OpenAnyFile
Works
Viewing, inspecting and verifying. You get the source with language-aware colouring and line numbers. File details, exact byte size and the detected signature are always shown.
How to open a .ps1 file
You have a PS1 file and nothing on your machine will touch it. Here is what the format actually is, and how to read one in about four seconds without installing anything.
What is a .ps1 file?
PowerShell Script is a code format developed by Microsoft, first appearing in 2006. It is normally produced by Windows administration, DevOps.
Passes .NET objects between commands rather than text. Blocked by default execution policy, which is why scripts often need Unblock-File.

Open a .ps1 file in your browser
OpenAnyFile routes .ps1 to its syntax highlighter, which highlights the source with language-aware colouring and line numbers.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .ps1 file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the syntax highlighter.
- Your PS1 opens on its own viewer page: the source with language-aware colouring and line numbers.
- Use fullscreen for a closer look, or download the file back out unchanged. Works the same on Windows, macOS, Linux, Android and iOS, because it is just a web page.

Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
Is it safe to open a {E} file on a website?
It depends entirely on whether the website uploads it, and almost all of them do. That is a real problem when the code file in question is a contract, a client deliverable or something under NDA. OpenAnyFile removes the question: the decoding happens inside your browser tab, so there is no transfer, no queue, no temporary storage and no retention window to read about in a privacy policy.
Frequently asked questions about PS1 files
Can I open a .ps1 file without installing special software?
Yes. OpenAnyFile's syntax highlighter runs in your browser, so you can read a PS1 file with nothing installed. You get the source with language-aware colouring and line numbers. For full editing you still need the original application — this is a viewer, not an editor.
How can I tell what a .ps1 file actually contains?
The .ps1 extension carries no fixed signature, so the extension alone proves nothing. Opening it in OpenAnyFile shows the raw header bytes and detected type, which is the only reliable way to identify one.
Is it safe to open a PS1 file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .ps1 file, exactly?
PowerShell Script — an application/x-powershell format created by Microsoft since 2006. Passes .NET objects between commands rather than text. Blocked by default execution policy, which is why scripts often need Unblock-File.
Does the same viewer handle formats related to PS1?
Yes — the same engine also opens .html, .xml, .sql, so you can compare related files without switching tools.

These open with the same engine, so if you have one of these sitting next to your .ps1 file, it will open too:
