Official UPSC One Time Registration (OTR) Photo & Signature Guide
The Union Public Service Commission (UPSC) requires all candidates appearing for the Civil Services Examination (CSE / IAS), NDA, CDS, CAPF, and Engineering Services to upload compliant photos and signatures on the One Time Registration (OTR) portal (upsconline.nic.in).
According to official UPSC guidelines: Candidates must upload a recent passport-sized photograph and signature in JPG/JPEG format. Both files must be between 20 KB and 300 KB. Furthermore, the photograph must not be more than 10 days old, and the candidate's face should occupy at least 75% of the frame.
Wyori's UPSC compression engine takes care of these technical hurdles automatically. It preserves facial structure, removes noise, and compresses your file into a safe 90KB payload that uploads in milliseconds.
