Calling all of these a &#8216;file rejection&#8217; hides the fastest route to the fix.<\/p>\n<p>Start by identifying which stage failed and whether the problem belongs to the interior, cover, metadata, or content itself. Then fix the source file rather than repeatedly exporting the same broken version.<\/p>\n<h2 id=\"ebook\">Ebook Problems: Use the Supported Formats and Preview the Conversion<\/h2>\n<p>KDP currently supports several ebook manuscript formats, including DOC\/DOCX, KPF, and EPUB. EPUB must meet Kindle publishing specifications, while Kindle Create can produce KPF and EPUB for supported reflowable workflows. MOBI guidance in old tutorials is increasingly obsolete and should not be your default production route.<\/p>\n<p>If conversion fails, first open the source in its native application, save a fresh copy, and test again in Kindle Previewer. Complex Word formatting, broken styles, unsupported layout techniques, bad image placement, and malformed EPUB structure are common causes of conversion trouble.<\/p>\n<aside class=\"vg-alert vg-alert-amber\">\n<div class=\"vg-kicker\">Use current formats, not old MOBI tutorials<\/div>\n<p>KDP currently supports DOC\/DOCX, KPF, EPUB, and other specified ebook formats. Amazon recommends testing converted ebooks in Kindle Previewer. <a href=\"https:\/\/kdp.amazon.com\/en_US\/help\/topic\/G200634390\" target=\"_blank\" rel=\"noopener\">See supported ebook formats<\/a>.<\/p>\n<\/aside>\n<h2 id=\"toc\">Broken Navigation and TOC Errors<\/h2>\n<p>Kindle books need working logical navigation. Manually typed page-number TOCs, fake headings, stale chapter links, and malformed EPUB navigation can create a book that opens but fails quality review or produces a poor customer experience.<\/p>\n<p>Fix the heading hierarchy and regenerate the navigation from the source. Then test both the Go To menu and any visible HTML TOC in Kindle Previewer before re-uploading.<\/p>\n<h2 id=\"print-file\">Print Interior Errors: Margins, Bleed, Fonts, and Page Geometry<\/h2>\n<p>Print Previewer automatically checks issues such as margins, cover size, and fonts. Bleed is one of the most common causes of print-review problems. If interior elements extend to the page edge, KDP requires the manuscript to be uploaded as PDF with the correct bleed dimensions.<\/p>\n<p>Print Previewer may attempt to scale or reflow some content, but do not rely on automatic correction for a production book. Fix margins, trim size, bleed, and page geometry in the source application, create a fresh PDF, and upload that version.<\/p>\n<aside class=\"vg-alert vg-alert-amber\">\n<div class=\"vg-kicker\">Bleed is a major print failure point<\/div>\n<p>KDP says failure to account for bleed is one of the most common reasons print manuscripts do not pass quality review. Interior bleed requires a PDF upload. <a href=\"https:\/\/kdp.amazon.com\/en_US\/help\/topic\/G202187840\" target=\"_blank\" rel=\"noopener\">See KDP manuscript preparation<\/a>.<\/p>\n<\/aside>\n<h2 id=\"fonts\">Font Errors Can Hide in Places You Cannot See<\/h2>\n<p>KDP can reject print files when fonts cannot be printed successfully. Font problems may sit in visible text, spaces, punctuation, headers, footers, line breaks, or style definitions. Faux bold or faux italic styling can also create failures when the actual font face is missing.<\/p>\n<p>Embed fonts correctly and use font families with real bold and italic variants where the design calls for them. If Previewer identifies a font error, inspect document styles as well as visible pages before exporting again.<\/p>\n<h2 id=\"cover\">Cover File Problems<\/h2>\n<p>Print covers fail when dimensions, spine width, bleed, barcode area, image quality, or fonts do not match the final book specifications. The full wraparound depends on trim size, page count, paper, and format, so a cover built before the interior is final can become wrong even without a design change.<\/p>\n<p>Use KDP&#8217;s Cover Calculator\/template for the final specification and export a new cover from the original design file. Do not stretch an old PDF to fit a new spine width.<\/p>\n<h2 id=\"quality\">Files Can Pass Upload and Still Fail Quality Review<\/h2>\n<p>KDP&#8217;s Kindle quality guidance includes typos, blurry images, unsupported formatting, inline page numbering, forced text colors, unreadable scans, and wrong content among the issues that can trigger action. A technically valid file is not automatically a high-quality ebook.<\/p>\n<p>Wrong-content problems are particularly serious because the customer receives something different from what the listing promises. Before every upload, open the exact file and confirm title, edition, front matter, manuscript version, and cover belong together.<\/p>\n<h2 id=\"content\">Some &#8216;File&#8217; Problems Are Actually Content or Metadata Problems<\/h2>\n<p>A manuscript can be structurally perfect and still be rejected because of rights, misleading metadata, prohibited content, public-domain rules, AI disclosure, or a product that is unsuitable for Kindle reading. Do not keep rebuilding the PDF when Amazon&#8217;s message points to a content-policy issue.<\/p>\n<p>Read the notification literally and follow the linked policy. If the reason remains unclear, contact KDP support with the exact message and title details rather than guessing which technical setting caused it.<\/p>\n<h2 id=\"workflow\">A Faster Rejection-Repair Workflow<\/h2>\n<p>Save the rejection message, identify the affected format, reproduce the problem in Previewer where possible, and return to the source project. Fix one category of error at a time and name the new export clearly so you do not upload yesterday&#8217;s rejected file again.<\/p>\n<p>After the fix, run the entire preview rather than checking only the reported page. Margin, style, font, or conversion errors often repeat throughout a manuscript even when the tool shows one example.<\/p>\n<h2 id=\"messages\">Read the Rejection Message for the Noun, Not the Tone<\/h2>\n<p>KDP notifications can sound generic, but the important words usually identify the layer: margin, bleed, font, cover, metadata, rights, quality, navigation, wrong content, or unsupported formatting. Copy the exact wording into your repair notes before changing anything.<\/p>\n<p>If the message includes page numbers, inspect those pages and several nearby examples. A single flagged page can be the first place an automated check detected a document-wide style or margin problem.<\/p>\n<h2 id=\"versioning\">Version Control Prevents Repeat Rejections<\/h2>\n<p>Many resubmission failures are versioning failures rather than formatting failures. The author fixes the manuscript, exports a new PDF, then uploads the old file from Downloads because both are called final.pdf. The technical problem was solved, but the rejected file returned.<\/p>\n<p>Use deliberate filenames such as book-title-print-v7-bleed-fixed.pdf and archive superseded versions. Keep the editable source, exported file, cover, and upload notes together so the next update begins from the known published version.<\/p>\n<div class=\"vg-checklist-box\">\n<div class=\"vg-kicker\">Before resubmitting<\/div>\n<h3>A five-minute rejection check<\/h3>\n<ul>\n<li>Confirm you edited the source file that produced the rejected upload<\/li>\n<li>Export to a new clearly named file<\/li>\n<li>Open that exact file from start to finish<\/li>\n<li>Run Kindle Previewer or Print Previewer as appropriate<\/li>\n<li>Check the cover against the final interior page count<\/li>\n<li>Upload the new file and keep the rejection message until the title is approved<\/li>\n<\/ul>\n<\/div>\n<h2 id=\"faq\">Frequently Asked Questions<\/h2>\n<div class=\"vg-faq-list\">\n<details class=\"vg-faq\">\n<summary>What ebook file types does KDP accept?<\/summary>\n<div class=\"vg-faq-answer\">\n<p>KDP currently supports multiple formats including DOC\/DOCX, KPF, and EPUB.
