How to Read Substack Newsletters on Your Kindle or Kobo
Substack newsletters are best read without distractions — on an e-reader, away from notifications. Substack supports Kindle directly, but Kobo users and anyone who wants better typography or offline access need a different workflow. Here are all the options.
Reading options overview
There are three main ways to get Substack content onto an e-reader:
- Send to Kindle — built into Substack, one click, Kindle only
- PDF → EPUB conversion — download PDF from Substack, convert, works on any device
- Readwise Reader — syncs your Substack inbox automatically, read in Readwise or export
Method 1: Substack's built-in Send to Kindle
The easiest option for Kindle users. No conversion needed.
- Open a Substack post in your browser or the Substack app
- Click the download icon or three-dot menu (⋯) → Send to Kindle
- If prompted, enter your Send-to-Kindle email address
- The post arrives on your Kindle within minutes
Limitation: only works for individual posts, not entire newsletter archives. Kindle only — no Kobo equivalent.
Method 2: PDF → EPUB conversion (works on Kindle and Kobo)
This gives you the best typography control and works on any e-reader.
- Open the Substack post in your browser
- Click the three-dot menu → Download PDF
- Go to pdf2epub.toolkit.bot and upload the PDF
- Download the EPUB (~30 seconds)
- Transfer to your e-reader: email to Kindle, USB to Kobo, or upload to your reading app
Substack PDFs are clean text-based files and convert well to EPUB. Font size, typeface, and line spacing are fully adjustable on the e-reader.
Method 3: Readwise Reader (automated inbox sync)
If you subscribe to many Substack newsletters, Readwise Reader can sync your entire inbox automatically.
- Sign up for Readwise Reader
- Connect your email (Reader has a dedicated email address for forwarding newsletters)
- Or use the Substack integration: Reader can import your Substack subscriptions directly
- Read in the Reader app (iOS, Android, web) — highlights sync to Readwise

Frequently asked questions
Can I read Substack on my Kindle?
Yes — there are several ways. The easiest is Substack's built-in Kindle delivery: in any Substack post, click the download icon → Send to Kindle. Substack sends the article directly to your Kindle. Alternatively, download the post as PDF and convert to EPUB at pdf2epub.toolkit.bot, then email to Kindle. For reading long newsletters or archives, the PDF-to-EPUB conversion workflow gives you better typography and font control.
How do I download a Substack post as a PDF?
Open any Substack post in your browser. Click the three-dot menu (⋯) in the top right of the post → Download PDF. The PDF downloads to your computer. For paid posts, you need to be a subscriber. Note: Substack's PDF export is only available for individual posts, not entire newsletters or archives — for bulk reading, the Send to Kindle feature is more practical.
Does Substack have a Kobo integration like it has a Kindle integration?
No — Substack's Send to Kindle feature only supports Kindle. There is no official Kobo integration. For Kobo users, the workaround is: download the Substack post as PDF, convert to EPUB at pdf2epub.toolkit.bot, then transfer to Kobo via USB or Send to Kobo. Some third-party tools (like Readwise Reader or Omnivore) can sync Substack content to Kobo more automatically.
Is the Substack PDF good quality for e-reader conversion?
Substack PDFs are clean, text-based files — not scanned images. They convert to EPUB with good results: the text flows, paragraphs are preserved, and headings are maintained. Images embedded in Substack posts are included in the conversion. The main limitation is that very long newsletters with complex formatting (multiple columns, custom design) may need a quick review after conversion.
Can I convert multiple Substack posts at once?
Currently, pdf2epub.toolkit.bot converts one PDF at a time in the free tier. For batch conversion of many Substack PDFs, the API tier supports programmatic conversion via HTTP POST. Alternatively, Readwise Reader can sync your entire Substack inbox and provides its own reading interface — useful if you subscribe to many newsletters.
