关于 可搜索 PDF 的常见问题
What is a searchable PDF?
A searchable PDF (often called a sandwich PDF) keeps the original photographed document visible to the eye, but places an invisible machine-readable text layer behind it so you can search and copy words.
Can I search keywords on my computer after transferring the file?
Yes! The resulting PDF is standard-compliant and works with desktop search tools like Windows Search, macOS Spotlight, and Adobe Acrobat Ctrl+F.
