Extract text from ADDON files
To convert your ADDON file to another format, you need ReShade or other Plugin software.
To convert other file formats to the "Game Post-Processing" file type, you need software like ReShade or a similar tool.
A .ADDON file is primarily a compiled plugin used by ReShade, the generic post-processing injector for video games. Introduced with ReShade 5.0, these files are technically Dynamic Link Libraries (.DLL) that have been renamed to distinguish them from standard system files. They allow developers to create advanced tools - such as depth-buffer analyzers, texture dumpers, and shader togglers - that hook directly into the ReShade API.
Users frequently encounter friction because .ADDON files are binary executables (PE format), not text files like standard FX shaders. You cannot simply open them in a text editor to modify code, and double-clicking them will trigger a "Windows cannot open this file" error. Because they function as injectors, they may also trigger false positive alerts from antivirus software. While you cannot "convert" a compiled add-on back into editable source code easily, you can rename the extension to DLL to inspect its dependencies or view its internal structure using a resource viewer. For the file to function, it must not be converted but rather placed in the same directory as the game executable or ReShade binary.
Convert.Guru analyzes your ADDON file, detects the exact format, and lets you read the text inside.
Users also converted ADDON64, MCADDON, CPG, RPF, ZIP, RAR, JAR and MOD files.
If you want to convert ADDON file to MOD, DLL, SO, DYLIB, BUNDLE, PLUGIN, XPI, CRX, SAFARIEXTZ, APPEX, KEXT or SYS, you can use ReShade or similar software from the "ReShade Plugin Module" category. In the File menu, look for Save As… or Export….
To convert LV2, DYLIB, VST, AAX, DRV, TDE, LADSPA, BUNDLE, AU, DLL, RTAS or SO files to ADDON, try ReShade or another comparable tool in the "ReShade Plugin Module" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ADDON converter.
