- The PDF page is sized to your image, so it prints and previews without cropping or extra borders.
- Anyone can open the PDF in the viewer built into their browser, phone or computer.
What to expect when converting PNG to PDF
- PDFは透過を保存できないため、透明な部分は「設定」で選んだ背景色（既定は白）で塗りつぶされます。
- You get one page per image, with the picture embedded as a high-quality JPEG. To combine several images into one PDF, use the Image to PDF tool.
