Extract text from KiriKiri packages (XP4)
To convert XP4 packages to another format, you need KiriKiri or other Game software.
To convert other file formats to the "Game Package Archive" file type, you need software like KiriKiri or a similar tool.
.XP4 files are highly specialized archive containers used by the KiriKiri visual novel scripting engine. Functioning similarly to standard ZIP files but built for proprietary game software, these packages store all essential game assets - such as character sprites, background images, voice audio, and text scripts - in a single compressed file. They are predominantly found in Japanese visual novels and doujin games.
A significant limitation of the .XP4 format is its proprietary and closed nature. Standard archive extraction tools like WinRAR or 7-Zip cannot read these files because developers frequently implement custom encryption layers, obfuscation, or proprietary headers to protect their game assets from piracy or unauthorized modification. Users typically need to extract these archives to access the raw data for translation, modding, or archival purposes, requiring specialized community-built extraction software like GARbro or krkrExtract.
The ultimate goal of converting or unpacking an .XP4 file is usually to extract standard formats like ZIP for the full archive, or individual raw assets such as PNG or JPG for images, and OGG or WAV for audio. However, you should be aware that internal image formats might be stored as proprietary TLG files, and scripts may remain in compiled formats that require further decoding.
Because of the custom encryption used on a game-by-game basis, standard online converters universally fail to process these packages. We can identify the file format, inspect the underlying container structure, and attempt to reveal internal headers, text, or embedded assets. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your XP4 file, detects the exact format, and lets you read the text inside.
If you want to convert XP4 file to EXE, ISO, BIN, CUE, PAK, WAD, PK3, PK4, BSP, MAP, SAV or DAT, you can use KiriKiri or similar software from the "Visual Novel Asset Archive" category. In the File menu, look for Save As… or Export….
To convert MOD, BIN, CFG, SCX, DAT, MPQ, LOG, CUE, INI, EXE, SCM or ISO files to XP4, try KiriKiri or another comparable tool in the "Visual Novel Asset Archive" 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 XP4 converter.
