How do I open an LHA file?

Is converting LHA files free?

Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

Are my LHA files uploaded anywhere?

Files up to 200 MB never leave your device: ConvertKitty runs 7-Zip inside your browser. Only larger files, or formats your browser cannot handle, are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.
