Convert PNG to PDF
Put screenshots or graphics into one PDF, in order, without losing a pixel.
Runs in your browser. Nothing is uploaded.
Screenshots are the usual case, and they are the case PNG exists for: sharp text, flat colour, hard edges. Embedded into a PDF they stay exactly that, because the pixels are carried across unchanged rather than re-encoded on the way in.
The order is the document, so the pictures are a draggable list with sort by name for the common case. Numeric sorting means screenshot-10 lands after screenshot-9, which alphabetical sorting famously does not.
Fit is the right setting for screenshots: each page takes the size of its own picture, so there are no margins, no letterboxing and nothing to decide. Pick A4 or Letter when the document is going to be printed or attached to something that expects paper, and the pictures are centred with a margin — scaled down where they are too big and left alone where they are not.

Questions
Are transparent areas kept?
The transparency is embedded, and a PDF viewer shows what is behind it — which is the page, so it reads as white. Put a background on the image first if you need a specific colour.
Is anything re-compressed?
No. The PNG is embedded as it arrived, so the document holds exactly the pixels you dropped in.
Why is my PDF so large?
PNG is lossless, and a lossless page of photography is big. If the pictures are photographs rather than screenshots, JPEG makes a far smaller document.
