Almost every online exam form rejects a photo or signature that is the wrong size. A phone photo is usually 2–5 MB, while forms ask for something like 20–50 KB at a fixed pixel size. The table below collects the sizes for the exams people apply to most, and each row opens a detailed guide and the free Photo & Signature Resizer already set to that size.

Sizes change from one notification to the next. Always compare with the official notification of the exam you are applying for — it is the final word, and every value in the resizer can be changed to match it.

How to get any photo to the right size

  1. Open the Photo & Signature Resizer and pick your exam under "What is this for?".
  2. Choose your photo or a scan of your signature. Crop it so your face (or the signature) fills the frame.
  3. For a signature, tick "Clean the paper" so the background turns pure white and the ink stays dark.
  4. Download. The file comes out at the exact pixel size and inside the KB range, ready to upload.

Everything runs inside your browser, so your photo and signature are never uploaded to any server.

Frequently asked questions

Find your exam in the table above and open its guide. If your exam is not listed, use the size printed in its official notification - type the width, height and KB limits into the Photo & Signature Resizer under 'My own size'.

Many forms reject it. The resizer keeps the file inside the minimum and maximum together, so it is not too small either.

No. The resizing happens inside your browser and your photo never leaves your device.

Yes, but resize it separately for each one, because the pixel size and KB limits differ from exam to exam.
