Image-to-PDF Quality and Pages
Sharpness comes from the image pixels, not the PDF page size. A4 suits printing/archiving; image-size pages suit web sharing. Check mixed portrait/landscape pages so photos are not cropped.
A4/Letter for printing and formal documents.
Image size for portfolios/web sharing.
Use 18-24 pt margins to avoid edge crowding.
Upscaling a small image does not add detail.
Prefer PNG for screenshots/text.
Many photos make large PDFs; watch sharing limits.
FAQ
Why is text blurry?
The source resolution is low or over-compressed; use the original.
Can it compress the PDF?
No PDF compression yet; downscale images first.
