Without downloading new apps, where can I view PDF files?

I need to read a PDF attachment on my work laptop, but I can’t install anything. Where can I open it without downloading another app?

That is annoying when you just need a quick look and cannot install anything. On Windows, save the attachment, then right click the PDF, choose Open with, and pick Microsoft Edge. Dragging the file into an open browser window or pressing Ctrl plus O works too. On a Mac, Preview should open it the same way. Honestly, I would try the browser first because it needs no new software.

Your browser already does this. Drag the PDF into a Chrome or Edge window and it opens right there, nothing to install. On a locked-down work laptop Edge is your best bet since it’s preinstalled, so right-click the file, choose Open with, and pick Edge.

Try dragging the PDF into a Chrome or Edge window, or right-click it and choose “Open with” your browser. I’d avoid uploading a work document to a random online PDF viewer, especially if it contains private information.

Most work laptops can open a PDF directly in Chrome, Edge, or another browser by dragging the file into a browser tab. You can also check whether your email attachment has a Preview option. I would avoid uploading a work document to a random website, especially if it contains customer or company information.
