Frequently Asked Questions
How can a photo be under 20 KB?
By being smaller in pixels. A phone photo is several thousand pixels wide, while a form photo needs a few hundred. The tool reduces the size until the file fits at good quality, then shows the result.
My form asks for exact dimensions, such as 200 × 230 pixels.
Choose "Exact size (px)" in the resize section, type the width and height, then click "Fit to size": the tool keeps your dimensions and adjusts only the quality.
How do I compress a signature to 20 KB?
Sign on white paper with a dark pen, take a photo in good light and drop it here. Crop the photo close to the signature first if your phone can; less empty paper gives a sharper signature at 20 KB.
Is it safe for ID photos?
Yes. The image never leaves your device, and location and camera data are removed from the saved file.
