Extract text from SLP files
To convert your SLP file to another format, you need Project Slippi or other Game software.
To convert other file formats to the "Replay Data File" file type, you need software like Project Slippi or a similar tool.
The .SLP extension is a classic example of file format collision, serving three distinct communities with completely incompatible data structures.
Most frequently, you have a Project Slippi Replay file. These are not video files; they contain input data (controller inputs, game state, RNG seeds) used to reconstruct a match of Super Smash Bros. Melee inside the Dolphin Emulator.
The Problem: Because they are just metadata, you cannot double-click an .SLP file to watch it in VLC, Windows Media Player, or upload it to YouTube. The file size is tiny compared to video, but useless without the game engine.
The Solution: To share these replays, you must render them into a standard video format. You typically use the Slippi desktop app to playback the file and capture the window to MP4, MOV, or AVI using screen recording software like OBS Studio.
Alternatively, if you are a modder for Age of Empires (the classic RTS game), your .SLP file is a proprietary raster graphic container storing unit animations and terrain sprites. These files are locked inside an outdated format not recognized by modern editors like Adobe Photoshop. To edit these assets, you need specialized community tools (like SLP Studio) to extract the frames into BMP or PNG sequences.
Finally, in enterprise environments, an .SLP file might be a SnapLogic pipeline. These are actually just standard JSON files describing data integration flows. If you cannot open one, try renaming the extension to JSON to view the raw text in VS Code or Notepad++.
Convert.Guru analyzes your SLP file, detects the exact format, and lets you read the text inside.
Users also converted MP3, M4A, ZIP, AUP3, REPLAY, SPL, PLAN, FLP, RVZ, MPA, PHP, AXS and MP4 files.
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 SLP converter.
