PNG screenshots into one PDF
Drop PNG files only. Each picture is one page in card order. pdf-lib embeds lossless Flate pixels unless optional PDF compression is on.
Transparency with compression off
RGBA PNGs keep alpha as a soft mask. Optional compression can shrink the file but JPEG pages may drop clear pixels. Leave it off for UI captures.
JPG and WebP go elsewhere
This page is PNG only. Bild in PDF takes JPG and PNG. JPG in PDF takes mixed batches including WebP.
