Frequently asked questions
Can any photo be reduced to 20 KB?
Yes. If quality alone isn't enough, the tool also reduces the pixel size, so even large phone photos fit. Very detailed images will look softer at 20 KB.
My form also has a minimum size, like 10 KB. What should I do?
Use the Exam Photo & Signature Resizer, which lets you set both a minimum and a maximum size and exact pixel dimensions.
Will my image look blurry?
At 20 KB some detail is lost, especially on large photos. A signature or a small face photo usually stays clear.
What format is the result?
A JPG, which almost every form accepts.
Is my photo uploaded?
No. Everything happens in your browser.
