[Full article →](https://blog.pixelmelt.dev/kindle-web-drm/)
**HN Popularity:** 1541 points | 472 comments | 1 day ago
[HN Discussion →](https://news.ycombinator.com/item?id=45610226)
### Summary
The author purchased a Kindle e-book, but the Android app repeatedly crashed and disallowed **offline reading/export**. They discovered that Kindle Web Reader delivers text via **SVG glyph IDs**, not actual text.
**Challenges encountered:**
- Mapping tables change every 5 pages
- Fake movement commands inserted to break automation
- Four font variations + ligatures like `ff` and `fi`
- OCR attempts failed
**Solution:**
- Render each SVG glyph as a 512×512 pixel image
- Use **perceptual hashing & SSIM** to match glyphs with real Bookerly TTF font
- Rebuild an EPUB with styles, hyperlinks, and full layout
**Outcome:**
Decoded **920 pages** (~5.6M characters) and preserved original formatting.
Emphasized **personal backup rights**, not piracy.
### HN Key Points
- DIY cracking teaches more than it saves time/money
- Jailbreaking Kindle + KOReader enables wireless Calibre sync
- Amazon’s DRM has tightened; DeDRM tools are no longer updated
- OCR conversion loses emphasis, indentation, tables, etc.
- Adobe Acrobat’s OCR is superior to simpler tools
