FTP to Dropbox on Mac?

I’m looking for a working solution to transfer files from FTP server to Dropbox on Mac. I often receive large files from clients via FTP, and manually downloading and re-uploading them to Dropbox is both time-consuming and inefficient. Ideally, I’d like a solution that can securely connect to an FTP server and sync or transfer files directly to a designated Dropbox folder. Are there any tools or services you’d recommend that work well for this purpose? Thanks in advance for your help.
