What “maximum KB” means
This tool treats 1 KB as 1,000 bytes and verifies the finished file. It targets a file at or below your ceiling, not an exact byte count. Very small limits may require smaller dimensions or may be impossible without unacceptable quality.
Output limitations
The compressor outputs JPEG and may change color profiles or transparency. Compression does not promise removal of every metadata structure; use the dedicated metadata-removal tool when that is part of your sharing review. HEIC input is not supported.
