Your Questions Answered: Saving Substack Videos, Photos & Audio with Instag

Paste any Substack URL into the box above and press Download. Instag does not require you to sign in to Substack — public links work out of the box.

Substack hosts both video and images, so Instag delivers MP4 for clips and the original image format (JPG, PNG, WebP, or animated GIF) for photo posts.

Substack caps at 1080p Full-HD for most uploads. Instag pulls whichever the platform actually served — typically the same resolution you see playing on the site itself.

Instag treats Substack URLs the way the platform itself serves them — no transcoding, no quality re-encode, no metadata stripping unless the source already lacks it.

Most Substack downloads are people saving content for personal offline viewing. Instag does not charge per download, does not require an account, and does not log what you saved.

Substack is a social network where the same URL can resolve to a video, a photo, an album, or a profile. Instag inspects the URL pattern and routes to the right extractor.

Substack does not impose a daily limit on downloads through Instag. You can save as many items as you like, one URL at a time or in a batch from the same post.

Substack downloads from Instag are MP4 (H.264/AAC). That plays on every iPhone, Android phone, smart TV, and console without re-encoding.

Downloading from Substack through Instag is free. There's no credit card, no sign-up, and no per-download quota on the free tier. Premium (Pro) removes ads and adds batch downloads — neither is required for basic Substack saves.

Saving Substack content for personal use is generally fine; redistributing copyrighted material without permission is not. Instag does not own or license Substack content — you are responsible for how you use what you download.

Instag does not retain Substack URLs you submit, the files produced, or any account info. Downloads stream through and are discarded; there is no per-user history page because there is no history.

If a Substack download fails, double-check the URL is the exact public link (not a logged-in app deep-link). If the URL works in an incognito tab, Instag should handle it too.
