Is the PNG to PDF tool free?

Yes, completely free with no signup required. Convert as many images as you like.

Your files never leave your browser. All processing is done locally using pdf-lib. Nothing is uploaded to any server.

Does converting PNG to PDF lose transparency?

Transparency is kept. The PNG is embedded with its alpha channel and no background is painted behind it, so transparent areas stay transparent in the PDF. Most PDF viewers and printers show the blank page as white, and a viewer with a dark or coloured page background may show that colour through. If you need a specific background colour, add it in an image editor before converting.

How many PNG images can I add?

Up to 20 images per conversion. Each image becomes one page in the output PDF.

What page size options are available?

Choose "Fit to image" to create pages sized exactly to each image, "A4" for standard European documents, or "US Letter" for North American documents.

PNG images are common outputs from screenshots, design tools, and document scanners. Converting them to PDF makes them easier to share, print, and archive — PDF is universally supported and preserves the exact appearance of your images without further quality loss. want2convert's PNG to PDF tool does the conversion entirely in your browser.

Transparency note:The PNG's alpha channel is preserved when it is embedded, and the tool does not paint a background behind it. Transparent areas therefore stay transparent in the PDF; most viewers and printers simply show the blank page as white. If you need a specific background colour, fill the transparency in an image editor before uploading here.

Multiple images: Add up to 20 PNG files and they each become a separate page in one PDF. Drag the thumbnails to set the order before converting. Click × on any thumbnail to exclude it from the output.

Page size:"Fit to image" creates pages that are sized exactly to the image dimensions — perfect for screenshots or design mockups where you want a 1:1 representation. "A4" and "US Letter" scale each image to fill a standard paper size, ideal for printing.

To convert JPG images instead, use JPG to PDF. To go the other direction and extract images from a PDF, use PDF to PNG.
