PNG to PDF Converter Online Free

Why convert PNG to PDF?

PNG images are ideal for screenshots, graphics, and transparent designs, but they're not always convenient to share as separate files. Converting one or more PNG images into a single PDF makes documents easier to print, email, archive, and keep organized.

PDFly combines PNG images into a PDF directly in your browser, so your files never leave your device — no account, no watermark, nothing to install.

Common uses

Combine PNG images
Save screenshots as PDF
Create printable documents

Share design mockups

Best Practices & Limitations

Tips for best results

Arrange images in reading order before converting, since the tool order becomes the page order.
Use this for screenshots, diagrams, or scanned pages saved as PNG that need to become one shareable document.
Compress the resulting PDF afterward if combining many high-resolution PNGs.

Limitations & when not to use this tool

Each PNG becomes a full page — there's no automatic multi-image-per-page grid layout.
PNG transparency isn't preserved as transparency in the PDF; it typically renders against a white background.
Text within the images isn't searchable unless you run OCR PDF afterward.

Frequently asked questions

Can I merge multiple PNG files into one PDF?

Yes. Upload multiple PNG images, arrange them in the order you want, and create a single PDF document.

Will transparent backgrounds stay transparent?

PDF files don't always preserve PNG transparency the same way image formats do. Transparent areas may appear with a solid background depending on the PDF rendering.

Will the image quality change?

PDFly preserves the original image quality as much as possible. The final result depends on the resolution of the uploaded PNG files.

Can I convert PNG files from my phone?

Yes. The tool works in modern mobile browsers on Android, iPhone, and iPad, allowing you to create PDFs without installing an app.
