How Image Compression to a Target File Size Works
JPG and WebP images can usually be compressed by reducing encoding quality. If that is not enough and dimension reduction is allowed, the tool can gradually reduce image dimensions to get closer to your selected KB or MB target. PNG is lossless, so very small targets may require dimension reduction or a different output format.
The requested target is a goal rather than a promise. Some images cannot reach an extremely small file size without severe visual loss. When that happens, the tool reports the result honestly instead of pretending the target was achieved.
