Offprint is an autonomous publishing and distraction-free reading platform that strips 100% of ads, paywalls, and cookie clutter to format web articles into two-column Charter PDF broadsheets, reflowable EPUBs for Kindle and Boox, and interactive 3D simulations.

How do I convert a web article into a clean two-column PDF offprint?

Paste any web article URL into Offprint or use the Offprint Chrome Extension / Bookmarklet. Offprint reflows the content with balanced columns, Bitstream Charter typography, drop caps, and vector SVG diagrams in under 200 milliseconds.

Can I send web articles directly to Kindle or Onyx Boox?

Yes. Offprint delivers reflowable EPUB 3.0 files and high-contrast e-ink documents directly to your Kindle or Boox e-reader with 1 click.

Is Offprint free to use?

Yes. Two-column Bitstream Charter PDF generation, distraction-free HTML reading, and e-reader delivery are 100% free with unlimited conversions.
