bitsmol is a desktop video compressor for Windows. The free version is provided at no cost. bitsmol Pro is a one-time purchase that unlocks additional features (batch compression and send-from-phone).
A bitsmol Pro purchase grants you a personal licence to use the Pro features on your own machines. Please don't share, resell, or redistribute your licence key. Licence keys are validated through Gumroad.
Use bitsmol only with videos you have the right to process. You are responsible for the content you compress.
bitsmol is provided "as is", without warranty of any kind. While it's built with care, the developer isn't liable for any data loss or damages arising from its use. Always keep your original files until you've checked the result.
Refunds for Pro purchases are handled according to Gumroad's refund policy. If something's wrong, email us and we'll try to help.
