Since 2000, Heaventools Software has been developing and marketing software developers' tools, with specialization in the portable executable (PE) file format. In addition to PE Explorer, we also offer Resource Tuner, a PE Explorer spin-off application that makes it simple to view, edit, and replace icons, strings, bitmaps, version information, and any other resources in 32-bit Windows programs; Resource Tuner Console, a program to instantly change icons and strings in compiled 32- and 64-bit EXE or DLL files from the command line; and FlexHex Hex Editor, an application for browsing and hex editing binary data in any files, logical devices, and physical drives.
