Never leaves your device — it all runs in your browserPNG to PDF turns your PNG images into a single PDF, in your browser, with the transparency preserved. PNG is the lossless format people reach for with logos, diagrams, screenshots and graphics that have transparent backgrounds — and that transparency is exactly what most converters quietly flatten to white. This tool embeds each PNG with its alpha channel intact using pdf-lib, so transparent areas stay transparent in modern PDF viewers (Chrome, Acrobat). Add your PNGs, order them, and download one PDF — no upload, no watermark, no account. A note on viewers: some very old PDF readers don’t render PDF transparency and may show those areas as white; that’s a viewer limitation, not a change to your file.
