Other Video Downloaders Fail When It Matters

Crash at 90%? Network blip? Encrypted stream? Most video downloaders make you start over. Best Video Downloader doesn't.

💀

Lost Progress on Crash

Firefox updated. Your PC restarted. That 8GB download at 95%? Gone. Other video downloaders start fresh every session. Best Video Downloader writes every byte to disk immediately.

🔌

Corrupted Files on Network Drop

WiFi dropped for two seconds. Your file is now a corrupted brick. Best Video Downloader's resume means a dropped connection just pauses — it never corrupts.

🔒

Encrypted Streams? Good Luck.

HLS with AES-128. DASH manifests. Most video downloaders just give up. You're stuck screen-recording. Best Video Downloader decrypts automatically.

What Users Say

★★★★★

"Finally a video downloader that doesn't lose my progress when Firefox crashes. I download 4K concert footage and this is the only one that handles it."

Marcus K. · power user
★★★★★

"The resume feature is magic. My power went out mid-download and when I booted back up it picked up at 67%. No other video downloader does this."

Sarah L. · video editor
★★★★★

"I tried SaveFrom, Cobalt, 9xBuddy... none of them handle encrypted HLS. Best Video Downloader just works. AES-128 decryption built right in."

You've Got Questions

Is this really free?
Yes. Free tier: 1 download/day — full quality. No account, no card. Upgrade for unlimited downloads, 4K, batch, audio extraction, live DVR.
Does it work with YouTube?
The Firefox extension supports YouTube (requires the companion app for ffmpeg merging). The Chrome build excludes YouTube to comply with Chrome Web Store policies. Works with 45+ sites: Vimeo, Twitch, TikTok, Twitter/X, Bilibili, Reddit, Instagram, Facebook, Kick, VK, OK.ru, Canva, and many more. HLS and DASH fully supported.
What does "resume" actually mean?
Every byte is written to disk as it arrives. Firefox crashes, your computer restarts, network drops — reopen and it picks up exactly where it stopped. Works across reboots and days offline.
Chrome support?
Firefox only right now. Chrome is in active development. Enter your email above and we'll notify you at launch. Firefox was chosen first because its extension APIs provide superior support for resumable downloads and native messaging.
Do you track my downloads?
No. Zero tracking. We never see your browsing history, downloads, or file contents. Only data stored: your license key (if you upgrade) for validation. Everything stays local.
Refunds?
7 days, no questions asked. Email us. We built this for power users — if it's not for you, that's completely fine.
