- EPUB is lossless, and PDF can be either. At typical quality settings this lands on lossy and trades size for some quality loss. Keep EPUB as a source if you may need a higher-detail version later.
关于 EPUB 转 PDF 的常见问题
这个 EPUB 转 PDF 转换器是免费的吗？
是的。在这里把 EPUB 转换为 PDF 完全免费，无需账号、没有水印、也没有每日次数限制。处理在你自己的设备上完成，因此不存在需要转嫁给你的服务器成本。
我的 EPUB 文件会被上传到任何地方吗？
For browser-based pairs, your file is read locally and converted by pdf.js in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
EPUB 转 PDF 有文件大小限制吗？
There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.
可以一次把多个 EPUB 文件转换为 PDF 吗？
Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.
EPUB 转 PDF 能在手机、Mac 或 Chromebook 上使用吗？
Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.
Why do some conversions take longer on first run?
The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.
I converted a file and the output is blank or unusable. What should I check?
Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
