What happens to transparent PNGs
PNG is the one common image format that supports true transparency, so a lot of logos, icons, and graphics have see-through backgrounds. A PDF page, however, has no transparency of its own — it is like a sheet of paper. When a transparent PNG goes into the PDF, those see-through areas simply show as white, which is exactly how the image would look printed on a page. If you need a particular colour or texture behind the image, paint it in before converting. Everything that is actually drawn in the PNG stays perfectly intact.
The best format for screenshots and diagrams
Screenshots, UI mockups, charts, and diagrams are almost always saved as PNG, because PNG keeps hard edges and small text crisp instead of blurring them the way photo compression can. This tool plays to that strength: your PNGs are dropped into the PDF untouched, so a screenshot of a settings screen or a step-by-step guide stays just as readable in the document as it was on your screen. It is the cleanest way to turn a series of captures into a walkthrough, a bug report, or a handover doc.
Your PNGs stay lossless
Unlike formats that have to be re-encoded, PNG files are embedded into the PDF byte-for-byte, with no quality loss whatsoever. Whether you convert one screenshot or fifty pages of scanned line art, every page in the finished PDF is a pixel-exact copy of the image you started with. If the resulting file is larger than you want because of high-resolution captures, run it through Compress PDF afterwards to bring the size down.
Put your pages in order and choose a size
Each PNG you add appears in a list with its name and size. Drag any of them by the grip handle to move it up or down, on desktop or mobile, or use the arrows for single steps — the final PDF follows the list from top to bottom. For the page shape, Fit to image makes every page exactly match its picture, ideal for on-screen viewing, while A4 and Letter center each image on a standard page with a small margin for clean printing.
Is it safe to convert PNGs here?
Yes. Many free image-to-PDF sites upload your pictures to their servers to do the work. This tool does not. Your PNGs are read and combined right inside your browser, so they are never uploaded, stored, or seen by anyone else. That makes it a safe choice for screenshots of private accounts, scanned documents, and anything else you would rather keep off a stranger's server.
Can I convert PNG to PDF on my phone?
Yes. This tool works in any modern browser on iPhone, Android, tablets, and computers, with nothing to install. Add PNGs from your gallery or files, drag them into order, pick a page size, then tap Create PDF and the combined file saves to your device.

FAQs about PNG to PDF
Are my PNG images uploaded anywhere?
No. Your PNGs are read and turned into a PDF inside your browser on your own device. Nothing is sent to any server, so screenshots and documents stay completely private. When you close the tab, nothing is left behind.
Do transparent PNGs keep their transparency?
A PDF page has no transparency of its own, so any see-through areas of a PNG appear on a white background in the finished PDF — exactly how the page would look when printed. If you need a specific colour behind the image, add it before converting.
Will my PNGs lose any quality?
No. PNG files are embedded into the PDF exactly as they are, with no re-compression, so every pixel and every bit of fine text stays as sharp as the original. That lossless handling is what makes PNG so good for screenshots and diagrams.
Can I combine several PNGs into one PDF?
Yes. Add as many PNGs as you like and each becomes one page, in the order you set. Drag them by the grip handle to rearrange, or use the arrows, and remove any with the cross button.
Can I add other image formats too?
Yes. You can mix in JPG, WebP, AVIF, BMP, GIF, TIFF, and SVG alongside your PNGs — see the full JPG to PDF tool, which accepts every common format.
Is each PNG its own page?
Yes. Every image becomes a single page in list order. To place several pictures on one page, arrange them in an image editor first, then convert that combined image here.
Can I choose the page size?
Yes. Fit to image makes each page match its picture exactly, edge to edge. A4 or Letter centers the image on a standard page with a small margin, which is better for printing.
Can I turn a PDF back into PNG images?
Yes. Use our PDF to PNG tool for the reverse — it renders each page of a PDF into a sharp PNG you can download.
Does it work on my phone?
Yes. It runs in any modern browser on iPhone, Android, tablets, and computers, with nothing to install. Add your PNGs, set the order, and the PDF saves straight to your device.
Is PNG to PDF really free?
Yes. It is completely free with no sign-up, no watermark, and no file-size limit. It works the same on phones, tablets, and computers in any modern browser.
