UPSC Photo & Signature Size 2026 (Exact Specs)

Exact specs at a glance

The UPSC portal is strict. Files that fall outside any single dimension will be rejected without a clear explanation. Here are the official requirements in one table.

These numbers come from the UPSC Civil Services (Preliminary) notification pattern that has been consistent across recent cycles. The official notification for each recruitment year is the single authoritative source. Always cross-check these figures against the notification you downloaded from the UPSC website before submitting your application.

UPSC photo requirements in detail

The photograph requirement for UPSC Civil Services is more specific than most applicants realise on first read. Here is what each rule means in practice.

Dimensions: 200 pixels wide, 230 pixels tall

200x230 is a portrait orientation, slightly taller than it is wide. Your phone camera produces photos at 12 to 50 megapixels, which means 4000 pixels or wider. You need to resize down to exactly 200x230. Do not simply crop; you need to resize (scale down) while maintaining the correct aspect ratio, or the face will appear distorted.

Use SammaPix ResizePack to enter exact pixel values. Or use SammaPix CropRatio to first crop your photo to the 200:230 aspect ratio, then resize to the final pixel dimensions. This is the most reliable two-step sequence for passport-style photos.

File size: 20 KB to 300 KB

This is a range, not a single target. Your file must be at least 20 KB (below that it signals a corrupt or extremely low-quality image) and no more than 300 KB. A phone photo resized to 200x230 pixels will naturally land around 15 to 80 KB depending on the JPEG quality setting. If it comes out below 20 KB, re-export at higher quality. If it comes out above 300 KB (unlikely at this resolution but possible with very high quality settings), compress it down.

The sweet spot is 80 to 200 KB: good quality, well within the range, and the portal accepts it immediately. Use SammaPix Compress or Compress to 100 KB to target a specific size without guessing.

Format: JPEG only

This is the most common rejection reason that applicants do not expect. iPhones save photos as HEIC by default. When you send a photo from an iPhone to your laptop via AirDrop or email, it may arrive as a .heic file. Android phones sometimes save as PNG when you use the front camera in certain modes. UPSC rejects both.

You need a .jpg or .jpeg file. All SammaPix tools export in JPEG by default when you choose the JPEG option in the download dialog, so this is handled automatically when you process your photo through any of our tools.

Background: plain white, no shadows

A plain white background is mandatory. Off-white, cream, light grey, or any textured surface will fail manual verification even if the portal accepts the upload. Shadows on the background or the face are also grounds for rejection. The face must be evenly lit, centered, and clearly visible with both eyes open.

If your photo has a non-white background, use SammaPix Passport Photo to remove the background and replace it with white. The tool runs in your browser, processes the image locally, and produces a clean white-background portrait suitable for government applications.

UPSC signature requirements in detail

The signature upload is separate from the photograph and has completely different specifications. Many applicants get the photo right and then get the signature rejected because they treat both the same way.

How to sign correctly for UPSC

Take a plain white sheet of A4 paper. Sign your name three times in a vertical column using a black ballpoint pen. Your signature should be legible, consistent, and approximately the same across all three attempts. Choose the clearest one. Do not use a gel pen that smears, and avoid blue ink (black is the standard for government forms unless the notification specifies otherwise).

Scanning vs photographing the signature

A flatbed scanner at 300 DPI produces the cleanest result. If you do not have a scanner, photograph the signature under good natural light, hold the phone parallel to the paper (not at an angle), and ensure there is no shadow. Apps like Microsoft Lens or Adobe Scan on your phone can produce a clean flat image from a photograph.

Pixel width: 350 to 500 pixels

After scanning, the signature image needs to be cropped tightly around the signature (no large white margins) and then resized so the width falls between 350 and 500 pixels. Use SammaPix CropRatio to crop the white space, then SammaPix ResizePack to set the width to 400 pixels (a safe value within the 350 to 500 range).

File size: 20 KB to 100 KB

A signature at 400 pixels wide in JPEG format will typically be 15 to 60 KB depending on quality. Target 40 to 80 KB for the UPSC signature. If your file is below 20 KB, re-export at higher JPEG quality. If it is above 100 KB (rare at this pixel size), use SammaPix Compress to bring it into range.

Common rejection reasons and how to avoid them

Based on the most frequent issues applicants report with the UPSC online application portal, here are the eight rejection patterns and the fix for each.

