fileUrl": "https://api.apify.com/v2/key-value-stores//records/Rick_Astley_-_Never_Gonna_Give_You_Up.mp3", "fileSizeBytes": 5120432, "proxyUsed": "none", "status": "success", "error": null } ```` The `fileUrl` is a public download link to the MP3 — open it in a browser, share it, or pipe it into another actor. ### Notes & limits - **Up to 10 videos per run.** For bulk jobs, schedule multiple runs. - **Max file size: 500 MB per video.** Anything larger is rejected before download. - **Age-restricted and members-only videos** require login and are not supported. - **Geo-blocked or private videos** will fail; try `Residential` proxy mode if Auto can't get past it. - Only download content you have the right to download. Respect copyright and YouTube's Terms of Service. # Actor input Schema ## `videoUrls` (type: `array`): One or more YouTube video URLs (youtube.com/watch?v=..., youtu.be/..., or youtube.com/shorts/...). Up to 10 per run. ## `audioQuality` (type: `string`): MP3 bitrate. Higher = larger file, better quality. ## `proxyMode` (type: `string`): Residential is the default and works for most YouTube content. Auto tries no proxy first, then datacenter, then residential — useful only if you want to save proxy bandwidth on videos that happen to download without one. ## `maxDurationSeconds` (type: `integer`): Skip videos longer than this. Default 3600 (1 hour). Set 0 to disable the limit. ## Actor input object example ```json { "videoUrls": [ "https://www.youtube.com/watch?v=dQw4w9WgXcQ" ], "audioQuality": "192", "proxyMode": "residential", "maxDurationSeconds": 3600 } ``` # Actor output Schema ## `results` (type: `string`): One record per video: inputUrl, videoId, title, durationSeconds, uploader, audioQualityKbps, fileKey, fileUrl, fileSizeBytes, proxyUsed, status (success|error), error. # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "videoUrls": [ "https://www.youtube.com/watch?v=dQw4w9WgXcQ" ] }; // Run the Actor and wait for it to finish const run = await client.actor("seemuapps/youtube-to-mp3").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
