UPSC Photo & Signature Resizer
The UPSC one-time registration portal expects a square 350 × 350 pixel image for both the photograph and the signature, with the file size between 20 KB and 300 KB. Because the frame is square and most phone photos are not, the smart centre-crop matters here: it trims the sides symmetrically instead of compressing your face horizontally. This page opens with the UPSC specification already applied. Upload, reposition with drag and zoom until the head and shoulders are centred, and export. The 300 KB ceiling is comfortable, so the encoder keeps the quality high and the photograph stays crisp for the interview board. Every step runs inside your own browser using the Canvas API and Web Workers — no upload, no server, no account.
