What file formats can I upload?

You can upload any standard PDF file. We support PDFs created with Canva, InDesign, Affinity Publisher, Figma, and any other design tool that exports to PDF.

What is fixed-layout EPUB?

Fixed-layout EPUB preserves your exact page design — images, fonts, columns, and formatting stay exactly where you placed them. Unlike reflowable EPUBs, your pages look identical on every device.

Which platforms can I publish to?

MJ Convert Systems generates files compatible with Amazon Kindle (KDP), Apple Books, Kobo, Google Play Books, and Barnes & Noble.

How accurate is the conversion?

Every page is scored with automated SSIM drift analysis against your source PDF before export — industry-leading layout fidelity with validated-range metrics rather than a single fixed percentage for all documents.

Is there a free trial?

Yes — checkout includes a 7-day trial when enabled, with up to 5 trial conversions. A card is collected at checkout (Stripe). Cancel anytime before the trial ends to avoid charges.

Why not just use Calibre?

Calibre is great for reflowable text-heavy eBooks, but it breaks designed layouts. MJ Convert Systems uses fixed-layout EPUB conversion to preserve your exact design with images, columns, and custom formatting intact.

Visual Proof: Side-by-Side ComparisonThe homepage displays a live comparison of a 48-page Summer Cookbook. On the left: the source PDF (Page 12, "Summer Grilled Peach Salad") showing food photography with a two-column ingredient-and-method layout at 8.5 × 11 inches. On the right: the MJ Convert Systems converted output — an identical fixed-layout EPUB page with a green "0.3% drift" badge. An overlay shows: Layout match 99.7%, Text fidelity 100%, Image placement 99.5%. Export is blocked until all pages meet threshold.Technical Delta: Flattened PDF vs MJ Convert EPUBA flattened PDF merges all layers into a single raster bitmap per page. Text exists only as pixels — unselectable, unsearchable, and inaccessible to screen readers. MJ Convert Systems uses pixel-sampling AI to reconstruct selectable text layers, heal the background behind extracted text, maintain 0.3% coordinate drift, and auto-inject EAA 2026 accessibility metadata. The output EPUB has live searchable text, full TTS support, and passes validation for Amazon KDP, Apple Books, and Kobo.Built for Design ToolsWe handle the complex layouts that other converters break — designed pages with images, columns, and custom formatting.
