If your form needs a signature resize for SSC, start with a clear signature on plain paper. Match the current notice for the signature dimensions, set the required KB range, and download the result in JPG format. Open the saved file once before uploading it because the form receives the exported file rather than the editor preview.
Choose the SSC signature size in KB
Most SSC notices specify the file size in KB. The same notice can also list the signature width, height, format, or resolution. Use the numbers in the notice for the form you are completing because SSC settings can change between recruitment cycles. The tool’s quick choices are starting points and should not replace the current notice.
Several SSC application notices have asked for a scanned signature in JPG or JPEG format within a 10 KB to 20 KB range. Some notices also provide physical dimensions for the signature. Check the notice for your exact recruitment before selecting the final output.
| Portal detail | Working option | What to verify |
|---|---|---|
| File size | 10 KB to 20 KB when the notice gives this range | Check whether the notice gives a minimum, a maximum, or both. |
| Dimensions | Use the width and height shown in the notice | Do not assume the working profile fits every SSC form. |
| File format | JPG or JPEG when the notice asks for it | Open the exported file and check its format. |
| Signature source | A clear scan or phone image with visible ink | Check that every important stroke remains readable. |
Resize an SSC signature to 10 KB or 20 KB
When the notice allows 10 KB to 20 KB, choose a value inside that range instead of selecting the nearest button without checking. Use the signature resize 10 to 20 KB option only when the notice gives that range. If the notice gives only a maximum, do not force the file toward the smallest possible size because heavy compression can erase thin strokes. The tool can work as an SSC signature compressor when the file is too large, but compression should stop when the writing starts to lose clarity.
After reducing the file, zoom in on the saved signature. Broken letters, muddy edges, or missing joins sometimes mean the source image needs improvement. Lowering the quality again can make the file smaller, but it can also make the signature difficult to read.
Prepare the signature in JPG format
Use JPG when the SSC notice asks for JPEG or JPG. PNG or another file type is not automatically a substitute because the upload field can check the format as well as the file size. After export, open the image and confirm that the signature strokes are still visible against the background. This keeps the signature JPG in the format expected by the application.
Cropping blank paper around the writing is different from changing the writing itself. Keep the original strokes, joins, and proportions. If glare, blur, or a cut off line affects the scan, use a clearer source because an enhancer cannot recreate a mark that was never captured. Confirm the signature JPG format and the signature in JPG format before completing the JPG signature resize step.
Keep every important signature stroke readable
The output can meet the signature dimensions and still be difficult to use if thin writing disappears after compression. Compare the first and last strokes, small dots, joins, and any narrow lines with the original scan. If a mark is missing, the problem is with the source or the processing strength, not with the KB number alone.
A clearer scan or phone image is safer than trying to recreate a broken line. Keep the handwriting unchanged and use the smallest adjustment that leaves the existing signature easy to recognise.
Check the downloaded SSC signature before upload
The image inside the editor is only a preview. Open the downloaded file on your device because the SSC form receives that file. Check these four details before upload:
- It is in JPG or JPEG format when the notice asks for it.
- Its file size falls within the stated KB range.
- Its dimensions match the notice.
- Every signature stroke is still readable.
Keep the original signature scan separately until the application is submitted. If the first export is too small or unclear, the original lets you create another version without repeatedly compressing the same reduced file.
SSC signature resize questions
How do I resize a signature for an SSC application?
Upload a clear scan or phone image of your handwritten signature. Read the current SSC notice, match its dimensions and KB range, then export the file in the requested format. Open the saved file before uploading it.
What is the SSC signature size in pixels and KB?
There is no single signature pixel size for every SSC application. The current notice can specify the KB range, physical dimensions, pixel dimensions, or all of them. Use the instructions for your exact recruitment instead of assuming that the working profile is universal.
How do I resize a signature to 10 to 20 KB?
Set the file size within the 10 KB to 20 KB range when the notice gives that range. Check the signature after compression because the 10 KB to 20 KB signature size range can still make thin strokes unclear when the file is reduced too much. If the writing loses clarity, start again with a clearer scan.
Does SSC require a signature JPG format?
Use JPG or JPEG when the SSC notice asks for it. After downloading, open the file and confirm the extension, file size, dimensions, and visible signature. Check the signature upload size shown by the notice rather than assuming that another format will be accepted simply because it opens on your device.
PassportPhotoBox prepares and compresses the signature file. It is independent software and does not issue SSC forms or decide whether an application will accept the upload. Use the current SSC notice as the final source.
Official SSC sources
SSC signature instructions can change between recruitment notices. The official SSC website and the current notice for the selected recruitment should always control the final dimensions, file format, and KB range used for upload.
