PNG to PDF Converter

PNG is the format screenshots, diagrams and exported graphics usually arrive in, and those are exactly the things people need to hand over as documents. A portal that wants a PDF, a colleague who will print your diagram, or a set of screenshots that should read in order are all easier as one PDF than as loose PNG files.

Because a PDF looks and prints the same on every device, it removes the guesswork of whether your screenshot will open on the other end, and it lets you place several PNGs as ordered pages in a single file.

PNG can carry transparency, which a PDF page cannot show as see-through. Transparent areas are placed on a white background when the page is built, the same result you would get on paper. Sharpness holds up well: a PNG screenshot with crisp text stays legible because the image is placed without heavy re-compression.

The trade-off is size, since PNG files are larger than JPGs. If you are combining many PNGs and the PDF needs to be light for email, compress them or export photo-like images as JPG first, while keeping true screenshots as PNG for their sharp edges. As a rough sense of scale, a full-screen PNG screenshot is often a few hundred kilobytes, so a ten-page screenshot PDF can reach several megabytes unless the images are compressed first.

Screenshots and scans often hold information you would not want on someone else’s server: account pages, internal diagrams, personal forms. Here the PDF is put together entirely on your machine: the PNGs are read locally, arranged into pages, and written back as a downloadable PDF, with no upload and no stored copy. A stack of screenshots becomes one document in a single pass, without an account, and nothing lingers once you leave.

When you add several PNGs, each becomes a page, and the order you add them in is the order they appear. Rearrange with the up and down arrows next to each file before exporting. With A4 or US Letter as the page size, match the orientation to the image so a wide screenshot goes landscape and an upright page goes portrait, and choose whether the image fits the page with a margin of 0.5 or 1 inch or fills it edge to edge. These small choices are what make the finished PDF look deliberate rather than cropped or boxed in white. Orientation set to Auto turns each page to match its own screenshot; if you want every page the same way, choose Portrait or Landscape and create the PDF again. The small page preview under the settings shows how the selected image will sit. It takes a moment and saves reprinting later.
