Convert between ASCII and binary STL — auto-detects the current format
Works with any file size -- files over 50MB may just take a little longer
What is this tool?
Converts an STL file between its ASCII (human-readable text) and binary (compact) representations, auto-detecting which format your file is currently in.
How to use it
Upload your STL file, and convert it to either ASCII or binary format. Download the converted file.
Binary STL files are significantly smaller than the equivalent ASCII version for the same geometry — if file size matters for storage or transfer, binary is almost always the better choice.
