Extract text from Lychee Slicer projects (LYS)
To convert LYS projects to another format, you need Lychee Slicer or other 3D software.
To convert other file formats to the "3D Slicer Project" file type, you need software like Lychee Slicer or a similar tool.
The .LYS file is a 3D printing scene project created by Lychee Slicer. It stores 3D models alongside precise resin printing metadata such as support structures, hollowing, drain holes, and build plate orientation.
Users frequently need to convert these files because .LYS is a proprietary, closed-source format. If you send a .LYS file to someone without a premium subscription or the native software installed, they cannot open it or view the 3D model. The format locks your 3D assets inside a specific software ecosystem, making cross-compatibility with other slicers impossible.
The best conversion targets are universal 3D mesh formats like STL or OBJ. Exporting to these formats typically merges the supports with the model, meaning you lose the ability to dynamically edit the support structures later.
Because .LYS files are complex, proprietary project containers rather than raw 3D meshes, standard online converters usually fail to process them. Often, only the original Lychee Slicer software can properly read or export the embedded 3D data. However, just drag and drop your file into convert.guru to identify the format, inspect the file, and view its internal structure. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your LYS file, detects the exact format, and lets you read the text inside.
Users also converted ZIP, LYT, LY, STL, 7Z, RPP, XAPK, G3D, CDW, WEBARCHIVE, PNG, BAK and SAV files.
If you want to convert LYS file to STL, MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC or APE, you can use Lychee Slicer or similar software from the "3D Printing Slicer Scene" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to LYS, try Lychee Slicer or another comparable tool in the "3D Printing Slicer Scene" 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 LYS converter.
