AI Express supports the upload of three mainstream file formats: PDF, PNG and JPEG, all of which cannot exceed 50MB in file size, which is a uniform limit set by the platform. For files exceeding this limit, users need to compress or split them first. The uploading method is flexible, which can be done by dragging and dropping the file to the designated area of the webpage, or clicking the "Select File" button to select the file from the local area. The system will automatically detect the file format, if the format does not match, it will prompt an error and ask for a new upload.
