Thumb Impression Photo Resize in KB

Make a clear impression

1. Press the thumb gently on a stamp pad. Do not use too much ink or the ridges will merge.
2. Press it once inside a box on plain white paper. Roll slightly, do not slide.
3. Let the ink dry before you move the paper.

Resize it step by step

1. Take the picture in even light from straight above, or scan the paper. Avoid shadows.
2. Open the Photo Editor and crop close around the impression with a little white space.
3. Open Photo & Signature Resizer and select the cropped image.
4. Enter the maximum KB, and the minimum KB if the form gives one. Enter width and height in pixels only if the form lists them.
5. Create the JPEG and check the KB shown. Download it.
6. Open the file and zoom in. The ridge lines should still be visible, and the file should be a JPEG if the form asks for JPG.

What the tool does to the shape

When you enter both width and height, the tool fits the whole image inside that frame and fills the empty space with white. It does not stretch the picture. In our test, a 1600 x 1200 pixel test image of 692.5 KB, set to 20 to 50 KB and 300 x 400 pixels, came out as a 300 x 400 pixel JPEG of 24.19 KB, with white bars above and below because the frame was taller than the picture. Crop your image to the same shape as the frame first if you do not want bars.

If the file is rejected

• Too large: lower the maximum KB or reduce the pixel size a little.
• Too small: raise the minimum KB, or start from a sharper picture.
• Blurred: retake it in better light. A smaller file cannot add detail.
• Wrong type: export JPG, not PNG or WebP, unless the form says otherwise.
