How to combine screenshots into one PDF

Drop them below and download the PDF. Nothing is uploaded — the file is built here, in your browser. The platform-specific routes are further down.

Why the page order is the hard part

Merging images into a PDF is not difficult. Getting them out in the order you took them is, and every built-in route hands that decision to something other than you.

The usual culprit is filename sorting. A folder of captures called Screenshot 9.png and Screenshot 10.png sorts the tenth before the ninth in any tool that compares filenames as plain text, because 1 comes before 9 one character at a time. macOS and Windows both sort numerically in the file manager, so the folder looks right — and then a tool that doesn't reorders them silently on the way into the PDF.

Two habits make this stop happening. Rename with zero padding — 01, 02, 09, 10 — which is correct under both sorting rules. Or use something that shows you the sequence and lets you drag it into place before exporting, which is what the numbered thumbnails above are for.

On a Mac — Finder's Create PDF

Built in since Mojave, and the fastest route if the files are already saved:

1. Select the screenshots in Finder. Click the first, then Shift-click the last.
2. Right-click the selection and choose Quick Actions → Create PDF.
3. A PDF appears in the same folder, named after the first file.

The page order follows the order the Finder window is currently sorted in, so switch the window to sort by name or date before selecting. If you need a different order entirely, open the images in Preview instead, drag the thumbnails in the sidebar into place, then use File → Print → PDF → Save as PDF.

On Windows — Microsoft Print to PDF

No install needed; the PDF printer has shipped with Windows since 10.

1. Select the screenshots in File Explorer.
2. Right-click and choose Print.
3. Set the printer to Microsoft Print to PDF, and the layout on the right to Full page photo.
4. Click Print and choose where to save the file.

Two things to watch. The layout defaults to a contact-sheet grid on some machines, which puts four screenshots on a page at a size nobody can read — set it to full page. And Fit picture to frame, on by default, crops the edges of anything whose shape doesn't match the paper; for screenshots you almost always want it off.

On iPhone or iPad

iOS will build the PDF from the share sheet:

1. In Photos, tap Select and pick the screenshots.
2. Tap the share button, then Print.
3. On the print preview, pinch outwards on the thumbnail. The preview becomes a PDF.
4. Share that from the button at the top to save it to Files.

The pinch is undiscoverable and has been in iOS for years. If you would rather not rely on it, select the images in the Files app instead, long-press the selection, and choose Create PDF — same result, in the folder you are looking at.

Which route should you use?

• Files already saved, order doesn't matter: the OS route. Nothing to open, nothing to install.
• The order matters, or you want to check it first: the tool at the top of this page. The numbers on the thumbnails are the page numbers.
• The screenshots don't exist yet: capture them somewhere that keeps them grouped, so there is no folder to tidy afterwards. That is the job Stik does.

Skipping the folder entirely

Every route on this page starts from the same place: a pile of files on disk that you captured one at a time, then have to find, sort and clean up. For a one-off that is fine. Doing it weekly, the filing is most of the work.

Stik sits in Chrome's side panel and collects shots as you take them, bundled into named groups in the order you captured them. The group is the unit you work with afterwards — paste the whole set into Slack or Notion with one ⌘+V, or export it and drop it straight into the tool above with the order already correct. Nothing is uploaded there either; captures live in your browser's local storage.

Questions

Are my screenshots uploaded anywhere?

No. The PDF is assembled by JavaScript running in this tab — your images are read from disk, drawn to a canvas, and written into a file your browser then saves. Nothing is sent to a server, and the tool keeps working with your network disconnected.

How many screenshots can I combine at once?

There is no fixed limit — the ceiling is your device's memory. Thirty full-page captures is comfortable on a normal laptop. Images larger than about 30 megapixels are scaled down first, because browsers stop painting a canvas past that size and would otherwise produce blank pages.

What page size should I choose?

Fit to image gives each page the exact proportions of the screenshot on it, so there is no white border to crop — the right pick for sharing and reading on screen. Choose A4 or Letter when the PDF is going to be printed or dropped into a document template.

Why is my PDF so large?

Lossless keeps every pixel exactly as captured, which matters for small text but grows with the number of shots. Switch the quality control to Smaller file to store the pages as JPEG instead — typically a fifth of the size, at the cost of faint artefacts around sharp edges.

Does it work on iPhone and Android?

Yes. The page works in mobile browsers, and the file picker offers your photo library. On a phone the built-in share sheet is usually quicker, so the platform steps above are worth reading first.
