Digital Signature Support

PDF includes built-in support for cryptographic digital signatures that verify document authenticity and detect tampering. Legal, financial, and government documents rely on PDF signatures for validity.

Print-Ready Output

About the MOBI Format

MOBI is an ebook format originally developed by Mobipocket SA and later acquired by Amazon in 2005 for use on Kindle devices. Based on the Open eBook standard with proprietary extensions, MOBI supports reflowable content, bookmarks, annotations, and basic formatting including images, tables, and text styles. It became the primary format for personal documents and sideloaded content on Kindle eReaders, working on every Kindle model ever produced.

Amazon has since deprecated MOBI in favor of the more capable AZW3 (KF8) and KFX formats, which support enhanced typesetting, embedded fonts, and responsive layouts. As of 2022, Amazon's Send to Kindle service no longer accepts MOBI files for email delivery. However, MOBI remains widely used for legacy Kindle compatibility and is still supported by many third-party reading apps. Converting MOBI to EPUB allows reading on non-Kindle devices, while converting to AZW3 provides a modern Kindle reading experience.
