What Is the PNG to PDF Converter?

This free tool converts one or more PNG images into a PDF document directly in your browser. No files are uploaded to any server. Choose your page size, orientation, margins, and how images are fitted to each page, then download the resulting PDF instantly.

How to Convert PNG to PDF

  • Upload one or more PNG images by clicking the upload area or dragging and dropping.
  • Reorder images using the up/down arrows to arrange PDF pages.
  • Choose your page size (A4, Letter, Legal, A3, or custom dimensions).
  • Select portrait or landscape orientation.
  • Set margins and choose how images should fit on the page.
  • Click "Convert to PDF" and download your file.

Tips for Best Results

  • Use "Fit to page" for most cases — it preserves your image aspect ratio while maximizing size.
  • "Stretch to fill" is useful for full-bleed images but may distort non-matching aspect ratios.
  • "Original size" is ideal for screenshots or precise-dimension images.
  • Enable the white background option if your PNG has transparency and you want a clean print.
  • Use custom page size when your images have unusual dimensions.

Frequently Asked Questions

How does the PNG to PDF converter work?+
The tool reads your PNG images directly in your browser and uses the jsPDF library to generate a PDF document client-side. Each image is placed on its own page with your chosen page size, orientation, margins, and fit settings. No files are uploaded to any server — everything runs locally in your browser.
Can I combine multiple PNG images into one PDF?+
Yes! You can upload as many PNG images as you like and they will all be combined into a single PDF document. Each image gets its own page. You can reorder the images using the up/down buttons before converting to arrange pages in your preferred order.
Is my data private? Are images uploaded to a server?+
Your images never leave your device. All processing happens entirely in your browser using JavaScript. No images are uploaded, no data is sent to any server, and nothing is stored. This makes it completely safe for sensitive or confidential images.
What page sizes are supported?+
The converter supports A4, Letter, Legal, A3, and custom page sizes. You can also choose between portrait and landscape orientation, and set margins from none to large. The custom size option lets you specify exact width and height in millimeters.
How does the image fit option work?+
There are three fit modes: 'Fit to page' scales the image to fit within the page margins while preserving its aspect ratio. 'Stretch to fill' stretches the image to fill the entire printable area (may distort). 'Original size' places the image at its native resolution, centered on the page.
What happens to transparent areas in my PNG?+
By default, transparent areas are filled with a white background for PDF compatibility. You can toggle the 'White background' option off if you want to preserve transparency, though note that PDF transparency support varies across viewers.
