将 PDF 转成 EPUB

什么是 PDF？

PDF is the world's most widely used document format, developed by Adobe in 1993. It preserves exact layouts, fonts, and graphics across every platform. However, PDFs use fixed layouts that don't reflow on small screens — text stays the same size regardless of the device, making long-form reading uncomfortable on phones and e-readers.

为什么将 PDF 转成 EPUB？

Converting PDF to EPUB unlocks reflowable text: the content adapts to any screen size, you can adjust font sizes, switch to dark mode, and use your reader's built-in dictionary. Ideal for books, long articles, and reports you want to read on Kindle, Kobo, or Apple Books.

PDF 转换技巧

• Text-based PDFs convert cleanly. Scanned PDFs (image-only) may produce poor results — use OCR first for best quality.
• Complex multi-column layouts may reflow differently. Simple single-column documents convert best.
• Charts and diagrams are preserved as images.

为什么选择 EPUB？

EPUB 是由 W3C 维护的数字书籍开放标准。与专有格式不同，EPUB 可在 Kindle、Kobo、Apple Books、Google Play Books 及数百款第三方应用上使用。文字可自动适应任意屏幕尺寸，字体大小可调节，还支持文字转语音、护眼字体等无障碍功能。
