Self-publishing tools help you turn a finished manuscript into files readers can buy and shelves can stock. The stack splits into formatting, cover production, distribution, and the author website that owns your brand.
Amazon KDP remains the largest direct path for many indie eBooks and print-on-demand. IngramSpark expands catalog reach for print and library channels for many authors. Draft2Digital simplifies wide eBook distribution for writers who want less vendor juggling. Vellum is a Mac favorite for beautiful book interior files when you want polish without fighting layout software.
The short answer
Publish through KDP when you want the simplest large-market path, add IngramSpark when wider print distribution matters, use Draft2Digital to simplify wide eBooks, and format with Vellum on Mac when interiors matter.
