For web use, consider resizing to maximum 1920px width for full-screen displays. Use quality settings of 80-90% for a good balance between file size and visual quality.

JPG format is best for photos with many colors, while PNG is ideal for graphics with transparency. WebP format offers superior compression with excellent quality retention.

Always keep a backup of your original images before resizing, especially if reducing dimensions significantly as you cannot restore lost resolution.
