"What are the ways to reduce high export file size, and is there a recommended minimum size for optimal results?"

A file size of 1 KB to 100 KB is considered small, while anything lower is considered very small, but this doesn't necessarily mean a higher quality file.

A simple text file or a small SVG (Scalable Vector Graphics) file can be as small as 1-10 KB, while high-resolution raster images or high-quality vector graphics may have larger file sizes of up to 1 MB or more.

Unnecessary metadata or unnecessary data can increase file size, making it larger than necessary.

The type of file, complexity of the design, and resolution all impact file size, making it difficult to determine an optimal file size for all files.

Using a preset for the frame size of export and reducing the Level setting from 51 to 4 can significantly reduce file size.

Selecting VBR (variable bitrate) and adjusting the maximum bitrate can also reduce file size while maintaining quality.

Resizing images in Lightroom can be done in various ways, including setting a specific width and height, or using the "Fit" option to resize based on the longest side.

When exporting video, the "Match Sequence Settings" option can affect file size, and unchecking it can reduce file size.

Bit depth customization can also impact file size, with higher bit depths resulting in larger file sizes.

Exporting video with a lower quality setting can reduce file size, but may also affect video quality.

Nested sequences can increase file size, even if the same source files are used.

File size is not always an indicator of image quality, and looking at the number of pixels (height and width) is a better measure of image quality.

Compressing images can reduce file size, but may not always have a significant impact on overall file size, especially in presentations like PowerPoint.

The resolution of images (measured in PPI - pixels per inch) can greatly impact file size, with higher resolutions resulting in larger file sizes.

Reducing image size is not always straightforward, and simply reducing the dimensions of an image may not always result in a smaller file size.
