What This Error Means in Plain English

On KDP's 70% royalty tier, Amazon deducts $0.15 per megabyte from every book sold. If your EPUB is 14 MB because of uncompressed PNGs or print-resolution JPEGs, Amazon takes $2.10 on every single sale. An author selling 500 copies loses over $1,000 per month.

Why Retailers & EAA Regulations Block This File

Amazon does not reject the book, but silently cuts your royalty payout dramatically on every sale.

Technical Specification: Amazon KDP calculates the delivery fee based on total package byte size: ceil(SizeMB) * $0.15. Uncompressed covers, interior banners, and ornaments frequently inflate files by 500% to 1000%.

Manual Fix Instructions (for Sigil / Calibre)

  1. Extract all images from your EPUB's OEBPS/images directory.
  2. Downsample images from 300+ DPI to 150 DPI and convert uncompressed 24-bit PNGs to 82% quality JPEG.
  3. Replace the images in the EPUB archive and verify image links remain intact.
