Everything you need in a free MOBI to PDF converter
MOBI to PDF in one click
Turn Kindle .mobi and .azw3 ebooks into shareable PDFs without installing Calibre or creating an account.
A4 or Letter pages
Pick the page size that matches your region or printer, then download a clean PDF ready to archive or print.
100% browser-based
Conversion reads your ebook locally, walks chapters in order, and builds a PDF on your device. Nothing uploads to Focera.
Drag & drop workflow
Drop a MOBI or AZW3 up to 25 MB, choose a page size, convert, preview a text summary, and download in a few clicks.
How It Works
Converting MOBI to PDF should be quick and private. Focera keeps the whole flow on one page — upload a Kindle ebook, pick a page size, convert, and download without an account or desktop installer.
- Upload your MOBI. Drag and drop a DRM-free .mobi, .azw, .azw3, or .prc file up to 25 MB, or click the zone to browse from your device.
- Choose page size. Use A4 for international documents or Letter for US-sized pages.
- Convert and download. Click Convert to PDF. Chapters are read in order, rendered locally, and the PDF downloads automatically — preview a text summary in the panel.
Jump back to the MOBI to PDF converter anytime to process another file.
What About Formatting?
Reflowable MOBI and KF8 (AZW3) books with headings, paragraphs, lists, links, and embedded images convert best. Stylesheets from the book are applied when possible. Fixed-layout comics, complex CSS, custom fonts, and interactive features may simplify or look different after conversion.
DRM-protected Kindle store books cannot be opened in the browser. Export or download a DRM-free MOBI/AZW3 before converting.
Popular Use Cases
- Print a chapter or book — Convert to A4 or Letter PDF for home or office printing.
- Share read-only copies — Send a PDF when recipients do not have a Kindle app installed.
- Archive for long-term storage — Keep a fixed PDF alongside the original MOBI.
- Annotate elsewhere — Open the PDF in tools that highlight and comment more easily than ebook readers.
Private by Design
Your MOBI is read and converted entirely in your browser. Focera does not receive the ebook, store chapters, or run conversion on a remote server. When you leave the page, object URLs are revoked and nothing remains on our infrastructure.
