Bài viết này có sẵn bằng tiếng Anh. Giao diện được dịch sang Tiếng Việt.

Converting images to PDF is common for creating documents, portfolios, and archival copies. Here's how to do it right.

Page Size Selection

  • A4 (210×297mm): International standard, most common
  • Letter (8.5×11"): US standard
  • A3 (297×420mm): Large format printing

    • Orientation Tips

  • Portrait: Best for vertical images, documents, and text pages
  • Landscape: Best for horizontal images and presentations

    • Margin Settings

  • No margin: Full-bleed images
  • 10-15mm: Standard document margins
  • 20-25mm: Book-style margins for printing

    • Image Quality Considerations

  • Use PNG for documents with text (lossless quality)
  • Use JPEG for photo albums (smaller file size)
  • Ensure sufficient resolution for printing (300 DPI)

    • Convert images to PDF instantly with our Image to PDF tool — supports multi-page documents with custom layouts.

    Large source photos? Run them through our Image Compressor first to keep the final PDF small without sacrificing visual quality.
