Notepad and Classic Win32 Utilities in a Browser — Load Your Own

Running Notepad and classic Win32 utilities in your browser Works well — the most reliable category

Guide updated July 2026 · Runs via Wine 1.7.55 (Win32) + WebAssembly · Requires your own copy

If you want to see ExeBrowser work with the least possible friction, a tiny classic Win32 utility is the place to start — load your own copy below and it runs entirely in your browser tab. A plain text editor, a hex editor, a small calculator, an old file manager — these are single-purpose, decades-old programs that barely touch the parts of Windows that Wine struggles with. They boot fast, behave, and almost never break. Notepad itself is Microsoft software (so bring your own copy), but the wider world of small free utilities runs beautifully here — load any one of them and watch a real .exe open in a browser tab.

Runs in your browser tab with WebAssembly + Wine — nothing is uploaded. Click the screen to capture input; press Esc to release the mouse.

About Notepad itself: NOTEPAD.EXE, Calculator, and similar built-in Windows accessories are Microsoft software and are not redistributable, so we don't host them here — bring your own copy from a Windows machine you own. The good news: this category isn't really about Microsoft's tools. The most reliable, instant things to run are the countless free and open-source tiny Win32 utilities — text editors, hex editors, viewers and converters — many of which are explicitly free to redistribute. Use Load your own copy above to drop in any small .exe you legally have.

How it works & what to expect

Why small utilities are the most reliable category

The things that break apps under browser-based Wine are modern GPU features, 64-bit code, recent .NET, DRM, and Win32 APIs added after Windows 7. Small classic utilities use none of that. They draw a plain window with standard controls, read and write files, and quit. That maps almost perfectly onto what Wine 1.7.55 implements well, so the failure rate is very low.

If you've never tried ExeBrowser, run one of these first to get a feel for booting Wine, capturing input on the canvas, and pulling your output back out. The 1995–2008 32-bit Win32 era is the engine's sweet spot, and tiny tools sit right in the middle of it.

Editing and saving a file — the round trip

A text editor is the perfect demo of getting work in and out. Boot Wine, run the editor, type or open something, then use Download files written by this app to pull the saved file back out of the in-memory C:\ as a zip.

One thing to remember: the virtual drive is wiped on reload, so download before you close the tab. To continue later, re-upload that zip alongside the EXE. A single .exe is usually all you need to load; if a tool asks for DLLs, bundle the whole folder instead.

Other utilities worth trying

Hex editors — inspect or patch a binary on a Chromebook with no native tooling.
Old shareware calculators and unit converters — single-EXE, instant, no setup.
Classic file managers — browse the virtual drive, handy alongside an archiver like 7-Zip.
VB6 and Delphi mini-apps — these run well; bundle the runtime DLLs in the folder if the app prompts for them.
Plain-text editors and Notepad clones — Notepad2, metapad and similar lightweight free editors load instantly.

What about Notepad itself, and Calculator?

Microsoft's built-in accessories — NOTEPAD.EXE, CALC.EXE, Character Map, WordPad — are proprietary and not redistributable, so we can't ship them for you. If you have a legally-owned Windows install, you can copy the EXE off it and load it here; the classic non-UWP versions are small Win32 programs and run fine. Otherwise, reach for a free open-source equivalent: it'll do the same job, run just as cleanly, and you can keep it.

Frequently asked questions

Can I run Notepad in my browser for free?

You can run a Notepad-style editor with no install, but Notepad itself (NOTEPAD.EXE) is Microsoft software we can't host. Either copy the EXE from a Windows PC you own and load it with Load your own copy, or use one of the many free open-source text editors that run just as cleanly here.

Why are small utilities the most reliable things to run?

Tiny classic tools only use standard windows, basic controls, and file I/O — none of the modern GPU, 64-bit, recent .NET or DRM features that trip up browser Wine. That maps almost perfectly onto what Wine 1.7.55 supports, so they boot fast and rarely fail.

How do I get a file I edited back out of the browser?

Save inside the app, then use Download files written by this app to pull the result out of the in-memory C:\ as a zip. The virtual drive is wiped on reload, so download before you close the tab — and re-upload that zip next time to continue.

My utility says it's missing a DLL — what do I do?

A single EXE is usually enough, but VB6, Delphi and some other apps need runtime DLLs. Put the EXE and its DLLs in one folder on your computer, then load the whole folder instead of just the EXE so Wine can find them.

Which Wine variant should I pick for utilities?

Use the default (Win32) variant — it's the everyday choice and handles 1995–2008 utilities best. If a particular tool crashes on boot, the r18 (older engine) variant is worth a try as a fallback.
