OpenAnyFile
Works
Viewing, inspecting and verifying. You get each page rendered to an image by a real PostScript interpreter compiled to WebAssembly. File details, exact byte size and the detected signature are always shown.
How to open a .ps file
If double-clicking a PS file did nothing useful, that is normal: the format is fine, your operating system just has no default application registered for it. This page explains the format and gives you a way to read one immediately.
What is a .ps file?
PostScript is a vector graphic format developed by Adobe, first appearing in 1984. It is normally produced by LaTeX/dvips, printer drivers.
Actually a Turing-complete programming language that describes a page. Rendering it means executing it, which is why a PostScript file can loop forever on a printer.

Open a .ps file in your browser
OpenAnyFile routes .ps to its Ghostscript WASM engine, which rasterises each page rendered to an image by a real PostScript interpreter compiled to WebAssembly.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .ps 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 Ghostscript WASM engine.
- Your PS opens on its own viewer page: each page rendered to an image by a real PostScript interpreter compiled to WebAssembly.
- 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.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
No upload, and here is why that matters for {E}
Handing a .ps file to a random conversion site means handing over a copy you cannot get back. OpenAnyFile parses the file locally instead — the same way special software reads it off your disk, except the reader happens to be a web page. Nothing is transmitted, so there is nothing to leak, log or subpoena. It also means it keeps working with your Wi-Fi switched off.
Frequently asked questions about PS files
Can I open a .ps file without installing special software?
Yes. OpenAnyFile's Ghostscript WASM engine runs in your browser, so you can read a PS file with nothing installed. You get each page rendered to an image by a real PostScript interpreter compiled to WebAssembly. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a PS file?
Look at the first bytes rather than the extension. A genuine PS begins with 25 21 50 53 (%!PS). Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .ps by mistake is easy to spot.
Is it safe to open a PS 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 .ps file, exactly?
PostScript — an application/postscript format created by Adobe since 1984. Actually a Turing-complete programming language that describes a page. Rendering it means executing it, which is why a PostScript file can loop forever on a printer.
Does the same viewer handle formats related to PS?
Yes — the same engine also opens .ai, .eps, .svg, 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 .ps file, it will open too:
