Getting a photo under 20 KB
Many online application and exam forms ask for a signature under 20 KB and sometimes a photo under 20 KB too. The tool keeps the best quality that fits, shrinking the picture only when it has to.
The tool first lowers the JPEG quality step by step, then reduces the width and height only if needed, and stops at the best result that is still under 20 KB (1 KB = 1024 bytes). The photo is processed in your browser and never uploaded.
Questions
How do I reduce a photo to 20 KB?
Add the photo above. The tool picks the highest quality that fits under 20 KB and shows the final size. Download it and upload it to your form.
Is my photo uploaded?
No. Everything happens in your browser, so ID photos and signatures stay on your device.
The form still says the file is too big. What now?
Some forms count 1 KB as 1000 bytes. Choose a slightly smaller target, for example 18 KB, and try again.
