Questions
Why do forms ask for 20 KB?
Many government, exam and job portals still limit photo and signature uploads to 10–50 KB. A small, cropped image fits easily.
It still looks blurry. What can I do?
Crop the photo to just the face or signature first with Crop image, so the 20 KB goes to the part that matters.
Are my files uploaded?
No. The tool runs inside your browser, and the page is blocked from sending data anywhere. You can check by turning off your internet connection: it keeps working.
