Frequently asked questions
How do I reduce a photo to 50 KB?
Choose your photo, tap the 50 KB button (or type any size in KB), then click Resize & compress. Download the result and check its size before uploading to the form.
Is my photo uploaded to a server?
No. The photo is processed inside your browser on your own device. Nothing is sent to our servers.
What size should my photo and signature be?
It is different for every exam and form. Read the official notification for the exact limit in KB and in pixels. Many forms ask for a photo of about 20–50 KB and a signature of about 10–20 KB, but always follow your notification.
Which file format do I get?
A JPG (JPEG) file, which is accepted by almost every government form. Transparent backgrounds become white.
Why does the picture look softer after reducing the size?
A smaller KB limit needs more compression, which removes fine detail. If it looks too soft, allow a slightly larger size or choose a larger pixel size.
