Frequently asked questions
Can it make an image exactly 100KB?
The tool aims to get as close as practical while staying at or below the target. Exact byte-for-byte matching is not guaranteed because image encoders work in quality steps.
Why may dimensions get smaller?
If lowering JPEG quality is not enough to reach a very small target, the tool gradually reduces dimensions to meet the limit.
Is the file uploaded anywhere?
No. Compression happens in your browser on your device.
