Complete overview of ebookconvert supported input file types

The ebookconvert supported input file types list covers all common ebook and document formats so users can upload EPUB, MOBI, PDF, AZW3, DOCX, HTML, TXT, RTF, ODT, FB2, CBZ/CBR and ZIP archives for batch conversion.

ebookconvert accepts both single-file uploads and zipped collections for batch processing. Files must be DRM-free; encrypted or vendor-locked files (for example, DRM-protected Kindle books) cannot be converted. Typical per-file limits are generous (up to 500 MB per file depending on plan) and large images are automatically optimized during conversion.

For best results, upload original source files with embedded fonts where possible and keep complex layout elements (tables, footnotes) clearly marked. Over 98% of standard ebook uploads convert without layout issues, and thousands of users trust ebookconvert for both single-file and bulk conversions.

Key conversion capabilities for ebookconvert supported input file types

Wide input format coverage

Supports all major ebook and document formats (EPUB, MOBI, PDF, AZW3, DOCX, HTML, TXT, RTF, ODT, FB2, CBZ/CBR) so you can convert from nearly any source.

Batch and ZIP processing

Upload hundreds of files at once via ZIP or folder upload. Apply a single conversion profile to process entire catalogs in one job.

High-fidelity formatting

Preserves chapters, TOC, images, and embedded fonts when possible. Advanced parsing reduces manual cleanup after conversion.

Metadata and cover management

Edit or auto-detect metadata (title, author, ISBN) and replace or extract cover images during conversion for ready-to-publish files.

Fast, secure processing

Conversions complete in minutes for typical files, with files encrypted in transit and deleted automatically after processing for privacy.

Quick compatibility checklist for common input files

If you’re unsure whether your file will convert cleanly, check for DRM, embedded fonts, and image-heavy layouts. Text-based DOCX, HTML, and EPUB files generally convert with the highest fidelity. PDFs convert reliably for reflowable content but may require manual fixes for complex page layouts.

Use ZIP uploads for multi-file projects and set a batch profile to ensure consistent output across a catalog. For best quality, supply the original source (DOCX or EPUB) rather than a scanned PDF when possible.
