One reader for every kind of document

Every kind of document, in one window

Super Preview picks the right view for each file. Open several at once and switch between them in the sidebar.

PDFs

Turn the pages and follow the links inside. Zoom in and out to read the small print.

Word and OpenDocument files

Read .docx and .odt files as clean pages. You don’t need an office suite.

Spreadsheets

Open .xlsx, .xls, .ods, .csv and .tsv files. A workbook with more than one sheet gets a tab for each.

eBooks and comics

Read .epub books with their table of contents. Comics in .cbz can show two pages side by side.

Pictures

Fit a picture to the window, or see it at its actual size. PNG, JPEG, GIF, WebP and SVG all open.

Markdown, code and text

Markdown shows as a clean page, with a switch to see the source. Code gets colours and line numbers, and a JSON file can open as a tree.

Always the latest version

Change a file in another app, then come back. Super Preview shows the new version.

A look that fits your desktop

Pick the macOS, Windows or GNOME style, in light, dim or dark. Then choose an accent colour.
