About PNG to PDF

PNG to PDF is a dedicated online converter for turning PNG image files into PDF documents. Whether you have screenshots, design mockups, diagrams, maps, or illustrations saved as PNG, this tool lets you quickly convert them to PDF format.

The tool offers a fit-to-image mode that preserves the original dimensions, plus A4 and Letter page-size modes that automatically scale images to fit standard paper sizes. Add custom margins around each image, and choose a background color for transparent PNG areas to create a solid background. Use the rotation option to automatically turn landscape images to portrait orientation (90°, 180°, or 270°).

Drop multiple PNG files at once and the tool generates a multi-page PDF in the order you selected. Advanced compression quality settings let you balance file size with image quality for optimal output. All processing runs entirely inside your browser, so no images are ever uploaded to an external server. This makes it safe for confidential documents, internal screenshots, or any sensitive material. Unlike generic image-to-PDF converters, this tool is purpose-built for the PNG format, preserving transparency information when embedding images into the PDF.

How to use PNG to PDF

Drag and drop your PNG images or click to select them (multiple files supported).
Choose a page size (Fit to Image / A4 / Letter), set margins, and select rotation if needed. Optionally pick a fill color for transparent areas.
For advanced control, expand Advanced Options and adjust compression quality with the slider for your preferred balance of file size and quality.
Click the Convert to PDF button to generate and download the PDF.
