Why Convert PNG to PDF?

PDFs preserve the exact appearance of images across all devices and operating systems without requiring image viewing software.

Converting PNG screenshots, diagrams, or receipts to PDF makes them easier to share professionally, archive reliably, and print with consistent margins.

Frequently Asked Questions

Will my PNG be the full size of the PDF page?
Yes. The converted PDF page is sized to match your image dimensions at 72 DPI by default. The image fills the entire page without margins.
Can I combine multiple PNGs into one PDF?
The browser tool converts one image per PDF. The desktop app merges multiple images into a single multi-page PDF in one step.
Does the PDF preserve PNG transparency?
Transparent areas in PNG are filled with a white background in the PDF since the PDF format requires a solid page background.
What resolution will the PDF be?
The PDF embeds your image at its native pixel dimensions. Print quality depends on the source image resolution: 300 DPI source produces print-ready output.
Is this conversion really free, and is my file private?
Yes. The browser conversion runs entirely on your device using WebAssembly. Files are never uploaded to a server and are discarded from memory when you close the page. There is no file size tracking, no account link to your upload, and no cloud storage.
Do I need to create an account to convert files?
No. The browser converter works without signing in. An optional account is only needed if you want to save favorites, track conversion history, or upgrade to the desktop app with Polar license activation.
How fast is the conversion?
Most browser conversions complete in a few seconds. Large files (over 100 MB) or heavy formats (video, high-page PDFs) take longer depending on your device's CPU and available memory. The desktop app runs significantly faster using native engines.
