The playbook

  1. 1

    Download Calibre (Free, Open-Source)

    Go to calibre-ebook.com → Download. Choose your OS (Windows, Mac, Linux). Install normally. Calibre is free and trusted by millions.

  2. 2

    Launch Calibre and Create a Library

    Open Calibre. Choose a location for your library (~/Documents/Calibre Library recommended). This becomes your conversion workspace.

  3. 3

    Add Books to Calibre

    Click 'Add Books' (top left) → Select your PDF, MOBI, HTML, or other ebook files from your computer. Calibre imports them.

  4. 4

    Select Books to Convert

    In Calibre's library view, select the books you want to convert to EPUB. Click multiple to batch-convert (Ctrl+Click or Shift+Click).

  5. 5

    Convert to EPUB

    Right-click selected books → 'Convert Books' → 'Convert Individually'. A dialog opens. Leave format as EPUB. Click OK. Calibre converts all selected books.

  6. 6

    Find Converted EPUBs

    After conversion, right-click a book → 'Open Containing Folder'. This shows where Calibre saved the EPUB file. Copy it to ~/Downloads or organized folder.

  7. 7

    Batch Export to Single Folder

    Optional: Select all converted books → Right-click → 'Save To Disk'. Choose a destination folder (~/Downloads/epubs-for-morph). This copies all EPUBs in one place.

  8. 8

    Open Morph and Import

    On your device: Open Morph app → Library → '+' button → 'Import from Files'. Select your EPUB files. Morph syncs them to cloud.

  9. 9

    Verify Import and Quality

    Open each imported book in Morph. Check formatting (text wrapping, images). If formatting is broken, re-convert in Calibre with different settings.

  10. 10

    Enable TTS on Imported Books

    Open a book → Speaker icon → Select TTS voice and speed. Test. Your Calibre-converted ebooks now have narration in Morph.

Common mistakes

✗Not selecting the right input format in Calibre (it usually auto-detects, but double-check)

→Calibre detects file type automatically. Verify the book is recognized correctly before converting.

✗Converting PDFs with scanned images (no text layer) → Results in gibberish

→Scanned PDFs need OCR (optical character recognition). Calibre has OCR plugin (requires setup). For scanned books, use Google Drive OCR first, or accept imperfect conversion.

✗Not checking EPUB quality after conversion—importing broken formatting to Morph

→Open each converted EPUB in an ebook viewer (Apple Books, Calibre) before importing to Morph. Verify text and images are correct.

✗Converting hundreds of books without testing first

→Convert 1-2 test books first. Verify quality. Then batch-convert the rest.

✗Deleting PDFs after Calibre conversion—losing originals if conversion fails

→Keep original files. If EPUB conversion has issues, you can retry with different settings.
