Why you might need to convert images to PDF
If you have a group of images you need to send as one organized file instead of separate attachments, converting them to PDF puts them in a single document that's easy to open and print on any device. The tool does this in seconds without complex editing software.
How the tool sizes the PDF page for each image
When converting an image into a PDF page, the tool accounts for the image's original aspect ratio (width to height) and places it on a standard page size (like A4) while preserving that ratio without stretching or distorting it. If the image is landscape and the page is portrait, the tool adds white margins above and below so the image stays fully visible, or it can automatically match the page orientation to the image's orientation. Each image becomes its own separate page, and the pages are then combined into a single PDF file in the order you specify.

Practical tips before you start
Before converting your images, keep these points in mind:
- Arrange the images in the order you want them to appear in the final file before starting the conversion.
- If your images have mixed orientations (some landscape, some portrait), keep in mind each one gets its own appropriately sized page.
- Use good-quality images before converting, since the original image quality determines how clear it looks in the PDF.
- If you'll be printing the file later, make sure the page size (A4 or Letter) suits the printer you'll be using.
If the images are large, the tool automatically fits them within the PDF pages, but if you need higher print quality, check the quality settings if available.
