Compress Images Without Losing Quality

Image compression works by reducing the amount of data stored in an image file. The goal is to make the file smaller while keeping the image visually clear. The amount of reduction depends on the original image format, dimensions, quality, and contents.

For photos, JPG and WebP compression can often produce significantly smaller files. PNG files may benefit from optimization when they contain graphics, transparency, or other elements that require lossless or near-lossless processing.
