Convert PNG files to PDF free in your browser — no signup, no install, and the file is never uploaded to a server. PDF keeps full quality with no further loss.
Add your PNG file
Drag the PNG file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm PDF as the output
PDF is already selected as the output format on this page. Only the options this format actually supports show up, such as a page range or sheet selection.
Run the conversion
Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.
Download the PDF file
When it finishes, download the PDF file. Converting multiple files gives you the option to download them together as a ZIP.
A lossless image format that preserves quality perfectly and supports transparent backgrounds via an alpha channel. Better suited to logos, icons, and screenshots than photographs.
A document format engineered so that fonts, margins, and layout look identical on any device. Virtually every operating system and browser opens it natively.
Yes. PNG to PDF conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the PNG file never leaves your device. That is also why it works without an internet connection once the page has loaded.
No — PDF has no alpha channel, so transparent pixels are replaced with a solid background. If transparency matters, convert to PNG or WebP instead.
It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
