How can I optimize the file size of an assembled PDF?

Before assembling images into a PDF, convert high-res photos to high-quality WebP or optimized JPEGs using OmniConvert to cut overall payload by ~60%.

How does the tool determine page sequence during image conversion?

Files are sequenced alphabetically by filename (e.g., page_01.png, page_02.png). Prefix filenames with sequential numbers for deterministic order.
