File Converter is a GPT that offers a wide range of file conversion services. It is designed to handle various types of file formats and can convert them to your desired format. This GPT is integrated with ChatGPT Plus, and it generally functions through dialogues or command-like interactions where users specify the current file type and the format they want to convert it into. The requests can range from image conversions such as 'PNG to JPEG', or 'JPG to 16:9 aspect ratio', to text document conversions like 'txt to markdown'. Additionally, File Converter can also compress images to a user-specified size, such as reducing an image to 3 MB. The service, provided by Nextgrid Sp. z o.o., streamlines the file conversion process, making it an efficient tool for users who regularly deal with various file types and formats. Users need to sign up to interact and utilize this tool, and the welcoming interface aims to engage the user with a friendly hello, before aiding them with their file conversion needs.
