Transparent PNG to PDF
Short answer
You can convert a transparent PNG to PDF here, but PDF pages are not transparent, so transparent areas flatten onto white. It runs with no upload.
Choose PNG images to convert to PDF
or drop your file here.
Add one or more PNG (or JPG) images
Runs in your browser — your file is never uploaded.
This is expected behavior for every PNG-to-PDF tool — PDF has no page-level alpha channel, so transparency becomes white. If you need to keep transparency, a PDF isn't the right container; keep the PNG or use a format that supports alpha.
For logos or graphics you just want to share or print, flattening to white is usually exactly what you want.
How to convert a transparent PNG to PDF
- 1Add the PNG. Transparent areas will render white.
