Practical explanation
JPG to 100KB files can be too large for upload, email, or web publishing.
Use resizing first, then lower JPG quality until the file approaches 100KB.
Use compression for smaller byte size, resizing for fewer pixels, and conversion when the current format is not right for the destination. Very small targets can require visible tradeoffs, so compare the preview before downloading.
