Convert a file to EFKPKG
To convert other file formats to the "Particle Effect Package File" file type, you need software like Effekseer or a similar tool.
About EFKPKG files
The .efkpkg file is an Effekseer Package format used specifically for bundling real-time particle effects. Game developers and VFX artists use these files to package base effect data (like efkefc or efkproj) together with essential resources, such as PNG or JPG textures, into a single shareable asset. You can open and edit these files using Effekseer, a free, open-source particle effect creation tool popular for integrating 3D visual effects into game engines like Unity, Unreal Engine, and WebGL.
Users often need to convert these files to share the visual output with non-developers, clients, or on social media. However, the .efkpkg format is a proprietary container, meaning it has significant real-world limitations. It requires the user to install specialized software just to see what the effect looks like and is not supported by standard media players, web browsers, or image viewers. Because the file stores mathematical logic, spawn rates, and 3D coordinates rather than pre-rendered pixels, standard online video converters fail entirely when trying to process it.
If your goal is to showcase the animation, your best option is to render the effect natively inside Effekseer to a standard MP4 video, a GIF, or a PNG sprite sheet. Doing so will bake the visual data but remove any interactive or real-time 3D properties.
This format is notoriously difficult to process because the proprietary nodes and parent-child particle relationships must be calculated in real-time by the game engine. Often, only the original software can properly read or export the visual data. If our analysis detects standard supported embedded formats - such as the underlying texture images - viewing or extraction may still be possible without launching a game engine.
Convert.Guru analyzes your EFKPKG file, detects the exact format, and lets you read the text inside.

The EFKPKG Converter Story
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 EFKPKG converter.
