About

A 50 KB ceiling is the most common limit on exam and job forms for photos, thumb impressions and small scanned documents. At 50 KB a face photo can stay sharp, so the aim is to use the space well rather than crush the file.

Worked example: a scanned 1240 × 1754 px page (an A4 scan at 150 DPI) of about 600 KB is capped at 1000 px on its long side, giving 707 × 1000 px. Text on white compresses well, so a fairly high quality usually lands around 45 KB, a little under the 50 KB ceiling, without any scaling. A busy colour photo at the same size may need lower quality or a step down in pixels; the result line shows exactly what happened.

FAQ

Why does the file land a little under 50 KB?+
When the top-quality file is too big, the tool aims about 85% of the way up the range. That keeps quality high while leaving a small margin under the ceiling. The result shows the exact size.
My form says "maximum 50 KB" with no minimum. Is 30 KB fine?+
Yes. Set Min KB to 0 if you want the tool to go as small as it likes; the default 30 KB floor just keeps quality reasonable.
Can I compress a PNG or screenshot?+
Yes. Any image the browser can open is redrawn and saved as a JPG, which is what most forms ask for. Transparent areas become white.
Is my photo sent to a server?+
The tool is designed to run in your browser: the photo is cropped, compressed and saved on your device, and the page does not need an account. Close the tab and the in-memory copy is gone.
