Frequently asked questions
Can every image reach exactly 100KB?
The tool searches for a close result, but complex or very large images may require reducing dimensions as well.
How is the 100KB target selected?
ScanApp performs several local quality passes and keeps the closest usable result at or below the target when possible.
Is my image uploaded during optimization?
No. Every quality pass runs locally in your browser.
