How to Convert PNG to PDF
Select your PNG images
Click the upload area or drop one or more PNG files — screenshots, graphics or scans.
Pages are assembled locally
Each PNG becomes a PDF page matched to its dimensions, built entirely in your browser.
Download the PDF
Save a single document with every image as its own page.
The image is embedded, not converted
The picture is placed into a PDF page rather than re-encoded, so nothing is lost in the conversion. What changes is the wrapper: a file that opens in an image viewer becomes a document that opens identically on every device and can be printed, signed and filed.
PNG's transparency has no equivalent in a printed page, so transparent areas are rendered against white. A logo with a transparent background becomes a logo on a white page, which is almost always what is wanted here.
Pixels, page size and print quality
A PDF page is measured in points; an image has pixels but no physical size. Placing one on the other requires choosing a scale, and that choice decides print quality. A 2480-pixel-wide image on an A4 page prints at about 300 dpi and looks sharp; a 600-pixel screenshot on the same page prints at around 70 dpi and looks soft.
This is why a document that looks perfect on screen can disappoint on paper. If the result is destined for a printer, start from the largest version of the image you have.
Several images, one document
Each image becomes a page, in the order you arrange them. A set of scanned receipts, photographed contract pages or exported screenshots becomes a single ordered file instead of a folder someone has to piece together.
That is the main reason this conversion exists. A recipient with many documents to process can lose one image out of ten; they cannot lose one page out of a PDF.
Size, and when to compress
Because images are embedded rather than recompressed, the PDF is roughly the sum of the source files. PNG is a large format for photographic content, so a document built from ten photographic PNGs will be substantial.
The right fix is to resize or convert the images before building the PDF, not to compress the PDF afterwards — compressing a PDF rasterises the pages and costs quality that the conversion itself did not.
Margins, orientation and privacy
Matching page orientation to image orientation avoids wasted space, and leaving a small margin is safer for printing, since many desktop printers cannot print to the paper edge and will scale or crop the page instead.
Everything happens in your browser. Screenshots of internal systems, photographs of identity documents and scanned forms are the usual input here, and none of it leaves your device.
Why a form asks for PDF instead of images
Institutions ask for PDFs because a PDF is one file with a fixed page order that opens identically everywhere. Loose images arrive in whatever order the mail client decides, open in whatever application the recipient happens to have, and are easy to separate from each other by accident.
There is a practical consequence for you as well: a submission rejected for the wrong format costs a round trip and sometimes a deadline. Converting first takes a few seconds; resubmitting can take days.
