Frequently Asked Questions
How do I convert a PNG file to a PDF for free?
The easiest free method depends on your device. On Mac, open the PNG in Preview, then choose File → Export as PDF. On Windows, right-click the PNG, select Print, choose Microsoft Print to PDF, and click Print. On iPhone, long-press the PNG in the Files app and tap Create PDF. For any device, you can also use the free [Scanjet Document Converter](https://scanjet.app/document-converter/) in your browser — no signup required.
Can I convert multiple PNG files into one PDF?
Yes. On Mac, select all PNG files in Preview's sidebar, then export as a single PDF. On Windows, select multiple images, right-click → Print, and choose Microsoft Print to PDF. The Scanjet Document Converter also supports multi-file uploads to combine PNGs into one PDF.
Will converting PNG to PDF reduce image quality?
Not if you use the right tool. PNG is a lossless format, so quality is preserved as long as the converter embeds the PNG directly rather than re-compressing it as JPEG. Mac Preview, Windows Print to PDF, and the Scanjet Document Converter all preserve the original image quality.
How do I convert PNG to PDF on iPhone?
Open the Files app, long-press your PNG file, and tap Create PDF — iOS creates the PDF in the same folder instantly. For multiple PNGs, select them all, tap More (⋯), then Convert to PDF. You can also use the [Scanjet Document Converter](https://scanjet.app/document-converter/) in Safari — no app download needed.
Is there an offline PNG to PDF converter?
Yes — the best offline options are built into your OS. Mac Preview and Windows Print to PDF both work entirely offline, with no data sent anywhere. On iPhone, the Files app Create PDF feature is also offline and private. All three process your files locally on your device.
