More eBook tools
More ways to prepare your books, using the tools already available on MobiToEpub. These additional tools currently use English.
Cover designer
Create a cover with your title, author and artwork. Download a JPEG, or apply it to the first unconverted book in your queue.
Comic to EPUB
Open CBZ, ZIP or image files, create a fixed-layout comic and download an EPUB. CBR/RAR is not supported. Check the result in your reader.
Image dithering
Adjust grayscale, contrast and dithering in an image. Download a PNG, or use it as a queued book’s cover.
File & hash inspector
View a file’s header bytes, calculate its hash and export a report. A hash identifies bytes; it does not prove who created a file.
Manuscript & field notes
Enhance a scanned image and write your own transcription and research notes. Export Markdown or TEI XML; text recognition is manual.
