About EXE
An EXE is a Portable Executable, the format of Windows programs since Windows NT 3.1: a header, then sections of code, data and resources, which hold its icon, its version details and a manifest saying whether it needs an administrator's rights. Setups are EXEs too, with the program they install packed inside.
Programs are signed with Authenticode: a signature over the file's hash, made with a certificate a CA issued to the publisher, and a timestamp that keeps it good after the certificate expires. Windows names the publisher from it when it asks to run the program, and SmartScreen weighs it.
Filepeek checks the signature, the certificate chain and the timestamp inside your browser, and Check now asks the CA whether it revoked the certificate, only when you press it. It reads the version details and the manifest, names the setup that made an installer, reads an NSIS setup's script for what it does, and names a .NET program's runtime and the assemblies it references.

Questions
How do I see what an EXE is without running it?
Drop it on this page or choose Peek an EXE. A page shows its name, version and publisher, what it runs on and whether it asks for an administrator's rights, and a setup's files are listed like a folder. Nothing runs.
How do I check an EXE's digital signature?
Filepeek checks its Authenticode signature, the certificate chain up to the CAs Windows trusts and its timestamp, and says who signed it and when. Check now asks the CA whether it revoked the certificate.
How do I look up an EXE on VirusTotal?
Filepeek works out its SHA-256 inside your browser. Look up on VirusTotal opens VirusTotal's page for that hash, and only the hash goes, never the file. Compare checks it against a SHA-256, SHA-1 or MD5 you paste.
Does opening an EXE run it?
No. Filepeek only reads it: nothing in it runs and it never leaves your device.
Can I get files out of an EXE?
Yes. Pick any file on the left to open it. A setup's files and an NSIS script open at once. Export saves them all as a ZIP, or, in Chrome and Edge on a computer, extracts them into a folder.
