What does this PNG to PDF converter do?
It packs one or more PNG images into a single PDF, one image per page, in the order you set. PNG is a lossless format, and this converter keeps it that way: the original image data is embedded directly into the PDF without recompression, so screenshots stay pixel-sharp and graphics keep their crisp edges. Transparency is preserved too — transparent regions simply show the white page behind them.
How to convert PNG to PDF
- Drop your PNG files onto the upload box, or click it to browse.
- Reorder the previews with the arrows until the pages are in the right sequence.
- Pick a page size — "Same as image" hugs each image exactly, A4 or Letter centers it on a standard page — and add a margin if you want breathing room.
- Click convert, then download your PDF.
Why PNG specifically?
PNG is the natural format for anything captured or drawn on a screen: screenshots, app mockups, charts, diagrams, receipts from web checkouts, and graphics with text in them. Those images suffer visibly when they're run through JPG compression. Converting them to PDF without touching the pixels gives you a document that scrolls and prints cleanly, is easy to attach, and can't be accidentally edited like a loose image file.
Runs entirely on your device
The converter is JavaScript running in this page. Your PNGs are read locally, embedded locally, and the finished PDF is saved straight from your browser's memory to your Downloads folder. Nothing is uploaded — a real difference from converter sites that pass your screenshots (which often contain names, emails and account numbers) through their servers.
Tips
- Screenshots of documents look best with "Same as image" and no margin.
- Building a printable handout? Use A4 or Letter with a small margin so nothing sits at the paper's edge.
- Very large PNGs make large PDFs — if size matters more than perfect fidelity, convert the images to JPG first, then use the JPG to PDF tool.
