Convertosaur
A web-to-ebook converter

Web pages,
bound to read.

Capture any article, blog post, or piece of documentation. Convertosaur turns it into a clean EPUB, PDF, AZW3 or MOBI — sent wherever you actually read.

The case for slow reading on the modern web.

The browser was once a window to the world. Today it asks too much of us: thirty open tabs, the ping of new mail, the scroll that never quite ends.

— What it makes, where it goes —

Four formats. Two destinations. One small dinosaur.

Outputs04 · formats

.epub

Open ebook standard. Reflowable, properly typeset, works everywhere.

MOBI

Older Kindle format — for first-gen and pre-2018 devices.

— How it works —

Three steps from open tab to bound file.

The extension does the work. You keep reading; we keep binding.

i.

Open any page

An article, a research paper, a 20-tab-deep documentation site. Anything readable in the browser.

Paywalled pages too — if your browser can see it, so can the dinosaur.
ii.

Click the dinosaur

Pick a format and a destination. Convertosaur strips the ads, the nav, the cookie banner — keeps the words.

The page is sent to our server, bound in memory, and forgotten on the way out.
iii.

Read on your device

Kindle, Boox, Remarkable, iPad, phone. Wherever you actually settle in to read long-form.

No new app, no setup — the file just lands where you read.
— What's in the binding —

The boring stuff, done well.

Most of the work in turning a webpage into a book is small, careful, unglamorous work. We do it.

Reader extraction

Strips ads, nav, cookie banners, and related-posts carousels — and only those.

The article body, the images, the captions, the code blocks. The rest goes in the bin.

Typography

Real ebook typography — not a screenshot in a wrapper.

Properly-set headings, paragraph indents, smart quotes, hyphenation, page numbers, table of contents.

Images

Images come along — resized, recompressed, embedded.

No broken hotlinks when you read on a train. Diagrams stay sharp; photos shrink.

Privacy

We process the page, then forget it. No reading-history log.

Conversion runs server-side. The bound file is held briefly for delivery and deleted within 24 hours — we don't keep analytics on what you've converted.

— Pricing —

Same features. Pick a budget.

Convertosaur's one real cost is server time. The plans buy you more of it.

01

Does it work on paywalled pages?

If you can read the page in your browser, Convertosaur can convert it — including subscriber-only articles, internal documentation, and pages behind SSO. The extension captures what your browser already sees.

02

What counts as a “conversion”?

One web page becomes one file. Failed conversions don't count against your weekly quota.

03

Do you track which pages I read?

No reading-history log. Page content is processed and discarded after conversion. We keep a small task record — the source URL, status, and timestamp — tied to your account so you can retry failed conversions, and the converted file is kept briefly for delivery before being deleted within 24 hours.

04

Can I convert long pages — entire books, multi-part essays?

Almost anything. The captured page (HTML or MHTML) needs to fit under a 10 MB upload cap, and there's a per-page processing time cap on top of that. Article-length and most book-length pages convert fine; pages that are unusually heavy on inline images are the most likely to hit the limit.
