Common Questions About Preserving Substack Audio, Video & Images

Paste any public Substack URL into the box at the top of this page and press the preserve button. Soundc reads the Substack link, fetches the source media, and streams the MP4 file back to your browser without storing it on our servers.

Yes — free users get a generous daily allowance for Substack downloads. Paid plans remove the cap if you batch many Substack URLs in a session.

Substack hosts a mix of video, photo, and audio. Soundc matches whatever the source post delivered — usually MP4, JPG — at up to 1080p.

No. Substack exposes its content publicly without a sign-in wall, so Soundc can preserve any public URL you paste — no Substack account required, no Soundc account either.

Substack delivers fairly standard content endpoints, so Soundc preserves what Substack streams without extra workarounds. The main limits are public visibility and the originating uploader's quality settings.

Substack serves a wide audience and so does Soundc — creators archiving their own work, fans saving favorites before they get pulled, and researchers building reference collections all paste Substack URLs into Soundc daily.

Soundc preserves one Substack URL per submission. For a channel or playlist, paste each video URL individually — Substack's grouping pages are navigation shells, not single-file endpoints.

Substack on mobile and Soundc on mobile are a natural pair. Open Soundc in your phone's browser, paste a Substack URL from the share menu, and the file lands directly in your device's downloads folder.

Soundc routes Substack audio requests through the extraction path tuned for that file type. The general Substack tutorial works too, but the audio-specific page surfaces the right options up front.

Neither. Soundc reads Substack's public delivery endpoints exactly the way a normal browser does — no API key, no charged request, no notification back to Substack or to the original uploader.

Substack occasionally changes how its delivery endpoints are structured. When that happens, Soundc patches the extractor usually within a day or two — recheck shortly, or paste a different Substack URL to confirm it isn't a one-off post.

Directly in your browser's default downloads folder. Soundc doesn't keep a copy on our side — once the Substack file lands on your device, it's yours alone.
