Chrome Extension · Productivity
Download any Substack post — or an entire publication archive — as clean, high-fidelity Markdown, HTML, or PDF files. One-click conversion, perfect offline rendering, and local media bundling, all inside your browser.
Stop relying on messy screenshots or tools that strip out formatting. Preserve typography, layout, and images locally for a permanent, offline-ready personal library.
What it does
Save the current post instantly as a standalone HTML file, cleanly formatted Markdown, or a print-ready PDF — via the social-bar integration or floating action buttons.
Back up entire publication feeds in bulk. It pages through Substack's native backend in the background, extracting every article — no manual infinite-scroll required.
Target a specific archive span. Set start and end date boundaries; the background queue downloads matching articles and stops early once the timeline passes your threshold.
Content is saved in a clean, nested layout —
Downloads/Substack/[Publication]/[Date] [Headline]/ — with images
downloaded, extension-resolved, and mapped via relative links under
images/.
Choose Standard ([Pub] - YYYY-MM-DD - [Headline]) or
Date First (YYYYMMDD [Headline]) for chronological
sorting. A strict Unicode sanitizer keeps paths OS-safe.
Because it fetches articles from your active browser context, it carries your login session — enabling high-fidelity extraction of any paid, premium, or private content you already have access to.
How it works
Open any Substack article or the publication's /archive page.
Launch the Bulk Downloader panel or click the Save Post buttons.
Choose Checked Checkboxes, All Archive, or Date Range.
Watch files download sequentially with rate-limit delays that respect server capacity.
Privacy & security
All extraction, cleaning, and file construction happen directly inside your browser.
No third-party servers, analytics, or telemetry of any kind.
Respects your subscription permissions — accessing only content you are actively logged in to read.
Newsletter enthusiasts, researchers and analysts building searchable local caches, and students or writers keeping offline references with media intact.
