About

About the PNG to PDF Converter

Upload one or more PNG images and get back a single PDF with each image as its own page, in the order you added them — a common way to package screenshots or transparent-background graphics into one document to send or archive. Building the PDF happens entirely on your device.

PNGs keep their transparency inside the PDF, so a logo or diagram with a transparent background sits directly on the white page with no box around it. Screenshots stay pixel-perfect, which makes "Fit to each image" a good choice for turning a set of screenshots into a document that reads like a slideshow.

FAQ

Frequently asked questions

Quick answers to common questions about the PNG to PDF Converter.

How do I convert PNG images to PDF?

Upload your PNG image or images above, in the order you want them as pages, choose a page size, then click Build PDF. The finished file downloads directly from your browser.

Is this PNG to PDF converter free?

Yes. It's free, with no sign-up and no limit on how many images you combine.

What happens to transparency in a PNG when it becomes a PDF page?

Transparency is kept — each image is embedded as a PNG with its alpha channel — and because a PDF page is white, transparent areas simply show as white in any PDF viewer.

Can I combine multiple PNG images into one PDF?

Yes — upload several images at once, and each becomes its own page in the resulting PDF, in the order you added them.

Are my images uploaded to a server?

No. The PDF is built entirely in your browser using a small PDF library loaded from this site — your images never leave your device.

Can I convert a PDF back into PNG images?

Yes — use the dedicated PDF to PNG converter page to extract each page as an image.

Does the PDF keep my PNG's full quality?

Yes. Each PNG is embedded losslessly, so text and sharp edges in screenshots stay as crisp as the original image.

What page sizes and margins can I choose?

Choose Fit to each image, A4, US Letter, Legal, A3 or A5. For the standard sizes you can add up to 50 mm of padding and place each image at the top left, centre or bottom right.

Can I preview the PDF before downloading it?

Yes. The pages are previewed below the options as soon as you add images, and the preview changes as you adjust the page size, padding and position.
