Multi-thread segmented downloads, resume from breakpoint, task queue, global speed limit and proxies are all free, covering every download capability you use day to day. It's not a trial and has no expiration date.
Both HLS (m3u8) and DASH (mpd) segmented streams download: segments are fetched in parallel and merged into standard MP4 automatically. AES-128–encrypted streams are handled too (the key is fetched and decrypted automatically). Both common DASH addressing schemes (segment template and single-file index) are supported — the single-file index type usesmulti-thread segmented acceleration, so even a whole stream can max out bandwidth.
Batch tasks and collection downloads, subscription following (new content only), model-repository batch downloads, auto-shutdown after download, subtitle download, 4K / 8K tiers and video trimming and transcoding — all of them are about saving time and processing media.
The Free edition's core download capabilities (multi-thread, resume from breakpoint, task queue, speed limit, proxies, quality selection) are unrestricted, with no cap on count or bandwidth. When you needbatch adding, downloading multiple tasks at once, or downloading an entire collection — these efficiency features — upgrade to Pro then; the Free edition never stops working because of it.
Install it and start downloading; upgrade to Pro when you need batching, automation and media processing.
