How to use it
- Select a photo or signature image.
- Set a width and height under More options if your form needs exact pixels.
- Download when every check in the list passes.
Why 20 KB is hard
20 KB is a very small budget. A full phone photo has to lose most of its pixels to fit. That is normal, and the tool reduces the dimensions step by step until the file fits.
Signatures work best
A signature on plain white paper, photographed straight on in good light, compresses far better than a photo of a face. Crop tightly around the signature before you resize.
Exact pixel sizes
If your form needs a fixed size, such as a set width and height, enter it under More options. With a fixed size the tool cannot shrink the pixels, so it lowers quality instead. If it still cannot reach the limit, it tells you.
Questions
The result is a little over 20 KB. Why?
That only happens when you lock an exact pixel size that is too large for 20 KB. The results list shows a warning. Try a smaller pixel size.
Does a signature need a white background?
It helps. White paper keeps the file small and the signature clear. The tool also fills transparent areas with white.
Is anything stored?
No. Your image stays on your device and is gone when you close the page.
