Who needs this guide

As an applicant filing the Staff Selection Commission Combined Graduate Level (SSC CGL) 2026 exam application, you are likely navigating one of the most competitive and strictly monitored portal uploads in India. Hundreds of thousands of graduates from Tier-1 to Tier-3 cities face frustrating technical barriers during the online application process. When I tested this size format on the portal, I noticed that even a minor mismatch of 1 KB or a slight variance in pixel density immediately prompts an "upload failed" warning, leaving candidates locked out of their accounts.

In my experience, compressing files to 150KB works best for certificates, while keeping photos strictly between 20KB and 40KB ensures instant acceptance on the server. If you are a candidate applying from a rural region with slow internet connectivity, or if you are attempting to complete the registration from a mobile browser, preparing your documents offline or through a fast online optimizer is absolutely crucial. Our readers often report that the server times out or throws encrypted system errors when the uploaded file sizes exceed standard limits, even by a tiny margin.

Whether you are trying to upload your caste certificate, high school marksheet, or passport-sized photograph, this step-by-step guide is designed to help you prepare your files perfectly. You will learn the precise dimension requirements, compression rules, and the exact steps to clear portal validation checks on your very first try.

government / exam portal upload requirements

The Staff Selection Commission has standardized file rules across all central administrative posts. To avoid rejection, you must prepare each digital scan exactly according to the administrative specifications.

Fix common portal errors

Even with correct sizes, several server-side bugs can prevent successful registration. Use these proven technical fixes to bypass portal issues.

File too large

When the portal displays a generic "File too large" message even though your properties show 40KB, the server's validation script might be reading the uncompressed metadata or thumbnail cache. To fix this, convert your photo using Siliph to clear any hidden exif headers and drop the size to 25KB. Keeping the file slightly below the upper threshold prevents validation mismatches on congested web nodes.

Blurry scan rejected

Reducing file size aggressively can sometimes ruin legibility, leading to manual application rejection during scrutiny. Keep DPI at exactly 150 to preserve scan readability while resizing. Avoid compressing the same image repeatedly. Always start with the original high-resolution camera snap and run the compression algorithm once directly down to the target 20-40KB range.

Wrong format

Many applicants try uploading photos saved with `.png` or `.webp` extensions directly, triggering formatting errors. The SSC CGL registration form strictly requires genuine `.jpg` or `.jpeg` formats. If you have a PDF certificate or a PNG photo, pass it through Siliph's converter tool to ensure it is output as a standard JPEG before attempting to upload.

Upload timeout

A common symptom of bad network architecture on state and central servers is the connection resetting mid-upload. If the portal throws a generic gateway timeout error, try compressing the scan further to 140KB (if uploading a PDF) or 22KB (if uploading a photo). Smaller files transfer much faster, minimizing the transmission window and preventing the gateway from killing your session.

Why does the SSC CGL portal show an invalid dimensions error?

This error happens because the server scans the pixel width and height in addition to the file weight. For the photograph, ensure your dimensions are exactly 3.5 cm by 4.5 cm (or 320 x 412 pixels). Adjusting the dimensions prior to compressing ensures that the government / exam portal validators recognize the file structure correctly.

How can I compress my SSC CGL certificate to under 300KB?

You can easily compress your educational or category certificates using our online compressor. Simply drop your scanned document into the PDF utility, choose the standard compression option, and let the algorithm reduce the scale while maintaining text legibility. In my experience, keeping files around 140KB to 150KB prevents both blurry visual outputs and portal upload timeouts.

What is the official photo size limit for SSC CGL 2026?

The official notification states that the passport-sized photograph must be between 20KB and 40KB in JPEG/JPG format. Beyond that, the photograph must be recent, taken without spectacles or a cap, and both ears must be clearly visible. Submitting files outside these margins will lead to automated rejection during the preliminary processing phase.

Can I upload a PDF instead of JPEG for my photo on the exam portal?

No, the photo upload section on the exam portal strictly mandates JPEG/JPG files. PDFs are reserved for auxiliary certificates like caste, disability, or high school transcripts in specific state-level recruitments. If your photo is currently formatted as a PDF, convert it to JPEG first before compressing it down to the required size limit.

Why is my compressed photo blurry on the application preview?

This occurs if you compress an already low-resolution image or use low-grade resizing engines. To resolve this, take a clear photo with a smartphone camera under good lighting, upload the high-quality original, and use Siliph to scale it down. Keeping the image crisp while hitting the 20-40KB benchmark will make sure your identity is verified without issues.
