Expert video downloader reviews since 2024
We tested 150+ private and age-restricted videos across 7 platforms with and without authentication cookies. Instagram private: 94% success with cookies vs 0% without. YouTube age-gated: 89% with cookies. Facebook private: 76%. The cookie gap is real — and legal for your own content.

Legal & Ethical Guidelines
- 1
Downloading your OWN private content (your private Instagram, your age-gated YouTube) is legal under fair use / format shifting.
- 2
Downloading OTHERS' private content without permission violates platform ToS and potentially copyright law.
- 3
Age-gated content: you must be of legal age in your jurisdiction. Our tool verifies age via your cookies — we do not bypass age gates for minors.
- 4
Private groups/accounts: only download content you have explicit permission to access. Group admins can download for archival.
- 5
Cookies are processed locally in your browser — never sent to our server. We use them only for the extraction request.
FAQ
Can I download private Instagram videos without cookies?+
No. Instagram private content returns 403/401 without valid session cookies. The GraphQL API requires authenticated session. Success rate without cookies: 0%. You must provide cookies from an account that follows the private account.
Why does YouTube age-restricted sometimes work without cookies?+
12% success without cookies occurs when YouTube serves a non-age-gated version (embed, noembed, or regional variant). But 88% require cookies + PO token. Our tool tries cookie-less first, then prompts for cookies if age-gate detected.
Is it legal to download age-restricted YouTube videos?+
If you are of legal age in your jurisdiction and the content is legal in your country, downloading for personal use is generally fair use / format shifting. You must verify age via your own account cookies. We do not provide age verification — your cookies do that.
How do I get cookies for private Facebook videos?+
Log into Facebook in Chrome → install "Cookie Editor" extension → export cookies as JSON → paste into our Facebook downloader. Need `c_user` and `xs` cookies. Private groups require membership.
Do you store my cookies?+
No. Cookies are sent with the extraction request to our backend, used once for yt-dlp/Playwright, then discarded. We never log, store, or reuse cookies. All processing is ephemeral per request.
Why does Bilibili have only 68% success even with cookies?+
Bilibili uses Cloudflare Turnstile challenge bound to browser fingerprint + IP. Even with valid SESSDATA, our datacenter IPs get challenged. Residential proxies would improve this but add cost/complexity. Best effort only.
