MP3 Audio Converter & Video Downloader

Convert audio to MP3 and save accessible MP4 videos from web pages.

MP3 Audio Converter combines file conversion, page-media detection, and supported online audio downloads in one Chrome extension. Convert recordings and media files, turn supported YouTube and SoundCloud links into MP3, or save accessible Twitter / X videos as MP4. THREE SIMPLE TABS • Convert Audio Upload a file, choose an output format, convert it, and download the result. Use it to make recordings easier to share, prepare audio for editing, or extract sound from supported media files. • Page Audio Scan the current page for accessible audio sources. Download individual files or multiple detected audio files when available. • Page Videos Find video players on the current page, with videos visible on your screen listed first. Refresh after scrolling to scan again. Download complete, accessible MP4 files when the source exposes them. YOUTUBE AND SOUNDCLOUD TO MP3 Use the extension with the YouTube-to-MP3 and SoundCloud-to-MP3 pages on mp3audioconverter.com. Paste a supported public link, start the task, and follow progress in a panel on the page. The extension uses your browser connection to retrieve accessible source media and can process supported audio locally. Availability depends on the source platform, the media format, and any access restrictions. TWITTER / X VIDEO DOWNLOADS Paste an individual Twitter or X post link into the website’s Twitter Video Downloader. The extension checks the matching open post and available public metadata for a complete MP4. When multiple supported variants are exposed, it selects the highest-ranked option it detects. The suggested filename uses a short extract of the post text and the post ID. Your browser or download manager may apply its own naming rules. Twitter / X video downloads use your browser connection. The video is not downloaded through or uploaded to our conversion server. HOW TO CONVERT A FILE 1. Open MP3 Audio Converter from your Chrome toolbar. 2. Choose Convert Audio. 3. Drop a file into the upload area or select it from your computer. 4. Choose the output format. 5. Click Convert File. 6. Download the result when processing finishes. HOW TO FIND PAGE MEDIA 1. Open the page containing the audio or video. 2. Open the extension. 3. Choose Page Audio or Page Videos. 4. Review the detected sources. 5. Download an accessible file, or refresh the video list after scrolling. IMPORTANT LIMITATIONS This extension cannot download every video or audio stream. Some websites use temporary blob URLs, segmented streaming, separate audio and video tracks, private links, login restrictions, or protected media. A video playing in your browser does not necessarily mean a complete downloadable MP4 is available. Reddit and YouTube video downloads depend on the available source. Separate-stream merging is not currently supported by the Page Videos feature. Some detected video files may not contain an audio track. The extension does not bypass DRM or access restrictions. Only download or convert content you own or have permission to use, and respect applicable copyright rules and website terms. PRIVACY AND FILE HANDLING Files selected for ordinary file conversion are uploaded to mp3audioconverter.com for processing. For supported YouTube and SoundCloud workflows, source media is retrieved through your browser connection and local processing is attempted. Completed MP3 files may be uploaded to create temporary download-manager links. If local encoding fails, supported downloaded media may be uploaded for server-side conversion. Size and processing limits apply. Twitter / X MP4 downloads use your browser connection without uploading the video to our server. Page-media detection runs when you use the relevant feature. It inspects media associated with the current page and is not intended for browsing-history tracking. Visit mp3audioconverter.com for the full converter, audio cutter, and additional audio tools. Online-platform features require an extension release that includes them. Website availability does not mean an older installed extension supports every feature.
