常见问题

FAQ

转换后的PNG图片能用于打印吗?

可以。PDFnoted 默认输出300dpi PNG,符合专业印刷要求;建议使用A4尺寸PDF源文件,以确保单页PNG在打印时保持1:1比例和清晰度。

支持中文PDF和复杂字体吗?

完全支持。PDFnoted 基于原生PDF渲染引擎,保留所有嵌入字体(含思源黑体、Noto Sans CJK等),中文符号、数学公式、表格边框均无缺失或乱码。

转换过程是否上传到服务器?数据安全吗?

PDFnoted 采用客户端优先处理:90%操作在浏览器内完成;仅必要元数据(如页数)短暂传输;文件上传后1小时内自动删除,不存储、不分享、不留痕。

Are the exported PNGs print-ready?

Yes. PDFnoted exports at 300dpi by default — suitable for professional printing. For best results, use A4-sized source PDFs to maintain 1:1 scale and clarity.

Does it support Chinese PDFs with embedded fonts?

Fully supported. PDFnoted uses native PDF rendering — preserves embedded fonts (e.g., Noto Sans CJK), Chinese glyphs, math formulas, and table borders without corruption or missing characters.

Is my PDF uploaded to a server? Is it secure?

PDFnoted prioritizes client-side processing: 90% runs in-browser. Only minimal metadata (e.g., page count) is briefly transmitted. Uploaded files auto-delete within 1 hour — never stored, shared, or logged.
