How to Convert to PDF

1
Drop your PNG files
Add up to 200 images at once. They are read by your own browser, so nothing is uploaded and nothing waits in a queue.
2
Set page size and background
Choose a page that matches each image or a printable A4 or Letter sheet, set margins, and decide what happens to transparent areas.
3
Download the PDF
One document comes back with a page per image. Turn off merging to get a separate PDF for every file inside a ZIP.

One page per screenshot

Each screenshot becomes a page of one PDF, and the page size starts on “Fit image”: one pixel of the screenshot to one point of the page, with no white edges and no rescaling. A 1280 × 800 laptop capture makes a 1280 × 800-point landscape page, a phone capture a tall, narrow one, and both can share a file. For printing, switch to A4 or Letter: each screenshot is then fitted whole onto the sheet, in portrait or landscape to match it, with margins in millimeters if you want them.

Getting the order right

The PDF follows the numbered list under “Images in order”, top to bottom. It starts in the order the browser received the files, not necessarily the order you took them, so check it: the arrows move a screenshot up or down, the cross removes it, and on a computer the thumbnails can be dragged as well. The finished pages are rebuilt after every change, so a screenshot in the wrong place shows at once. A JPG screenshot is left out with a note; convert it with JPG to PDF, then join both files in Merge PDF, which the “What's next?” row offers.

Transparent edges and very long captures

Most screenshots are fully opaque, but a window captured on a Mac with its shadow has see-through edges. Those areas are filled with white by default; for dark windows, “Transparent areas” under “More settings” fills them with black instead or keeps the transparency. A scrolling capture of a long web page can hit the PDF format's limit: a page side can be at most 14,400 points, or 200 inches. A taller screenshot gets a page scaled down to that length, while the image inside keeps every pixel, so zooming in still shows full detail.

Screenshots on a phone

On a phone, two tabs, Images and PDF pages, replace the side-by-side columns: check the order on the first and the result on the second. The PDF is assembled in the phone's browser, so chat messages and account numbers in the screenshots stay on the device. On an iPhone the download button opens the Share sheet; Android saves to Downloads. In our check on October 20, 2026, three 1280 × 800 PNG screenshots totaling 249 kB became a three-page PDF of 204 kB with the page size following the image. One PDF takes up to 200 screenshots; for more, make two and join them in Merge PDF.

Your images never leave this device

The files are read from your disk, assembled into a PDF and handed straight back as a download. Nothing travels to a server, nothing is stored for us to delete later, and no account is needed. Screenshots of internal dashboards, invoices and private chats are safe to convert here, and the page keeps working with the connection switched off.

Frequently asked questions

What happens to transparent parts of my PNG?

They are filled with a solid background, white by default, before the image enters the PDF. That keeps the page identical in every reader and on paper. Choose the transparent option instead if you want the alpha channel preserved as it is.

Why is the PDF bigger than the sum of my PNG files?

Because PNG pixel data is stored in the document with the compression that PDF understands, which is less efficient than the one PNG uses. Screenshots grow the most. Running the finished file through PDF compression brings the size back down.

Is PNG better than JPG for screenshots in a PDF?

Yes. JPEG compression smears the sharp edges of text and interface elements, and the damage is permanent. PNG is lossless, so menus, charts and code stay crisp at any zoom level. For photographs the tradeoff goes the other way.

How do I change the order of the pages?

Drag the thumbnails in the file list before you start. The document follows that order, top to bottom, no matter how the files are named or in what order your system offered them.

Can I get a separate PDF for every image?

Yes. Turn off the merge switch and each image becomes its own one-page PDF named after the original file. When there is more than one, they come back together in a single ZIP archive.

Do interlaced PNG files work?

Yes. An interlaced file stores its pixels in seven passes so it can appear gradually while loading, which PDF cannot describe. Those files are quietly rewritten in the standard layout first, with no visible change to the image.

Which margin should I use for printing?

Ten millimetres suits most home printers, which cannot print to the very edge of the paper. Combine it with A4 or Letter rather than fit, so every page has the same size and the printer does not rescale anything.

Is there a limit on how many images I can add?

Up to 200 files at a time, two gigabytes each and 500 megabytes in total. For a larger set, convert it in batches and join the resulting documents with the merge tool, which keeps the order you give it.
