How do I convert multiple JPG files to one PDF?
Import the whole batch of JPG photos at once, then open "Convert Format" and pick PDF. Every JPG becomes its own page in a single PDF file, in the order they appear in your batch — there's no need to convert each photo separately.
Can I reorder or edit the JPGs before they become PDF pages?
Yes — crop, resize, rotate, compress, and watermark all run first, in the same batch pass, and the PDF is built from the already-processed images. Reorder the images in the thumbnail strip before processing if you need a specific page order — there's no separate reordering step after the PDF is generated.
Will the PDF be a huge file if my JPGs are full-resolution phone photos?
It can be, since each image is embedded at full resolution. Compressing the JPGs first (or resizing to a sensible width) in the same batch pass usually keeps the resulting PDF a reasonable size without a visible quality loss.
