Many government recruitment boards, civil service examinations (such as UPSC, SSC, state PSC), and banking KYC portals require applicants to upload a single composite image containing their passport photograph on top and their signature directly below it. Upload portals typically reject applications if the composite does not meet exact dimensional requirements (such as 300x400 pixels) or exceeds strict file size limits (often under 50KB).

Manually arranging and resizing these images in general-purpose desktop editors requires calculating canvas pixel ratios, aligning bounding boxes, and compressing output files repeatedly to meet file size caps. This tool automates the entire process in your browser.

### Worked Example: UPSC / SSC Application Format (300x400 px) Consider preparing candidate credentials for an online civil service registration: - **Source inputs:** A 300x300 px color passport portrait and a separate 300x120 px crop of a signed white paper. - **Target dimensions:** UPSC/SSC standard preset of 300 px width by 400 px height. - **Canvas composition:** The canvas fills with a solid white background (#FFFFFF). The candidate photograph is positioned in the upper 72% of the canvas (300 px wide by 288 px high). A clean subtle divider guideline (#E2E8F0) is rendered at y = 288 px. - **Signature positioning:** The candidate signature occupies the lower 28% of the canvas (inset 10 px, y = 293 px, width 280 px, height 102 px). - **Exported result:** A single composite 300x400 px JPEG file encoded at 92% quality with a final file weight under 45 KB, perfectly compliant with portal upload rules.

### Local Privacy Guarantee Government identity documents and personal signatures must remain confidential. This tool performs all canvas layout, scaling, and JPEG encoding locally on your computer with zero server uploads.
