Why turn images into a PDF
A PDF is the easiest way to send a set of photos or scans as one file instead of a dozen attachments, such as a signed form photographed page by page, a set of receipts, or product photos for a catalog.
How to convert images to PDF here
Upload your images in the order you want them to appear. Each becomes its own page, full-size, in a new PDF.
If your images vary a lot in size, consider resizing them first (see the image resize tool) so the resulting PDF's pages are consistent.
Combining it with other steps
Describe the whole task to the AI File Agent to chain steps automatically. For example, "resize these images, turn them into a PDF, and add page numbers" runs all three in order without you using three separate tools.
