A fast, private PNG to PDF converter
Converting images to a standard document format makes them much easier to share, print, and archive. This PNG to PDF converter allows you to take one or more PNG files and instantly turn them into a single, multi-page PDF document. Whether you are compiling a tutorial from screenshots, archiving digital receipts, or preparing design assets for a client presentation, this tool handles the conversion cleanly and efficiently.
Because this tool runs entirely within your web browser, your files are never uploaded to an external server. All processing happens locally on your device's own memory. This means you can safely combine PNG into PDF even if the images contain highly sensitive information, such as bank statements, medical records, or confidential work documents. It also means the conversion is practically instantaneous, as you don't have to wait for large image files to upload or download over your internet connection.
How to combine PNG into PDF effectively
When you convert PNG to PDF, you often need control over how the images are presented on the page. This tool provides several layout options to ensure your final document looks exactly as intended.
Page Size: You can choose standard document sizes like A4 or US Letter, which are perfect if you intend to print the resulting PDF or if it needs to match other standard documents. Alternatively, you can select the "Fit to image" option. This setting calculates the exact dimensions of your PNG and creates a custom PDF page size to match it perfectly, preventing any unwanted white space or awkward scaling.
Orientation: If you select a standard page size like A4, you can force the orientation to Portrait or Landscape. However, the most convenient option is usually "Auto." When set to Auto, the tool examines the dimensions of each individual PNG image. If an image is wider than it is tall, that specific page in the PDF will automatically be set to Landscape, ensuring the image is displayed as large as possible without being distorted.
Margins: Depending on your needs, you can add a small or large margin around your images, or choose no margin at all. A small margin is generally recommended if you plan to print the document, as it prevents the edges of your images from being cut off by the printer.
Ordering: When you upload multiple files, they appear in a grid. You can easily review your selection, remove any unwanted files, and use the arrow buttons to adjust the sequence. The order of the images in the grid will be the exact order of the pages in your final PDF.
Common uses for converting images to PDF
Screenshot to PDF: This is perhaps the most common use case. Both macOS and Windows frequently save screen captures as PNG files. If you are creating a step-by-step software tutorial, documenting a bug for technical support, or saving a thread of messages, you can drag all those screenshots into this tool and generate a single, cohesive document.
Design and Web Assets: Web designers and digital artists frequently work with PNGs because the format supports transparent backgrounds and crisp, lossless graphics. When presenting mockups, logos, or UI elements to a client, bundling them into a single PDF is much more professional than sending a folder full of loose image files.
Scanned Documents: While many modern scanners output directly to PDF, some older models or mobile scanning apps may save individual pages as high-quality PNG images. This tool allows you to take those separate scanned pages and merge them back into a proper, multi-page digital document.
Managing your PDF files
Because the PNG format is lossless—meaning it retains all original image data without compression artifacts—PNG files can be quite large. When you embed several high-resolution PNGs into a PDF, the resulting document will also have a large file size. This is excellent for preserving quality, but it might make the file difficult to send as an email attachment. If your final document is too large, you can easily reduce its size using our Compress PDF tool.
If you are working primarily with photographs rather than screenshots or graphics, you might prefer to use our JPG to PDF tool, as the JPG format is naturally more compressed. Conversely, if you have a PDF document and need to extract its pages back into high-quality image files, you can use the PDF to PNG converter to reverse the process.
