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.
