Leaf Viewer (leafviewer) Package name

Leaf Viewer is one app for the files on your computer. Open a document, a photo, a song, a film, a ZIP, a 3D model or a map, and it is shown the way it was meant to look. It opens more than 1,700 kinds of file, from this year's and from forty years ago, and it never changes any of them.

Documents look like themselves. A Word file shows as its pages, a spreadsheet as its tables and charts, a presentation as its slides, an e-book as a book, two pages at a time if you like.

Music and films play, with lyrics and subtitles, including the old formats other players gave up on. Photos fit the window, zoom and turn, camera raw and HEIC included.

Look inside archives and disk images without unpacking anything, and open each file where it is.

...and a great many more. If a file you need doesn't open, tell us.

It fits your desktop. It follows your light or dark setting, appears under Open With in your file manager for the files it reads, and never takes a file type from the app you already use. Press F for full screen. Print, or save as a PDF.

It only reads. It never edits, saves or changes the files it opens, and a file from a stranger is shown, never run. Keep editing in your usual app: Leaf updates when you save, and keeps your place. Nothing in a document can reach the internet.

Try it free for 14 days, then US$11.99 for up to 10 computers.
