Paste the source HTML
Paste the page source returned by Instagram. The field is limited to 5 MB; do not paste passwords or account credentials.
About the Private Instagram Downloader

Use this workflow only for content you are allowed to view and save. Never paste a password, cookie, login token, or unrelated personal data into the form.

Private downloader FAQ
Does FastVid ask for my Instagram password?
No. FastVid never asks you to paste an Instagram password, cookie, or login token. The workflow uses source data that you choose to copy from your own browser session, so your credentials stay in your browser.
Can I use this for any private account?
Only use it for content you are authorised to view and save. FastVid does not bypass account permissions; you must already be able to access the private post in your own Instagram session.
Why is the generated request URL needed?
The generated URL points your browser to the Instagram response needed for extraction while keeping your existing session in your own browser. Open it in the same browser where you can already view the private post, then copy the returned source data into FastVid.
Why did extraction return no media?
The source may be incomplete, expired, restricted, or different from the response FastVid expects. Make sure you copied the complete page source from the generated request, then retry with the same authorised browser session. FastVid cannot recover media that Instagram did not return.
Is the source HTML stored?
No. FastVid processes the submitted source only for the current extraction request and does not write it to an application database or activity log. After the request finishes, FastVid has no stored source copy to retrieve; never paste a password, cookie, or access token into the form.
