Privacy
The page downloads its code once. After that, your files are read and written inside this browser tab: nothing is uploaded, and no request leaves the page while the work runs. An automated browser test checks the network log for this.
Frequently asked questions
Why a fixed 100 KB page?
That number shows up constantly in job and exam forms. A dedicated URL ranks for that exact intent.
Can I pick 50 KB instead?
Open “Reduce image size in KB” and type 50, or write “under 50 KB” in the box.
Does the photo leave my phone?
No. Processing stays in the browser tab.
What if it cannot reach 100 KB?
You get the smallest attempt and a failed check with the measured size.
