How it works
KadiTools runs a binary search on the encoder quality to find the highest quality that stays under your target. If even the lowest reasonable quality is too big, it scales the image down step by step until it fits. You get the best-looking file that respects the limit.
FAQ
Why did my image get smaller in dimensions?
Your target was too small for the original resolution, so KadiTools reduced the dimensions as well as the quality.
Is 1 KB = 1000 or 1024 bytes?
1024 bytes, which is what most upload forms and operating systems use. KadiTools targets slightly under the limit to be safe.
