+# image converter
+
+## установка
+создание виртуального окружения:
+- python -m venv venv
+
+активация виртуального окружения:
+windows:
+- Powershell:  `.\venv\Scripts\Activate`
+- CMD: `venv\Scripts\activate.bat`
+
+linux&mac:
+- ` source venv/bin/activate`
+
+Установка зависимостей:
+- `pip install -r requirements.txt`
+
+запуск:
+-` python main.py`
+
+## использование
+`input original format` оригинальный формат конвертируемых файлов
+
+`input target format` формат, в который будет конверт
+
+`select mode (single or mass)`
+- single - указываете точный путь до файла
+- mass - указываете путь до каталога с изображениями
