Difference between uploading through a browser and a program?

Uploading through a browser typically involves using a graphical interface that allows users to drag and drop files or select them from their device, making it user-friendly and accessible. In contrast, uploading through a program often requires command-line interactions or API integrations, which can offer greater control, automation, and speed for bulk uploads. While browsers may impose file size limits and require active sessions, programs can handle larger files and automate repetitive tasks more efficiently.
