AI network + GDPR-compliant server
Frankfurt (EU) hosting, AES-256 at rest, files deleted within 24h.
Turn DRM-free Mobipocket / KindleGen MOBI ebooks (PalmDOC compression, HUFFDIC, the legacy MOBI 7 wrapper Amazon retired in August 2022) into a fully-typeset ISO 32000-1:2008 PDF — chapters, italics, footnotes, embedded images and the OPF navigation map become clickable PDF bookmarks. Optional ISO 19005-2 PDF/A-2 archival output for personal-library retention or print-on-demand. AI rebuilds typography (kerning, hyphenation, drop caps) where the original NCX TOC is malformed — common in pre-2011 MOBI files exported by Calibre, Mobipocket Creator and KindleGen. Hosted on Hetzner Falkenstein eu-central-1 under TADPF — AES-256 at rest, TLS 1.3, SOC 2 Type II, ISO 27001:2022, GDPR Art. 5(1)(c), zero Cloud Act 50 USC §3024 exposure, files purged within 24h.

Frequently asked questions
Is it really free?+
Unlimited free use with a watermark and 0 AI Deep Detect, then $8.99/mo Start for 8 AI Deep Detect/mo.
Is my data private?+
Frankfurt (EU) hosting, AES-256 encryption at rest, files deleted within 24h. GDPR-compliant, never used to train third-party AI.
Are MOBI files protected by Kindle DRM converted?+
No — out of respect for 17 USC §1201 (DMCA anti-circumvention, US Copyright Act) and EU Directive 2001/29/EC Art. 6 (InfoSoc Directive technological protection measures). We accept only DRM-free MOBI files: your own NaNoWriMo manuscripts, Project Gutenberg public-domain ebooks (cleared under 17 USC §304 expired-copyright rules), Smashwords / Standard Ebooks DRM-free purchases, Kindle Direct Publishing author copies and corporate whitepapers exported via KindleGen. For Kindle Store DRM-protected purchases, Amazon expects you to read on-device or via Kindle Cloud Reader — third-party tools like Calibre + DeDRM plugin operate in a US legal gray zone (and remain illegal in France under L335-3-1 of the Code de la propriété intellectuelle).
My MOBI is old (pre-2022), is it compatible?+
Yes — we handle every MOBI variant Amazon and Mobipocket ever shipped: the legacy 1996-2011 MOBI 6 / MOBI 7 (PalmDOC + HUFFDIC compression, retired by Amazon on August 1, 2022 when KindleGen was discontinued), MOBI 8 / KF8 hybrid files (2011-2022), and pure AZW3 wrapped as MOBI. Our AI rebuilds malformed NCX TOC, fixes the broken paragraph-break heuristic in early Mobipocket Creator exports and re-encodes orphaned UTF-8 glyphs that Adobe Acrobat $19.99/mo and Smallpdf $9/mo render as black squares. For comparison: Calibre handles the same files but requires a ~150 MB desktop install, 10-20 minutes of setup tuning per output profile, and crashes on PalmDOC files larger than 100 MB on Apple Silicon.