• Wrong format (HEIC or PNG uploaded instead of JPEG). Fix: Open the image in SammaPix ResizePack and export it as JPEG. The download will be a .jpg file.
• Photo file is below 20 KB. Fix: Re-export the image at a higher JPEG quality. In SammaPix Compress, set the target to 80 KB to stay well above the floor.
• Photo file is above 300 KB. Fix: Use SammaPix Compress to reduce the file size. Target 100 KB to 200 KB for a clean result.
• Photo dimensions are not 200x230. Fix: Use SammaPix ResizePack. Set width to 200 and height to 230 manually. Do not rely on a general resize that preserves aspect ratio, as it may not produce exactly 200x230.
• Background is off-white, grey, or has a shadow. Fix: Use SammaPix Passport Photo to remove the existing background and replace it with a clean solid white.
• Signature image has too much white margin around it. Fix: Use SammaPix CropRatio to crop tightly around the signature before resizing. Excessive white space makes the signature appear very small relative to the frame.
• Signature is below 20 KB after compression. Fix: Re-export at higher quality. At 400 pixels wide, a JPEG at 85 percent quality will comfortably exceed 20 KB.
• Photo looks blurry at 200x230 pixels. Fix: Start with a high-resolution source image (at least 800 pixels wide). Downscaling from a larger original always produces a sharper result than upscaling from a small one.

Step-by-step: prepare your UPSC photo

Follow these steps in order. Each step takes less than 60 seconds. The entire sequence takes about two minutes.

1. 1Take or source a suitable photo. Use a recent photo taken against a white wall under natural light, or use a photo studio shot. Front-facing, both eyes open, no glasses (UPSC does not explicitly prohibit glasses but many examiners flag them during manual review). The photo should be at least 800 pixels wide in the original for best quality after downscaling.
2. 2Fix the background if needed. Open SammaPix Passport Photo. Upload your photo. The tool removes the background and replaces it with white automatically. Download the result.
3. 3Crop to the 200:230 aspect ratio. Open SammaPix CropRatio. Set the ratio to 200:230 (or equivalently 20:23). Adjust the crop box so the face is centered with a small margin above the head. Apply and download.
4. 4Resize to exactly 200x230 pixels. Open SammaPix ResizePack. Upload the cropped image. Enter 200 for width and 230 for height. Apply and export as JPEG.
5. 5Check the file size and compress if needed. Right-click the downloaded file and check its size. If it is between 20 KB and 300 KB, you are done. If it falls outside that range, open SammaPix Compress and target 100 KB. Download the result.
6. 6Verify before uploading. Open file properties and confirm: dimensions are 200x230, size is between 20 and 300 KB, and the extension is .jpg or .jpeg. Then upload to the UPSC portal.

Step-by-step: prepare your UPSC signature

The signature requires a slightly different workflow because you start from a physical document rather than a digital photo.

1. 1Sign three times on white paper. Use a black ballpoint pen on a clean plain white sheet. Keep the signature consistent. Sign only your full name (not initials unless that is your established signature). Leave space between signatures so you can identify the clearest one.
2. 2Scan or photograph the best signature. Scan at 300 DPI for the cleanest result. If using a phone camera, hold it directly above the paper with the camera parallel to the surface. Use good, even lighting without shadows. Apps like Adobe Scan will process the image to flatten it automatically.
3. 3Crop tightly around the signature. Open SammaPix CropRatio. Use freeform crop mode to remove all excess white margins. Leave only a small amount of white space around the signature text itself. Apply and download.
4. 4Resize the width to 400 pixels. Open SammaPix ResizePack. Set width to 400 pixels and let the height scale proportionally. 400 px falls within the required 350 to 500 px range. Export as JPEG.
5. 5Check the file size. A 400-pixel-wide JPEG at standard quality will usually be between 30 and 70 KB. If it is within 20 to 100 KB, you are done. If it is above 100 KB, open SammaPix Compress and target 60 KB.
6. 6Verify before uploading. Confirm width is between 350 and 500 pixels, file size is between 20 and 100 KB, and format is JPEG. Upload to the UPSC portal separately from the photograph.

Why no-upload matters for your ID photo

Most online image resizers require you to upload your photo to their server. That is standard for generic images. For a government application photograph tied to your identity, uploading to a random server means your face photo and its associated EXIF data (which may include the GPS location where it was taken, your camera model, and the exact timestamp) are stored on infrastructure you have no control over.

SammaPix processes every image in your browser. The pixel operations run in WebAssembly and JavaScript on your own device. No photo data leaves your machine. The file you download is generated locally. There is no server storing your image, no account required, and no data retained after you close the tab.

For an identity document photo intended for a competitive exam of national importance, that is the right approach.
