Ebook conversion for United States
Convert EPUB to PDF or PDF to EPUB online for free — designed for US self-publishing authors. Whether you need a PDF proof for beta readers, a print-ready file for Amazon KDP, or an EPUB version of your PDF manuscript, this tool converts your file in seconds with no signup required.
Use the converter when you need a quick proofing file, a reader-shareable PDF, or a starting EPUB before the production-ready version is built properly.
How it works
The flow should be simple enough to use quickly and structured enough to produce a useful publishing decision.
Upload the source file
Start with the current EPUB or PDF you need to repurpose for proofing, review, or platform prep.
Convert into the alternate format
Use the tool for fast file conversion when you need readability or portability, not final publishing polish.
Decide whether professional production is needed
If the converted file is heading to KDP, IngramSpark, or another retail platform, use the result as a checkpoint rather than the final deliverable.
Converter
Use the converter for fast format swaps, then decide whether the file is retail-ready.
Conversion is useful for review and internal workflow, but publication-ready files often still need professional formatting and platform-specific checks.
Market notes
Ebook Conversion for US Authors
These notes explain how this market handles ebook and print formats so you know when a quick conversion is enough and when it is not.
US authors publishing through Amazon KDP need both EPUB and PDF formats. KDP accepts EPUB (or DOCX) for Kindle ebooks and PDF for paperback/hardcover interiors. If you've formatted your book as an EPUB and need a quick PDF proof, or vice versa, this converter handles the job instantly.
For KDP paperback submissions, Amazon requires a print-ready PDF with specific settings: PDF/X-1a or PDF/A compliance, embedded fonts, CMYK colour space, and 300 DPI images. Our free converter creates a basic text PDF suitable for proofing and review — for publication-ready PDFs, professional formatting ensures KDP acceptance on the first upload.
IngramSpark (used for wide distribution to Barnes & Noble, bookshops, and libraries) has even stricter PDF requirements than KDP. While our free converter is excellent for quick text conversion and proofing, IngramSpark submissions should use professionally formatted files to avoid rejection.
The US ebook market is dominated by Amazon Kindle (which uses a proprietary format converted from EPUB) and Apple Books (which uses standard EPUB). If you have a PDF manuscript and want to distribute as an ebook, converting PDF to EPUB gives you a starting point — though professional EPUB formatting will produce a significantly better reading experience.
For US authors, both formats are essential: EPUB for Kindle Direct Publishing, Apple Books, Kobo, Barnes & Noble Press, and other ebook retailers; PDF for print-on-demand through KDP Print, IngramSpark, and Lulu. Most successful self-published authors maintain both formats and update them simultaneously.

Quick conversion is useful, but final distribution files still need the right trim, metadata, embedded assets, and platform-specific validation.
