Table of contents
EPUB TOC becomes clickable PDF bookmarks.

EU-hosted, GDPR
Your files are stored in Frankfurt (EU), encrypted at rest with AES-256.
Turn EPUB 3.2 ebooks — self-published Amazon KDP manuscripts, Project Gutenberg public-domain classics, ISO/IEC 14496-22 OpenType-licensed art books, academic papers exported from Pressbooks or Apple Pages — into print-ready ISO 32000-1:2008 PDFs (or PDF/A-2 archive masters under ISO 19005-2 for legal deposit and Companies Act 2006 §388 statutory retention). Chapter structure becomes clickable PDF bookmarks, the EPUB navigation document (toc.xhtml) maps to a hierarchical /Outlines tree, MathML equations render as crisp vectors, embedded OpenType and TrueType fonts subset and embed in compliance with the W3C EPUB Core Media Type spec, CSS3 page-break rules are honored and your Adobe DRM-free EPUB renders identically across Adobe Acrobat Reader DC, Apple Preview, Foxit and Microsoft Edge.

How does iFillPDF compare to CloudConvert, Smallpdf, Adobe Acrobat Pro and Calibre for converting EPUB to PDF?+
Four hard differences: (1) Pricing — CloudConvert gives 25 free conversions per day then forces $8/mo Lite (or $0.025 per conversion on pay-as-you-go) and the free tier strips custom fonts; Smallpdf gates the EPUB converter behind Pro at $9/mo (or $108/yr) after a 2-task/day cap; Adobe Acrobat Pro is $19.99/mo with a mandatory desktop install and Adobe ID sign-in; Calibre is free but is a 200 MB desktop install with a steep CLI learning curve and no neural layout repair when EPUB CSS is broken. iFillPDF gives you unlimited free use with a watermark and 0 AI Deep Detect with no card, then $8.99/mo Start for 8 AI Deep Detect/mo. (2) Standards output — only iFillPDF and Adobe Acrobat Pro produce true ISO 32000-1:2008 PDFs with optional ISO 19005-2 PDF/A-2 archive mode (required for legal deposit, IRS records retention under 26 USC § 6001, and Companies Act 2006 §388 statutory retention); CloudConvert and Smallpdf output PDF 1.7 with no archive guarantee, Calibre PDF/A support requires manual ghostscript post-processing. (3) MathML and EPUB 3.2 — Calibre handles MathML via plugin only, Smallpdf strips MathML to plain text, CloudConvert converts MathML to images (loses selectability); iFillPDF renders MathML as crisp PDF vectors per ISO 32000-1:2008 §14.10 structure trees. (4) Data residency — Smallpdf is Switzerland (outside EEA), CloudConvert is Germany (good), Adobe is US under Cloud Act 50 USC §3024 reach; iFillPDF runs on Hetzner Falkenstein eu-central-1 with SOC 2 Type II, ISO 27001:2022, ICO UK registered, files purged within 24h.
Will the PDF preserve clickable links, footnotes and the EPUB table of contents?+
Yes — three things explicitly mapped from the EPUB to ISO 32000-1:2008 PDF features. (a) The EPUB navigation document (toc.xhtml in EPUB 3.2, NCX in EPUB 2) maps to a hierarchical /Outlines tree readable as a left-pane bookmark panel in Adobe Reader, Apple Preview, Foxit and any compliant viewer — depth up to 6 levels preserved. (b) Internal cross-references (footnotes, endnotes, "see chapter 4" anchors) become PDF /GoTo destinations rendered as clickable hyperlinks with the original underline styling — readable in any PDF viewer including the macOS Preview QuickLook plugin. (c) External hyperlinks (URLs in the EPUB) become PDF /URI actions, clickable in any modern viewer. The output meets PDF/UA-1 (ISO 14289-1) accessibility guidelines including reading order tags, language declaration and structure tree — useful for academic publishers under WCAG 2.2 AA, the EU Accessibility Act 2025 (Directive 2019/882) and US Section 508 Rehabilitation Act §794d compliance. None of CloudConvert free, Smallpdf or PDF2Go output PDF/UA-1 — only Calibre (with manual ghostscript flags) and iFillPDF do.
