How do I convert a PNG to PDF?
Add your PNG files to the converter, set the page size and margin, then convert and download. PNG data is embedded into the PDF without re-encoding, so screenshots, diagrams, and line art stay pixel-exact. Up to 20 images can be combined into a single multi-page PDF, in the order you arrange them, entirely inside your browser.

Is converting PNG to PDF lossless?
Yes. PNG uses lossless compression, and this converter embeds the PNG image data directly into the PDF rather than redrawing it through a JPEG pass. That is why there is no quality slider on this page and why there is one on the JPG and HEIC converters. For screenshots of text, UI mockups, charts, and anything with hard edges or flat colour, PNG to PDF is the conversion that keeps every pixel intact.
What happens to PNG transparency in the PDF?
The alpha channel is carried into the PDF, so a logo with a transparent background stays transparent rather than gaining a white box. How that looks depends on the viewer: most modern PDF readers composite transparency correctly, but some older print pipelines flatten it unpredictably. If the PDF is going to a printer, flatten the PNG onto a white background in your image editor before converting so what you see is what gets inked.
Can you combine screenshots into one ordered PDF?
Yes, and the order is yours to set. Add up to 20 PNG files, drag them into sequence in the file list, keep "combine all files into one PDF" enabled, and each image becomes one page in that exact order. This is the fastest way to turn a sequence of screenshots into a walkthrough, a support ticket attachment, or a project handoff document without opening a word processor.
Are my files uploaded when converting PNG to PDF?
No. PNG to PDF conversion is pure client-side work: your browser reads the bytes from disk, pdf-lib assembles the document in memory, and the result is handed back to you as a download. Nothing crosses the network, which means the tool also works with the page already loaded and your connection switched off — a useful test if you want to confirm the claim rather than trust it.
