How to use: Exam photo & signature resizer
- 1Find the photo and signature rules in your exam notice (usually a section called "Guidelines for scanning and upload").
- 2Add your photo or signature. A phone camera picture is fine.
- 3Enter the size the way the notice gives it, pixels or cm/mm with a DPI, and the smallest and largest file size in KB.
- 4Choose "Fill the frame" for photos or "Keep everything" for signatures, so no letters are cut off.
- 5Press "Make it fit", check the preview, and download the JPG.

These numbers come from recent notices and change from year to year. Each exam page above starts with them filled in, and you can edit any value before you press the button.
Why resolution (DPI) matters
Many notices give the size on paper, such as 3.5 × 4.5 cm or 50 × 20 mm, together with a resolution such as 100 or 200 DPI (dots per inch). The two together fix the pixels: 3.5 × 4.5 cm at 200 DPI is 276 × 354 pixels, while the same size at 100 DPI is only 138 × 177.
Phone photos are usually saved at 72 or 96 DPI and thousands of pixels wide, so a file shrunk to 20 KB can still claim to be 40 cm wide. Choose Centimetres or Millimetres, type the size and DPI from your notice, and the tool sets the matching pixels and writes the DPI into the JPG. The result message tells you the pixel size and the printed size it measures.
Photo or signature: which framing?
Fill the frame scales the photo until there are no empty edges and trims the extra evenly from the sides or top and bottom. That suits face photos, which are taller than they are wide.
Keep everything fits the whole picture inside the box and fills the rest with white. Use it for signatures, thumb impressions and declarations, where cutting off a letter would get the form rejected.
Taking a good photo of your signature
Sign with a black pen on plain white paper, in good daylight, and hold the phone straight above it. Crop loosely around the signature in your gallery app first if there is a lot of desk in the picture. Then choose White paper, dark ink: grey shadows from indoor light become clean white, and the ink stays sharp.
Frequently asked questions
Why does the form reject my photo even though it looks fine?
Portals check the file type (almost always JPG), the size in pixels or centimetres, the resolution and the file size in KB before anyone looks at the picture. If any of them is off, the upload fails or the form is rejected later. This tool sets all of them at once.
My signature is only 4 KB but the form wants at least 10 KB. What do I do?
Small images are naturally light. The tool saves at top quality and, if the file is still under the minimum, tops it up with blank metadata. The picture is unchanged and the file opens normally everywhere.
Is 1 KB 1000 or 1024 bytes?
Portals differ, so the tool aims for a size that passes both readings. A 20–50 KB rule gives a file of at least 20,480 bytes and at most 50,000 bytes.
Are my photos sent anywhere?
No. Everything runs in your browser, so your photo, signature and thumb print never leave your phone or computer.
