I wanted to build a tool that could support many platforms with a unified interface.</p> <h2> The Idea </h2> <p>People often want to save videos or media from social platforms for offline viewing, archiving, or sharing.</p> <p>However, each platform usually requires a different downloader tool.</p> <p>So I decided to experiment with building a <strong>multi-platform media downloader</strong> that works directly in the browser.</p> <p>Users only need to paste a link and the tool generates download options.</p> <h2> Supported Platforms </h2> <p>Currently the tool supports many platforms including:</p> <ul> <li>TikTok</li> <li>Douyin</li> <li>Instagram</li> <li>Facebook</li> <li>YouTube</li> <li>Twitter / X</li> <li>Vimeo</li> <li>Reddit</li> <li>Bilibili</li> <li>Dailymotion</li> <li>Pinterest</li> <li>Imgur</li> </ul> <p>Some audio platforms are also supported such as:</p> <ul> <li>SoundCloud</li> <li>Mixcloud</li> <li>Spotify</li> <li>Deezer</li> <li>Tidal</li> <li>ZingMP3</li> <li>Bandcamp</li> </ul> <p>The goal is to support as many platforms as possible while keeping the interface simple.</p> <h2> How It Works </h2> <p>The workflow is straightforward:</p> <ol> <li>Copy the media URL</li> <li>Paste it into the downloader input</li> <li>The system processes the link</li> <li>Download options are generated</li> </ol> <p>Everything runs directly in the browser so no installation is required.</p> <h2> Why I Built This </h2> <p>This project started mostly as a learning experiment.</p> <p>I wanted to explore:</p> <ul> <li>handling media extraction from different platforms</li> <li>building a fast web interface</li> <li>improving user experience for simple tools</li> </ul> <p>It also turned into a useful side project.</p> <h2> Future Improvements </h2> <p>There are still many improvements planned:</p> <ul> <li>better UI/UX</li> <li>support for additional platforms</li> <li>faster media processing</li> <li>improved mobile experience</li> </ul> <h2> Project </h2> <p>Project name: <strong>J2Download</strong></p> <p>Website:<br><br> <a href="https://j2download.com" rel="noopener noreferrer">https://j2download.com</a></p> <p>If anyone has feedback or suggestions, I’d love to hear them.</p> webdev opensource sideprojects javascript
