How to Use a Kindle PC Converter to Convert AZW to EPUBConverting Kindle AZW files to EPUB lets you read purchased or personal Kindle books on a wider range of apps and devices — for example, Apple Books, Kobo, Google Play Books, and many EPUB-compatible readers. This guide walks through the legal and practical steps for converting AZW to EPUB on a PC, including recommended tools, preparation, conversion steps, troubleshooting, and tips for keeping metadata and formatting intact.
Important legal note
Check copyright and license restrictions before converting. Converting books you do not own or that are protected by Digital Rights Management (DRM) may violate copyright law or the terms of service of ebook vendors. This guide covers general, lawful scenarios such as converting personal files or DRM-free purchases.
What you’ll need
- A Windows PC (steps shown for Windows; many tools also work on macOS with minor changes)
- The AZW file(s) you want to convert (from your Kindle device, Kindle app backups, or DRM-free purchases)
- A Kindle PC converter application — the most widely used is Calibre with appropriate plugins (free)
- (If files are DRM-protected) a DRM removal tool/plugin — note legal and ethical implications before proceeding
- Basic familiarity with installing software and moving files between folders
Recommended tool: Calibre (free, open-source)
Calibre is a powerful ebook manager and converter that supports many formats including AZW and EPUB. It handles metadata, cover editing, library organization, and batch conversions. For DRM-protected files, third-party plugins exist but may be legally restricted in some jurisdictions.
- Download Calibre from the official site and install it.
- Familiarize yourself with Calibre’s interface: Library, Add books, Edit metadata, Convert books.
Preparing your AZW files
- Locate the AZW files:
- From a Kindle device: connect via USB and copy the file from the “documents” folder.
- From the Kindle for PC app: older versions stored files locally; new versions may use the cloud — look for exported files or use the app’s “download for offline use” feature.
- Confirm whether files are DRM-free:
- Try adding the AZW to Calibre and opening it; if Calibre reports an error or refuses conversion, the file likely has DRM.
- Make backups of original files before attempting any conversion or DRM removal.
Installing DRM-related plugins (optional & legally sensitive)
If your AZW files are DRM-protected and you believe you have a legal right to remove DRM (for example, personal backups where allowed), users commonly use third-party plugins such as DeDRM for Calibre. Because laws differ, this guide does not provide plugin download links or step-by-step DRM removal instructions. Proceed only if you are certain it’s lawful where you live.
Step-by-step: Converting AZW to EPUB with Calibre
- Open Calibre.
- Click “Add books” (top-left) and select your AZW files. They’ll appear in your Calibre library.
- (Optional) Select a book and click “Edit metadata” to correct title, author, series, tags, and cover image. Clean metadata improves reading apps’ organization.
- Select the book(s) you want to convert. You can convert multiple files in a batch.
- Click “Convert books” → “Convert individually” or “Bulk convert” (depending on your choice).
- In the conversion window:
- Set “Output format” (top-right) to EPUB.
- Under “Page setup,” choose the appropriate output profile for your target device (e.g., “Default,” “Tablet,” “Phone”).
- Use “Structure detection” and “Heuristic processing” options if you need to clean up chapter detection or fix formatting issues.
- Check “EPUB output” settings for table of contents, font embedding, and EPUB version (3 recommended for modern readers).
- Click “OK” to start conversion. Progress appears at the bottom-right status bar.
- When done, right-click the book and choose “Open containing folder” to find the new .epub file.
Handling common issues
- Poor formatting (weird line breaks, missing images): Try toggling “Heuristic processing,” adjust “Structure detection” settings, or convert in smaller batches. For image problems, ensure the original file includes images and that Calibre’s conversion settings allow embedding.
- Missing chapters or broken table of contents: Use “Edit book” in Calibre to repair HTML/NCX or manually create a TOC, then reconvert.
- Conversion fails or shows errors: Check Calibre’s log (click the status bar icon) for details; try updating Calibre to the latest version.
Preserving metadata and covers
- Always edit metadata before conversion to ensure author, series, and cover are embedded in the EPUB.
- Use “Download cover” in the metadata editor or drag a high-resolution image into the cover area. Proper metadata helps ebook apps sort and display books correctly.
Batch converting many files
- Add all desired AZW files to Calibre. Select them and choose “Convert books” → “Bulk convert.”
- For consistent results across a library, set conversion defaults in Preferences → Conversion. This saves time and ensures uniform output settings.
Alternatives to Calibre
- Online converters (e.g., Zamzar, Convertio): convenient for single, small files but watch privacy and file size limits.
- Dedicated commercial converters: sometimes offer simpler GUIs or DRM handling; check reviews and legal compliance.
- Kindle app export: in some cases you can export or re-download purchases in different formats via vendor services.
After conversion: reading and validating EPUBs
- Open the EPUB in an EPUB reader (Calibre’s ebook viewer, Adobe Digital Editions, Thorium, Apple Books, or any EPUB-capable app) to verify formatting, images, and TOC.
- If the EPUB will be transferred to an e-reader (Kobo, Nook, etc.), use the reader’s recommended import method or Calibre’s “Send to device” feature.
Tips for best results
- Keep Calibre updated.
- Work from DRM-free files when possible.
- Tweak conversion settings for complex books (text-heavy novels vs. illustrated or academic books).
- Maintain a backup of originals; keep a consistent folder structure for source files.
Quick troubleshooting checklist
- File won’t convert → check for DRM.
- Missing images → verify original file contains images and enable image embedding.
- Bad TOC → adjust structure detection or manually edit the TOC.
- Metadata not showing → edit metadata before conversion and embed cover.
Converting AZW to EPUB with Calibre gives you flexibility to read books across many devices. Follow legal guidelines around DRM, prepare and back up your files, and use Calibre’s metadata and conversion options to get clean, portable EPUBs.
