Resource Tuner

Resource Tuner is a Windows resource editor for viewing, modifying, and extracting resources from executable files without access to source code.

What is Resource Tuner?

Resource Tuner is a desktop application for Windows (11/10/8/7/XP, 32-bit and 64-bit) that lets you open executable files—EXE, DLL, MUN, SYS, ACM, OCX, SCR, MSSTYLES, and binary .RES—and inspect, extract, replace, edit, or delete their embedded resources such as icons, strings, images, dialogs, menus, version information, and more. Developed by Heaventools, it works on compiled PE files and does not require recompilation.

Key Features

• UPX Unpacker — Automatically detects and decompresses UPX-packed executables so you can edit their resources.
• Wizard-Style Editing — A user-friendly interface for adding and modifying resources like manifests and themes, requiring no programming knowledge.
• Resource Filter and Search — Quickly locate specific resources across multiple files using customizable filters and a powerful search tool.
• Multilingual Interface — Available in 14 languages including English, Spanish, German, French, Chinese, Japanese, and Russian.
• Delphi Form Editing — View and edit properties of controls on Delphi forms and packages within PE files (see Delphi forms).

FAQ

Can I edit executable files without source code?

Yes. Resource Tuner modifies the compiled resources directly—no source code or recompilation needed.

What file types are supported?

EXE, DLL, MUN, SYS, ACM, OCX, SCR, MSSTYLES, and binary .RES files, both 32-bit and 64-bit.

Why can't I see dialogs or menus in some executables?

Programs compiled with Visual Basic or .NET store their UI in non-standard formats, so only icons and version info are available for editing.

Is there a command-line version?

Yes, Resource Tuner Console is a separate script-driven tool for automating resource edits.

What is the difference between the trial and full version?

The trial is fully functional for 30 days with no feature restrictions. After the trial, you must purchase a license to continue using the software.
