Guide

This guide explains what sparkdownloader can and cannot do, how media processing works in the browser, and how to use the tool for public content you are allowed to access.

How the downloader works

Paste a public media page link into the downloader and the app detects the platform before asking the parser for available media information. The result screen shows the formats that can be reached from that public link at the time of the request.

Sparkdownloader does not host a library of media files. It resolves links only when you submit them, then lets your browser save the available video, audio, image, or HLS/M3U8 stream to your device.

Supported public link types

The tool is built for public pages that expose usable media information, including videos, audio, image posts, carousels, article media, and HLS/M3U8 streams on supported platforms.

Private, deleted, region-limited, login-only, paid, member-only, or copyright-restricted content may fail or be intentionally unsupported. If a source platform changes its page format or request rules, support can also change.

Browser-local processing

Audio extraction, video and audio merging, and many HLS download tasks run locally in your browser with WebAssembly tools when possible. This keeps user-selected files on the device instead of uploading them to a conversion server.

A same-origin proxy is used only as a compatibility fallback when a browser cannot fetch a public resource directly. Large files can still be limited by browser memory, storage permissions, or network conditions.

Responsible use

  • Use sparkdownloader only for content you created, content with permission from the rights holder, or public content you are legally allowed to save.
  • Do not use the service to bypass paywalls, memberships, copyright controls, login restrictions, or platform access rules.
  • Do not use the service for mass automated downloading, scraping, reposting, or redistribution of other people’s media.
  • When in doubt, check the source platform terms and the rights holder’s permissions before downloading.
