About

Never Lose a Newsletter Again — Download Any Substack Post in the Format You Love
Substack has become home to some of the most brilliant writing on the internet — investigative journalism, deep-dive research, personal essays, industry analysis, and thought leadership that you actually want to keep. But what happens when a writer moves platforms, paywalls their archive, or simply disappears? Your favorite reads vanish with them.
Substack Post Downloader puts you back in control. Save any Substack article — or your entire archive — directly to your device in the format that works best for your workflow. No subscriptions. No cloud uploads. No data sent anywhere. Just your content, on your terms.

📥 FOUR EXPORT FORMATS — ONE TOOL
📄 PDF Export
Generate clean, beautifully formatted PDF documents from any Substack post. Perfect for printing, annotating in your favorite PDF reader, attaching to emails, sharing with colleagues, or filing away for long-term reference. The PDF preserves the article's structure — headings, paragraphs, images, and formatting — exactly as the author intended. Ideal for researchers, students, lawyers, journalists, and anyone who lives inside their PDF reader.

📝 Plain Text Export (.txt)
Sometimes simplicity wins. Export a clean, distraction-free plain text version of any post — no HTML tags, no formatting clutter, just pure content. Ideal for pasting into documents, feeding into scripts, running text analysis, importing into spreadsheets, or simply reading offline without any visual noise. Works with any text editor on any device.
🗂️ JSON Export
Built for developers, data analysts, researchers, and power users. Export structured post data as JSON — including title, author, publication name, publish date, subtitle, content, tags, and more. Build your own reading apps, run NLP analysis, populate databases, create custom visualizations, or integrate Substack content into your own tools and workflows. The clean, predictable JSON schema makes automation effortless.

⚡ BATCH DOWNLOAD — YOUR ENTIRE ARCHIVE IN ONE CLICK
This is where Substack Post Downloader truly stands apart.
Don't just save one post at a time — download your entire Substack archive in bulk. With a single click, queue up every post from a publication and export them all simultaneously in your chosen format. Whether a newsletter has 10 posts or 1,000, the batch downloader handles it all intelligently — without overwhelming your browser or missing a single article.
Why batch downloading changes everything:

Full archive preservation — Back up an entire newsletter before it goes behind a paywall, gets deleted, or the writer moves on. Your archive, permanently saved.
Offline reading libraries — Build a complete offline library of your favorite publications. Read on planes, in subways, in areas with no signal — zero internet required.
Research and journalism — Academics and journalists can archive complete publication histories for citation, fact-checking, and longitudinal analysis.
Migration and import — Moving your reading life to a new tool? Export everything at once and import wherever you want.
Content analysis — Download an entire archive as JSON or TXT and run linguistic analysis, topic modeling, keyword extraction, or sentiment analysis across hundreds of posts at once.
Personal collections — Curate complete collections of newsletters you love, organized and searchable on your own device forever.


🔒 PRIVACY FIRST — ALWAYS
Your reading habits are your business. Substack Post Downloader is built with privacy as a non-negotiable foundation:

✅ Zero data collection — We collect absolutely nothing. No analytics, no tracking pixels, no usage logs.
✅ No account required — No sign-up, no login, no email address. Install and use immediately.
✅ No cloud storage — Everything happens locally in your browser. Files go directly to your device — never to any server.
✅ No third-party sharing — Your reading history, your exported content, and your behavior are never transmitted anywhere.
✅ Minimal permissions — The extension requests only the permissions it absolutely needs to function. Nothing more.
