OpenAnyFile
Works
Viewing, inspecting and verifying. You get a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis. File details, exact byte size and the detected signature are always shown.
How to open a .sav file
SAV files come from SPSS, survey and social research, and the usual advice — buy the software that made it — is rarely what you need just to look inside one. This page covers what the format is and how to open it in a browser tab.
What is a .sav file?
SPSS Data File is a binary & system format developed by SPSS Inc., now IBM, first appearing in 1968. It is normally produced by SPSS, survey and social research.
Stores the data together with variable and value labels, so the original questionnaire wording travels with the numbers instead of living in a separate codebook.

Open a .sav file in your browser
OpenAnyFile routes .sav to its universal hex inspector, which inspects a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .sav 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 universal hex inspector.
- Your SAV opens on its own viewer page: a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis.
- Use fullscreen for a closer look, or download the file back out unchanged. No account, no upload, no watermark, no file-size gate.
What you can and cannot do with it here
Does not work
Full-fidelity rendering. This extension has no standard structure, so you get a byte-level inspection rather than a rendered view.
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 binary & system 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 SAV files
Can I open a .sav file without installing special software?
Yes. OpenAnyFile's universal hex inspector runs in your browser, so you can read a SAV file with nothing installed. You get a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis. It will not replace the original application for editing, but it answers 'what is in this file' in seconds.
How can I check a file really is a SAV file?
Look at the first bytes rather than the extension. A genuine SAV begins with 24 46 4C 32 ($FL2). Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .sav by mistake is easy to spot.
Is it safe to open a SAV 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 .sav file, exactly?
SPSS Data File — an application/x-spss-sav format created by SPSS Inc., now IBM since 1968. Stores the data together with variable and value labels, so the original questionnaire wording travels with the numbers instead of living in a separate codebook.
Does the same viewer handle formats related to SAV?
Yes — the same engine also opens .dll, .doc, .exe, so you can compare related files without switching tools.
