The ebook converter switches files between all the major e-reader formats: upload a book, pick the target format, and get a ready file in seconds. Under the hood it runs official Calibre, the industry standard for ebook handling, so the table of contents, chapters, images and metadata all carry over.

Conversion comes in handy whenever a book's format doesn't fit your device. Amazon Kindle has traditionally favored MOBI and AZW3; PocketBook, Onyx Boox and most apps read EPUB; FB2 is common for Russian-language books; sometimes you need a book as PDF for printing or DOCX for editing. Instead of hunting down the "right" file, just convert the one you already have.

The converter accepts 30+ input formats (AZW, AZW3, EPUB, FB2, MOBI, DJVU, DOCX, PDF, CBZ, CBR and more) and outputs 20 (EPUB, MOBI, AZW3, FB2, PDF, DOCX, TXT, etc.). Files are processed on the server and deleted immediately after conversion. The maximum size is 25 MB, which covers even illustrated books and comics. The most common tasks have their own dedicated pages: EPUB to PDF, EPUB to MOBI, PDF to EPUB, FB2 to EPUB and MOBI to EPUB.
