Why Does Smashwords Reject Ebooks?

1. Meatgrinder DOCX formatting requirements

Meatgrinder requires Word documents that conform strictly to the Smashwords Style Guide. The auto-vetter blocks conversion when it detects: tracked changes (Accept All Changes before submitting), Word comments, field codes (which produce auto-generated TOCs, page numbers, or cross-references in Word), or section breaks. These elements appear invisible in the finished document but cause conversion errors Meatgrinder can't recover from. Smashwords calls the full manual cleanup process the 'Nuclear Option' — a complete style reset in Word before submission.

2. Table of contents format not recognized by the auto-vetter

Smashwords requires a specific manually built table of contents using Word bookmarks — not Word's built-in Insert → Table of Contents feature. A TOC generated with Word's auto-TOC function contains field codes that the auto-vetter flags as conversion-blocking. The correct method (per the Smashwords Style Guide) is a manually typed TOC with each chapter title hyperlinked to a named bookmark at the start of that chapter.

3. Premium Catalog gate: accepted to the store ≠ distributed to retailers

Uploading successfully to Smashwords does not guarantee inclusion in the Premium Catalog, which controls distribution to Barnes & Noble, OverDrive, Scribd, and other retail partners. Premium rejection reasons include: missing or invalid ISBN, cover image under 1400px on the short side, non-standard metadata, and content flags specific to individual retailer partners. Books accepted to the Smashwords store but blocked from Premium appear on Smashwords.com only — no retailer listings appear.

4. Adult content distribution controls

Smashwords allows explicit sexual content on its own store but withholds distribution to Apple Books, Barnes & Noble, and library channels for books marked adult. Authors who mark their book as adult and expect full retail distribution are often surprised to find it blocked from the majority of distribution partners. Smashwords provides a per-retailer opt-in checklist for adult titles in the account dashboard, but the behavior at individual retailers changes when partners update their content policies.

5. D2D merger transition: dual-submission ISBN conflicts

Since Smashwords merged with Draft2Digital (2022), authors who previously used both platforms have had books submitted through both the legacy Smashwords system and D2D's system simultaneously. Retailers receive duplicate deliveries under the same ISBN. Smashwords (sharing infrastructure with D2D) blocks one version — typically the lower-priority submission — without clearly notifying the author. Resolving this requires identifying which system holds the active ISBN and withdrawing from the other.

Can I submit an EPUB to Smashwords instead of a DOCX?

Yes — since the D2D merger, Smashwords accepts EPUB submissions, which bypass the Meatgrinder pipeline entirely. EPUBs go through a lighter processing path. However, you still need to meet all Premium Catalog requirements (ISBN, cover size, metadata) when submitting EPUB, and the EPUB must pass Smashwords' basic validation.

What's the 'Nuclear Option' in the Smashwords Style Guide?

It's a manual formatting reset for Word documents — select all text, clear all formatting, then reapply styles from scratch. The goal is to eliminate hidden formatting artifacts (field codes, embedded styles, autoformatting) that Meatgrinder can't process. The Style Guide walks through the exact steps required.

How is Smashwords different from Draft2Digital now that they have merged?

Smashwords operates as a distinct brand with its own storefront (Smashwords.com) and the Meatgrinder DOCX pipeline. D2D operates as the distribution network backend that both platforms share. From a submission standpoint, they remain separate dashboards with different interfaces and different requirements — but their retail distribution network is now the same infrastructure.
