Open any file.
Open any file.
Any format. Instantly.
Drop in a file with any extension — video, Photoshop, Word, spreadsheets, code, archives, fonts, or something nobody has heard of. It opens right here, and it is never uploaded.

A dedicated viewer for every kind of file
Each family of files gets its own purpose-built viewer, so a spreadsheet never looks like a video.
Camera RAW
The full-size preview from Canon, Nikon, Sony, Fuji and 20 more RAW formats.
Video
Play MP4, MKV, WebM, MOV and more — and even run old Flash SWF files.
Audio
Stream music and recordings instantly, lossless formats and tracker music included.
Documents
PDF page by page, Word and RTF as clean text, even old binary .doc files.
Spreadsheets
Every sheet as a scrollable table — XLSX, XLS, ODS, CSV, Numbers.
Design files
Photoshop, Krita, Procreate, Sketch and more, shown from their embedded previews.
Archives
Click into ZIP, RAR, 7Z and TAR folders and open any file inside.

Certificates & keys
Read certificates and extract the document inside signed .p7m files.
Executables
Inspect EXE, DLL, ELF and WebAssembly safely — without running them.
System & binary
Anything else gets a hex view, its real signature, checksums and readable text.
More than a viewer
Identifies the real format
Files are detected by their magic bytes, so a renamed or extension-less file still opens correctly.
Checksums built in
SHA-256, SHA-1 and MD5 for any file, computed on your device — verify a download in seconds.
Several files at once
Drop a whole batch; each file gets its own tab. Archives inside archives open too.
Opens from your desktop
Install it as an app and use "Open with" or the share sheet to send files straight to it.
Works offline
After the first visit the opener keeps working without an internet connection.
Private by design
There is no upload server at all. Your files stay on your device, always.
How it works

Drag a file in, choose it, or paste it.
