High-Resolution eBook Screenshots Needed

I need a clean set of high-resolution screenshots of my eBook packaged into a single, press-ready PDF. These images will be the backbone of my upcoming marketing materials, so clarity, sharp text, and true-to-color graphics are essential.

You will open the eBook (EPUB or Kindle file; I will supply both) on a desktop reader (recommendations welcome for capturing clear, retina-quality screenshots), capture each page, and deliver them cropped, aligned, and sequenced in one PDF. Please maintain consistent resolution and a clean, professional styling suitable for marketing purposes. Screenshots should be well-framed to ensure readability and easily adaptable for various platforms like web banners, social posts, or print ads.

Required:
- Consistent resolution (300 dpi or higher)
- No compression artifacts or visible UI chrome
- Final output: one PDF + a folder of the original PNGs or TIFFs

Preferred: Suggestions by the freelancer on cleaner export settings or workflows (e.g., Adobe InDesign, Photoshop).

I’m ready to get started right away and can provide quick answers to questions! Let me see a sample page first so we can lock in quality before proceeding with the rest of the book.
