Bundling PNG images into one PDF
Screenshots, photos or exported graphics become a document in a few steps. What matters is the order, the page size and whether the whole image must stay visible.
Set the order
Each image becomes exactly one page, in the order of the list. Drag an image or use the arrow buttons to move it up or down; the number on the left shows its final page number.
Choose the page size
A4 and US Letter produce a uniform document. Original size instead uses the physical size derived from the resolution stored inside the PNG.
If that value is missing from the image, 96 dpi is assumed. The page can then turn out larger or smaller than expected, which is common with screenshots.
Fit or crop
With fitting, the whole image stays visible and margins may appear. With cropping, the image fills the page but parts of the edges disappear.
For documents containing text, fitting is the safe choice. Cropping suits photos meant to cover a full page. The preview shows which area survives before you export.
Margins and rotation
Margins keep content away from the paper edge, which helps when printing. For borderless presentations they can be switched off.
A photo taken sideways can be rotated by 90 degrees with the rotate control. Rotation affects only the PDF page, not the image file.
Quality and transparency
PNG data is embedded directly into the PDF and is not re-encoded as JPEG. Transparent areas stay transparent. The complete original file with all its metadata is not copied byte for byte into the PDF.
