Free PNG to PDF – how it works
PNG to PDF converts one or more PNG images into a multi-page PDF directly inside your browser. PNG is the standard format for screenshots, diagrams, design exports, and graphics with transparency — and PDF is the document format accepted by email attachments, portals, and printers everywhere.
The tool uses the same browser-based PDF assembly pipeline as JPG to PDF. Your PNG files are read locally, decoded by native browser APIs, composited against white (for transparent areas), and written into a PDF that downloads immediately. Nothing is uploaded.
If you need to convert a mix of PNGs and JPEGs in one document, use the Images to PDF tool, which accepts any combination of image formats.
Supported formats
- PNG
How to use PNG to PDF online
- Upload your PNG files. Drag PNG images into the upload area or click to browse. Add multiple files to combine them into a multi-page PDF.
- Choose the page layout. Select image-sized pages to match each PNG's exact dimensions, or A4 portrait to fit every image proportionally on a standard page.
- Download the PDF. Click Convert to generate the PDF locally, then download and review it.
When to use it
- Convert a sequence of UI screenshots into a design review PDF to share with stakeholders.
- Package infographics or diagrams exported from Figma, Canva, or Photoshop into a PDF.
- Turn scanned PNG images of signed documents into a single PDF for submission.
- Bundle transparent-background icons or logos into a PDF asset sheet.
Known limitations
- Transparent PNG areas are composited against white — the PDF format does not natively preserve alpha channels in raster images.
- The resulting PDF is image-only and not searchable. Add text using the Add Text to PDF tool after conversion if needed.
- Very large, high-resolution PNGs can exceed browser memory on mobile devices.
Frequently asked questions
Is PNG to PDF completely free?
Yes. Free with no usage caps, no sign-up, and no watermark. The output PDF is clean and unbranded.
Are my PNG files uploaded to a server?
No. The conversion runs entirely in your browser. Your PNG files are never transmitted anywhere.
Does transparent background become white in the PDF?
Yes. PDF raster images do not support transparency, so transparent pixels are filled with white during conversion.
Can I mix PNG and JPG in the same PDF?
For mixed formats, use the Images to PDF tool, which accepts JPG, PNG, and WebP together.
