PNG to PDF Online Free — PrivaTools

TL;DR: Upload your file, click PNG, and download the result — free, browser-based, no sign-up, no watermarks. Files are processed and discarded immediately.

Convert PNG to PDF online for free — turn PNG screenshots and graphics into a single PDF with full transparency support. Drag, drop, reorder. No watermarks.

PNG to PDF is part of PrivaTools — a free, open-source alternative to iLovePDF, Smallpdf, and Adobe. Server-side tools process your file in an isolated container and discard it immediately; many tools never upload at all and run entirely in your browser.

How to PNG to PDF with PrivaTools

  1. Upload PNG images — Drop one or many .png files up to 500 MB total.
  2. Choose page size — Letter or A4. Transparency in PNGs renders against a white page background.
  3. Download the PDF — All images become a single PDF, one per page. Lossless — PNG pixels map directly to PDF image objects.

Frequently Asked Questions

Will the PDF be larger than the PNGs?

Roughly the same — PNGs are already losslessly compressed, and PDF embeds them with minimal overhead.

How is transparency handled?

Transparent PNGs render over a white background. If you need true alpha through, use the Image to PDF generic tool with the keep-alpha option.

Is there a max number of images?

Practical limit is around 100 images per conversion before browser upload time becomes inconvenient. Backend limit is 500 MB total.
