Select a file. Press Space. See more.
Peek Preview is an independent extension for file previews in Finder. Select a file and press the Space bar. Play a video, look inside an archive, read colorful code or rotate a 3D model. Right where your files already live.
80+ FILE EXTENSIONS. FIVE PREVIEW EXTENSIONS.
Peek adds missing previews and makes other content easier to read. Its coverage includes additional and enhanced previews for media, archives and books, code and data, 3D models, and NFO. Not every extension is a format that macOS could never display before.
MKV. PRESS SPACE.
Play supported MKV, WebM, AVI and other media files in the preview. Jump to your scene or listen to FLAC, Ogg and Opus. Bundled FFmpeg playback handles supported codecs locally on your Mac.
GET INSIDE THE ARCHIVE.
See what’s in your download. Expand folders, check file sizes and inspect RAR, 7z, ZIP and TAR entries, including supported GZ and XZ variants. No unpacking needed.
SELECT YOUR FILE. SPIN YOUR MODEL.
Explore GLB, self-contained glTF, supported 3MF, OBJ and PLY models interactively. Rotate the object in fixed light, zoom into the details and restore the initial framing with Reset View. STL stays with macOS.
CODE. IN FULL COLOR.
Give common source and configuration files syntax colors, adjustable font size, optional line numbers and wrapping. Your display, your choice. The original file stays untouched.
MARKDOWN. MADE FOR READING.
Turn your README into a formatted document, with headings, lists, tables and highlighted code blocks. Switch to the source whenever you need it. Select a small fragment or copy the entire file text with one click, without displayed line numbers.
EXPAND YOUR JSON. DISCOVER THE DETAILS.
Explore JSON, XML and property-list trees. See CSV and TSV as tables. Inspect SQLite schemas and sample table rows read-only. Subtitles, Jupyter notebooks, HAR, SARIF, Xcode String Catalogs and NZB get dedicated views too.
ONE BOOK. ONE SPACE BAR.
Read chapter content from supported, unencrypted EPUB books. See the title and author before launching your reading app.
NFO WITH CHARACTER.
Keep classic NFO files and ANSI art readable, with configurable fonts, text size, encoding and colors.
MORE PREVIEWS. YOUR FILES UNTOUCHED.
Peek extends the preview. It does not change default apps or edit your files. Enable the formats you need in settings. Previews also adapt to Finder’s Get Info window.
ALL ON YOUR MAC.
No accounts. No ads. No tracking. No subscriptions or in-app purchases. Processing is local, using read-only access to selected files.
Requires macOS 14 or later. Coverage includes extension variants and source/configuration files. macOS chooses the available preview extension; another provider may take precedence. Unsupported codecs, encrypted files and external resources may limit previews.
