MDPI (Multidisciplinary Digital Publishing Institute) is one of the world's largest open-access publishers, producing over 400 peer-reviewed journals across science, technology, medicine, engineering, and social science. All articles are freely available as PDF under CC BY — no paywall, no login.
MDPI PDFs use standard two-column academic layout with embedded figures. Converting to EPUB gives you a clean single-column reflowable document for reading on a Kindle or Kobo with adjustable font, night mode, and offline access.

Yes. MDPI (Multidisciplinary Digital Publishing Institute) is a fully open-access publisher — every article in every MDPI journal is published under Creative Commons CC BY licence. PDFs are freely available to anyone without paywall or institutional login. Go to any article page on mdpi.com and click the Download PDF button.
MDPI publishes over 400 peer-reviewed open-access journals spanning chemistry, biology, medicine, physics, engineering, mathematics, social sciences, and humanities. The most widely read include Molecules (chemistry), Sensors (engineering), International Journal of Molecular Sciences (IJMS), Nutrients, Sustainability, Remote Sensing, and Materials.
MDPI is a legitimate peer-reviewed open-access publisher indexed in PubMed, Scopus, and Web of Science. However, MDPI has received criticism for rapid peer review timelines and high article volumes — some in the academic community view this as a sign of lower selectivity. Evaluate individual articles on their evidence and methodology. For high-impact findings, check citation counts and whether the paper has been replicated or critiqued.
MDPI publishes a good HTML article view for desktop browsers, but it requires an internet connection and is not optimised for e-reader offline reading. Converting to EPUB gives you a single-column reflowable file for a Kindle or Kobo with adjustable font, night mode, and offline access — useful for reading during commutes or when away from a screen.
MDPI supplementary files are published as separate PDFs or data files. Download the supplementary PDF and upload it to toolkit.bot just as you would the main article PDF. The resulting EPUB can be added to your e-reader alongside the main article EPUB for complete offline access to the paper and its supporting data.
