Image Compressor
Image Compressor is a free tool that compresses photos to a target file size (KB). Set a target size and it automatically adjusts quality and dimensions to fit under it. Great when there are upload limits — shopping mall product listings, forums, second-hand marketplaces. Images are processed 100% in your browser and never sent to a server.

FAQ
Q. Will it hit exactly that size?
It fits as close as possible under the target. It auto-adjusts quality, and if still too big, reduces the width to meet the target.
Q. Does quality drop a lot?
If the target is very small, quality goes down. Check the quality and savings shown in the result and adjust the target.
Q. Are my photos uploaded?
No. Everything is processed in your browser; images are never sent to a server.
Q. Does transparent PNG work?
The result is saved as JPG, so transparent backgrounds become white. If you need transparency, use the Background Remover too.
