Are there guidelines for maintaining image quality while optimizing file size?

Yes, there are guidelines for maintaining image quality while optimizing file size. Here are some common techniques:

Choose the right file format: Use appropriate file formats such as JPEG for photographs and PNG for images with transparency. JPEG is a lossy compression format that is great for photographs, while PNG is a lossless format that is better for images with text

Adjust compression settings: When saving images in a program like Photoshop, adjust the compression settings to find the right balance between file size and image quality. Ensure that the image size is less than 2MB.

Resize images: Resize images to the actual dimensions needed on your website.
