Frequently Asked Questions
PDF 和 PDF/A 有什么区别？▼
PDF/A is a locked-down, ISO-standardized version of PDF built specifically for archiving. It embeds every font and color profile directly in the file, so the document looks the same decades from now, regardless of what software opens it.
转换为 PDF/A 会增加文件大小吗？▼
通常是的，因为 PDF/A 要求所有字体和颜色数据完全独立于文档内，而不是依赖于读者的系统字体。
Who actually needs a PDF/A file?▼
It's most often required for legal filings, government records, medical archives, and academic institutions that mandate long-term, standards-compliant document storage.
转换为 PDF/A 是否会删除密码或加密？▼
Yes — PDF/A doesn't allow encryption, so any password protection is stripped as part of bringing the file into compliance.
Can I open a PDF/A file in a normal PDF reader?▼
是的，PDF/A 文件可以在任何标准 PDF 查看器（如 Adobe Reader 或浏览器）中打开 - 该格式是 PDF 的更严格的子集，而不是单独的文件类型。
