How to prepare your left thumb impression
- The guideline asks for the left thumb. Take the impression on white paper using black or blue ink, pressing evenly so it isn't blurred or smudged.
- Scan it, or capture an image of it in good light.
- Open the CCC Thumb Impression Resizer and choose the image.
- Zoom so the impression fills most of the 170:132 frame.
- Process it, check the results list and download the JPG.
What the tool handles — and what it can't
- Exact size of 170 × 132 pixels, cropped rather than stretched
- File size within 5–20 KB where the image allows it
- JPG/JPEG output with 150 DPI written into the file
It can't make a smudged or faint impression clearer. If it's hard to see, take it again.
If the file is below 5 KB
Plain images compress very well, so a small thumb impression can come out under 5 KB even at the highest quality. ExamPhotoFixer keeps that highest-quality version and shows a warning instead of padding the file or adding artificial noise.
You can still download it. If the application website rejects it for being too small, start again from a sharper, higher-resolution original — more real detail produces a larger file.
Frequently asked questions
Is 170 × 132 the width or the height?
The first number is the width. The thumb impression should be 170 pixels wide and 132 pixels tall.
What does 96–200 DPI mean?
DPI (also called PPI) is a value stored inside the image file. It doesn't change the pixel size. ExamPhotoFixer writes 150 DPI, which is inside the stated 96–200 DPI range.
If my file meets these values, will my form be accepted?
Meeting these technical values doesn't guarantee your application will be accepted — the exam body decides. Always check the current official instructions before you upload.
