To ensure your document is accepted by the India official platform, it must meet the following strict criteria:

The Staff Selection Commission frequently discards applications due to blurry or disproportionately sized applicant photos. By utilizing our specialized SSC formatting tool, you can effortlessly generate a pristine 3.5cm by 4.5cm portrait that stays cleanly within the mandatory 20 KB to 50 KB byte range. Certain government recruitment boards and state public service commissions require candidates to upload a single combined image file containing both their passport photograph and signature aligned vertically on a single canvas, capped strictly under 50KB or 100KB.
Our Photo & Signature Joiner allows you to upload your passport photo and signature scan independently. The engine aligns them vertically, adds an optional white divider border, enforces exact pixel width, and compresses the final combined canvas under your target size limit in one seamless step.

Select your passport photograph and signature scan in the dropzone. Provide a recent color photograph taken against a light-colored or white background without wearing spectacles or caps.
Set vertical stacking order, canvas padding, and divider line thickness. Frame your face and neck securely within the 3.5x4.5 cm bounding box to establish correct proportions.
Select 50KB or 100KB target size ceiling. Process the image to ensure the final output file falls precisely between 20 Kilobytes and 50 Kilobytes.
