PNG to PDF
Convert PNG images into one PDF document. Runs in your browser — nothing is uploaded.
Files are processed on your device and never uploaded
PNG is what screens produce. Screenshots, exported diagrams, charts from a spreadsheet, mockups out of a design tool — they all arrive as PNG, and none of them are convenient to send to someone who wants a document. This tool writes them into a single PDF, one image per page, in whatever order you put them.
Because PNG is a lossless format, the conversion is lossless too. The image is stored inside the PDF unchanged: text in a screenshot stays as crisp as it was on screen, and thin lines in a diagram do not acquire the smeared edges that come from re-compressing to JPEG.
How to convert PNG to PDF
Add your PNG images
Drop them onto the page or click to browse. Several at once is fine, and you can keep adding more.
Arrange them
Move images up or down with the arrows. The document follows the list from top to bottom.
Check the preview
A thumbnail shows how the page will look. Page size and margin sit under Page settings; Fit to image makes each page exactly the size of the graphic.
Convert and download
Press convert and save the PDF. Your images are left as they were.
Why use this PNG to PDF tool
Genuinely lossless
PNGs are embedded without re-compression, so screenshot text stays sharp and diagram lines stay clean. Nothing is converted to JPEG behind your back.
Transparency is preserved
Images with transparent backgrounds keep their alpha channel rather than being flattened onto black, which is what happens when a tool quietly re-encodes to JPEG.
Built for wide screenshots
A wide screenshot gets a landscape page automatically rather than being shrunk into a portrait one, so it stays readable. Tall and wide images can sit in the same document.
Nothing is uploaded
Everything is read and written by your browser. Screenshots often contain more than you intend — account names, email subject lines, internal dashboards — and none of it leaves your device.
Mixed formats welcome
JPGs can go in the same document, so a set of screenshots and a photo can become one file.
Free, no account
No sign-up, no daily limit, no watermark on the result.

Frequently asked questions
Does converting PNG to PDF lose quality?
No. PNG images are embedded into the PDF exactly as they are, with no re-compression. A screenshot will look identical in the PDF to how it looked on screen.
What happens to transparent areas?
Transparency is kept. The image goes in with its alpha channel intact rather than being flattened, so transparent regions show whatever is behind them — normally the white page.
Can I include JPG files too?
Yes. This tool accepts both PNG and JPG, so a document can mix screenshots and photographs.
Will a wide screenshot fit on the page?
Yes. Each page takes the orientation of the image on it, so a wide screenshot gets a landscape page and is not shrunk unnecessarily. Choosing Fit to image sizes the page to the screenshot exactly, with no borders at all.
How many images can I convert at once?
Up to 20 images, each up to 50 MB, with a combined total of 100 MB. Everything runs in your browser's memory, and these limits keep the tab from running out of it.
Why is my PDF quite large?
PNG is lossless, which makes it big — a full-screen screenshot can be several megabytes on its own, and the PDF stores it unchanged. If size matters more than fidelity, save the images as JPG first.
Are my images uploaded anywhere?
No. Reading the images and writing the PDF both happen in your browser. Nothing is sent over the network, so no copy exists anywhere but your device.
Can I put several images on one page?
Not currently — each image becomes its own page. Setting the margin to none gets each graphic as close to filling its page as possible.
