The Complete Guide to UPSC Photo & Signature Requirements (OTR & Exams)
Applying for any examination conducted by the Union Public Service Commission (UPSC)—including the Civil Services
(IAS), NDA, CDS, CAPF, and Engineering Services—requires navigating their One Time Registration (OTR) portal. The
UPSC employs an automated verification system to ensure that every uploaded photograph and signature perfectly
meets their strict parameters regarding file size, pixel dimensions, and image format. A minor mistake can cause
the upload process to fail immediately. Knowing exactly how to format your files is absolutely critical for a
smooth registration experience.
The Crucial "Name & Date" Rule for UPSC Photos
To ensure recent documentation and prevent impersonation, the UPSC recently introduced a strict, mandatory rule
for the candidate's passport-size photograph across all major exams. Your uploaded photo must now clearly display
your Full Name and the Date on which the photograph was taken prominently
printed at the bottom of the image. Furthermore, the date of the photograph cannot be older than 10 days from the
start of the online application process. Adding this information without squishing, stretching, or cutting off
parts of your face can be incredibly frustrating. Our tool solves this by providing an automatic toggle that
generates a clean white block with bold black text exactly at the bottom of the image, flawlessly fulfilling this
requirement in seconds.
Understanding Pixel Dimensions (350–500 px)
The UPSC dictates a precise window for image resolutions:your photograph must measure between 350 x 350 pixels
and 1000 x 1000 pixels (square). Our tool outputs at 500 x 500 px — the maximum and optimal size within this
range. Your signature must be square, between 350 x 350 pixels and 1000 x 1000 pixels.
UPSC Signature Size and Format Guidelines
Your signature must be executed on a plain white sheet of paper using a dark pen. Black ink is heavily
preferred by the commission as it scans much more clearly than blue ink. The signature should be
written in a natural, running script; completely disconnected block capital letters are generally not accepted.
The scanned signature file must be saved purely in JPG or JPEG format. Crucially, the final file size must fall
strictly between 20 KB and 300 KB. High-resolution images from modern smartphones often exceed
this limit natively, requiring careful compression before they can be successfully uploaded to the UPSC OTR
portal.
How the Auto Triple-Stack Feature Works
UPSC requires three copies of your signature stacked vertically in a single image. Our tool makes this effortless
— you only need to sign once, scan it, and upload that single image. The tool will automatically
replicate your signature three times with equal spacing and faint separator lines between each copy, producing a
correctly formatted output image at exactly 500 × 500 px within the 20–300 KB limit. There is no need to
physically sign three times on paper or stitch images together manually.
Why Use Our UPSC Resizer Tool?
Using standard smartphone image editors to compress pictures down to specific KB limits often destroys the
clarity of a signature or reduces a facial photograph to a blurry, pixelated mess. With our specialised UPSC
sizing tool, you can simply upload your raw files and let our engine handle the complex pixel resizing and file
size compression securely directly inside your browser. By automating the mandatory name and date overlay, we save
you the massive hassle of using complicated photo editing software. Best of all, because all processing is local
to your device, your private photo and signature are never sent to external servers, protecting your sensitive
personal biometric data from start to finish.
