Check whether EPUB Fixer should stop here.
Use this page when an upload is rejected, a report says Not supported, or the next fix belongs in your source tool, EPUB editor, or KDP settings.
Rejected before scan: DOCX, PDF, KPF, KCB, ZIP, DRM, fixed-layout
Not repaired here: layout, source asset, account, or meaning decisions
Next step: export a reflowable EPUB or fix the source workflow
Decision boundary
Find the stop reason before retrying.
Use the first column when the file should not be uploaded here. Use the second when the EPUB may scan, but the fix needs source tool or publishing judgment.
Rejected before scan
File is not scan-ready.
If the input is not a normal reflowable EPUB package, the scanner cannot inspect the paths, metadata, or EPUBCheck output it needs.
Have a DOCX, PDF, KPF, KCB, or ZIP archive?Matched
Export a real .epub first. This scanner needs container.xml, content.opf, packaged links, images, and EPUBCheck output; source files and generic ZIP archives do not provide the same scan path.
Have a fixed-layout, comic, manga, or picture book?Matched
Use the original design or export tool instead. Automatic structural edits can damage page-by-page layout, image placement, or reading order.
Image-first EPUB structure detected?Matched
This usually means the book is mostly page images with little XHTML text for the scanner to repair. Use the original source/export workflow or another EPUB editor instead.
Have a DRM-protected or encrypted EPUB?Matched
Use the authorized source file or publisher workflow. EPUB Fixer cannot inspect protected package files or remove access controls.
Need OCR cleanup, source image replacement, or a full re-export?Matched
Fix the source project first, then export a new EPUB. The scanner should not invent missing book content, recreate OCR text, or replace images by guesswork.
Not repaired here
Fix needs a source decision.
Go back to your source project, EPUB editor, or KDP workflow when the next step requires layout judgment, manuscript choices, source assets, or account changes.
Need cover, typography, layout, or formatting quality changes?Matched
Fix that in your source tool, design tool, or EPUB editor. EPUB Fixer checks upload-blocking structure errors, not cover design, typography, spacing, or visual quality.
Need to choose chapter meaning, section names, or reading order?Matched
Review the manuscript or source project manually. A scanner should not decide where readers should land or what a chapter should be called.
Need KDP account, pricing, category, tax, or review help?Matched
Handle that inside KDP. Those settings are outside the EPUB file, so the scanner cannot see or repair them.
Missing source files with no safe replacement inside the EPUB?Matched
Restore the original image, stylesheet, chapter, or nav file before scanning again. If there is no clear target, the report should stop at diagnosis.
