ExeBrowser

Load your own EXE and run it here

Runs via Wine 1.7.55 (Win32) + Boxedwine on WebAssembly · Nothing is uploaded · No account

Drop a Windows executable below — or the whole folder, or a zip of it — and it runs inside this browser tab. The file is read on your own machine and copied into a virtual C:\ drive that exists only in the tab's memory. There is no server involved in running it, no installer, and nothing left behind when you close the page.

First run downloads the Wine runtime (~30–60 MB) and caches it. Click the screen to capture mouse and keyboard; press Esc to release.

Which of the three options to use

They all end in the same place — files staged into the virtual drive — but they suit different things on your disk.

• A single EXE — for a self-contained program: an old utility, a single-file game, a portable tool. If it runs on a real PC by double-clicking it and nothing else, this is the one.
• A folder — for anything with .dll, .dat, .ini or asset files beside it. This is most real software, and it is the option people skip before concluding their program does not work. The folder is staged whole and you pick which .exe starts.
• A zip — the same as a folder, for when you have the archive rather than the unpacked directory. Handy on mobile browsers, which do not offer folder selection.

If the program needs a data file to work on — an archive to extract, a document to open — put that file in the folder too before loading it. Nothing inside the tab can see your real disk, so anything the program should open has to come in with it.

What runs, and what honestly does not

This is an emulated 32-bit Windows environment, not a compatibility layer over your real machine, and it is worth knowing where the line falls before you spend a download on it.

Works well

• 32-bit Win32 and GDI applications from roughly 1995–2008 — editors, viewers, calculators, archivers, small utilities.
• 2D games of that era, including plenty that will not start on Windows 11 any more.
• Old installers, when what you want is the files inside rather than an installed system.
• 16-bit Windows 3.x software, using the Wine 3.1 · 16-bit engine in the picker above.

Usually does not

• 64-bit programs. The default engine is 32-bit only. There is an experimental 64-bit runtime with its own loader, but many things do not render in it yet.
• Direct3D and modern 3D games. There is no GPU passthrough here.
• .NET, modern Visual C++ runtimes, and anything expecting Windows 10 APIs. Wine 1.7.55 predates them.
• Anything needing the network, a licence server, or real hardware — dongles, printers, serial devices, disc checks.

Speed sits around 10–40% of native, because every x86 instruction is emulated. Fine for a utility or an old game; not fine for anything heavy. The compatibility guide goes through the categories in more detail, and we tested 53 real applications and published what happened to each one.

If it does not start

1. Load the folder, not the lone EXE. A missing DLL beside the program is the single most common failure, and it usually looks like nothing happening at all.
2. Check it is 32-bit. Many downloads default to the 64-bit build now; the 32-bit release of the same version often runs fine here.
3. Try another engine. Boxedwine 18R2 sometimes runs what the default chokes on, and an app that asks for Internet Explorer needs the + Gecko option.
4. Read the console. The Console output section under the screen shows what Wine actually complained about — usually a named missing DLL or an unimplemented call.
5. It might be an installer, not the program. Run it anyway, let it unpack, then use Download files written by this app to pull out what it wrote. Extracting an old installer covers the alternatives.

Where your file goes

Nowhere. The .exe is read locally with the browser's file API and written into an in-memory filesystem that Wine sees as C:\. No part of it is transmitted, and there is no server-side copy to delete because one is never made. When you close the tab the virtual drive is gone; files a program saves are kept in this browser only so you can pick up where you left off, and Download files written by this app gets you a copy you keep.

The page itself uses Google Analytics for page metrics and Google AdSense for ads. Neither can see your file, the virtual drive, or anything the program does — they are ordinary page-level scripts and the emulator's memory is not something they have access to. Details in the privacy policy.

Nothing to load? There is plenty here already

Most people arrive without an .exe to hand. We host a shelf of free, licence-clean games and applications that boot in one click — DOOM, Space Cadet Pinball, Solitaire, SkiFree, 7-Zip and several dozen more — no upload needed.
