What kind of artwork can I use?
Choose your own JPG, PNG or WebP drawings. The example contains three original line illustrations. This tool arranges pages; it does not trace photographs, remove backgrounds or generate artwork. Use images you have permission to reproduce.
Will the whole drawing stay visible?
Show the whole image keeps its original proportions and centers it inside the margin. Fill the page crops to that same area. Color and transparency are not removed; transparent backgrounds print white. For crisp black lines, start with a sharp, high-resolution original.
Why are blank pages included?
Blank backs places a completely empty page after each illustration and each front-matter page. Twenty illustrations with no title, copyright or contents pages produce exactly forty PDF pages. Turn off blank backs to place artwork on consecutive sides. The contents list always uses physical PDF page numbers, including front matter and blanks.
