I Built a Free PDF to EPUB Converter (Because Smallpdf Charges for That)

说明与用途

一个完全在浏览器中运行的免费 PDF 转 EPUB 工具，文件不上传服务器，保证隐私且无费用。

问题

Converting a large PDF manuscript to EPUB using online services was costly and posed privacy risks, as free conversions were limited and files were uploaded to third‑party servers.

结果

A fully functional, free, offline PDF‑to‑EPUB converter that preserves metadata and navigation, with no server involvement or subscription fees.

工作流

• 1. Open the single HTML file in a browser.
• 2. Drag & drop or click to browse and upload the PDF.
• 3. Preview page thumbnails and set book metadata (title, author, language).
• 4. Optionally add custom chapter titles per page or use one‑chapter mode.
• 5. Click download to receive a valid EPUB 3 file.
• 6. Open the EPUB in any e‑reader (Calibre, Apple Books, etc.).

证据

Everything happens locally using pdf.js and JSZip. Your files never leave your device.

来源

A valid EPUB 3 file that opens in Calibre, Apple Books, Google Play Books, Kindle Previewer, or any standard e-reader.
