Frequently asked questions
Is PNG to PDF free?
Yes. It is free with no sign-up, no watermark and no limits.
Are my images uploaded?
No. The conversion runs in your browser, so your images never leave your device.
Is transparency kept?
Yes. Transparent areas of a PNG stay transparent in the PDF; most viewers show them on a white page.
Why is my PDF larger than with JPG?
PNG is a lossless format, so the PDF keeps every pixel. For photos, JPG to PDF usually gives smaller files.
Can I convert screenshots from my phone?
Yes. Add them from your phone's gallery or files; the tool works in mobile browsers too.
