Basic Knowledge
What is a PDF File
PDF (Portable Document Format) is a document format developed by Adobe. It preserves the original format of documents (including fonts, images, and layout) and displays consistently across different operating systems and devices.
Conversion Advantages
Converting images to PDF makes document management and sharing easier, maintains high image quality, supports cross-platform viewing, is suitable for creating electronic documents, e-books, reports, and provides better document protection features.
Page Settings Explanation
Common page sizes include A4 (210×297mm), Letter (216×279mm), Legal (216×356mm), etc. Choosing the appropriate page size can better display image content.
Portrait is suitable for regular documents, while Landscape is suitable for widescreen images. Choosing the appropriate orientation based on the image's aspect ratio can avoid unnecessary white space.
