Before sending a large file, check whether it contains unnecessary images, pages, attachments, or other data. Removing unused content is often an easy first step. You can also compress the file using a suitable tool or reduce the quality of large images and videos. Try to balance file size with readability and visual quality, especially for professional documents. Keeping the original file as a backup is also recommended. Understanding how to minimize file size makes it easier to share files through email, messaging apps, and online platforms.
