Frequently Asked Questions
Why isn't my compressed file exactly 50 KB?
The tool searches for the highest quality level that still fits under 50 KB. Some images (especially very detailed ones) may end up slightly smaller than the target; a few can't be compressed to fit at all without visible quality loss.
Will optimizing my image reduce its quality?
You control the quality level. Lower settings save more space; higher settings keep quality nearly identical to the original.
Is there a limit to how many images I can process?
No. There's no limit on the number of images you can process, and it's completely free.
