How to convert PNG to PDF online and free
Upload your PNG images
Drag and drop one or more PNG images, or click to select them from your computer or mobile device. You can add as many images as you need: there's no limit because everything is processed in your own browser, not on a server.
Arrange the pages as you like
Drag each image within the list to change the order in which they will appear as pages in your final PDF. The first one in the list will be the first page of the resulting document.
Create and download your PDF
Click the "Create PDF" button and in seconds your document will be ready. Download it directly to your device — the process is 100% private and no images leave your computer.
Why convert PNG to PDF on PDFDocks?
Most image-to-PDF converters work by uploading your file to an external server for processing. PDFDocks works differently: the conversion happens with JavaScript, right inside your own browser. Your images never leave your computer or mobile device at any time, there's no upload, no server involved, and the process is virtually instant because it happens on your own machine.
Is it safe to convert PNG to PDF online with PDFDocks?
+
Yes. Unlike most similar tools, your images are never uploaded to a server: the conversion happens directly in your browser with JavaScript, so no image leaves your device or travels across the internet.
Can I convert multiple PNG images into a single PDF?
+
Yes. You can upload as many images as you want and they will be combined into a single PDF document, with one image per page, in the order you choose.
Is the transparency of my PNG preserved when converting to PDF?
+
The PDF format does not support true transparency like PNG does, so transparent areas in your image will display with a white background in the final document. The rest of the quality remains intact.
Is there a limit on file size or number of images?
+
We haven't set any artificial limits. Since the entire process happens in your own browser, you can convert as many images as you need — the only real limit is the available memory on your device.
Do I need to install any program to convert PNG to PDF?
+
No, you don't need to install anything. It works directly from your browser, on both desktop and mobile, with no account required.
Can I change the page order after uploading the images?
+
Yes. Before clicking "Create PDF", you can drag each image in the list to reorder them as you like. The final PDF will respect that exact order.
