Who needs this guide

If you are an Indian citizen applying for the Staff Selection Commission Combined Graduate Level (SSC CGL) exam, you have likely encountered strict document validation errors. Our readers often report that trying to upload signatures, category certificates, or disability proofs on the official portal results in cryptic system failures. The portal demands highly specific file sizes, and even a minor deviation of 1 KB will trigger an immediate upload failure. This is especially frustrating when you have spent hours filling out academic details only to have the session time out because of a bloated file.

When I tested this size format on the portal, I realized that many applicants lack access to professional desktop image editors. Candidates from rural areas or smaller towns often visit internet cafés, spending anywhere from ₹50 to ₹100 just to get their signatures scanned and compressed to the correct size. This guide provides a free, self-reliant way to format your own files on a mobile phone or computer in less than a minute.

In my experience, compressing files to 150KB works best for PDF documents, while signatures need to sit strictly between 10 KB and 20 KB. Having helped thousands of aspirants handle this process, I have documented the exact parameters, steps, and troubleshooting techniques required to bypass the portal's validation gatekeepers without compromising legibility.

government / exam portal upload requirements

The SSC CGL application requires different documents to be formatted in different ways. While the photograph is captured live via the official app or portal webcam, your signatures and supporting certificates must be uploaded manually as static files. Failing to match the required byte range, file type, or pixel dimensions will cause the server to drop your connection or display an invalid format prompt.

Here are the standard file parameters defined in the official SSC CGL notifications:

Below is a quick reference table detailing how to prepare your documents before attempting the upload process on the portal:

Follow this step-by-step procedure to resize and compress your documents or signatures. This process is fully compatible with both mobile web browsers and desktop systems.

Fix common portal errors

Even with resized files, backend system errors can sometimes occur. Here is how to resolve the most frequent errors that applicants face on the portal.

File too large

If you see a "File size exceeds limit" error despite keeping your file close to the threshold, it means the server's internal parser is reading the file slightly differently. Try compressing the scan further to 140KB for PDFs, or 14 KB for signature images. This safety buffer avoids triggering automated server blockages.

Blurry scan rejected

When you aggressively compress files, text can become pixelated. This will lead to rejection during physical document verification. Keep DPI at exactly 150 to preserve scan readability. At this resolution, text remains perfectly clear even when the final PDF file size is squeezed down to 100 KB.

Wrong format

The SSC portal accepts only specific formats. It will reject a `.png` signature file or a `.docx` certificate scan. Double-check your file extension. If you accidentally saved a file as a PNG, upload it back to our tool to export it cleanly as a standard `.jpg` file.

Upload timeout

During the last few days of the registration window, millions of candidates hit the server at once. If the portal throws a generic gateway timeout error, your network might be dropping packets because of the high server load. Try reducing your file sizes slightly beneath the upper limit to ensure faster data transfer over congested cellular networks.

FAQ

What is the official size limit for the SSC CGL signature upload?

Your signature file must be between 10 KB and 20 KB in JPG or JPEG format. The portal will reject any signature file that is even 9.9 KB or 20.1 KB in size. Use our specialized resizer to target an ideal output size of exactly 15 KB to guarantee acceptance on the government / exam portal.

How can I convert a certificate photo into an SSC CGL compliant PDF?

You can snap a clean picture of your certificate using your phone, upload it to our conversion tool, and export it as a PDF. Make sure you set the file limit constraint to under 200 KB before downloading the file to prevent upload errors on the portal.

Why does the portal say "Dimensions invalid" for my signature?

The official system requires signature images to be exactly 4.0 cm wide by 2.0 cm high. When you use the Siliph tool, you can set these exact pixel/centimeter constraints along with the file size target so that both parameters align with the official guidelines.

Can I upload a black-and-white PDF certificate for the application?

Yes, greyscale or black-and-white PDFs are highly recommended. Scanning in color increases the file size unnecessarily without adding any functional value. Scanning in greyscale keeps DPI at 150 and ensures the final file stays well within the 200 KB limit.

What should I do if my document still fails to upload during peak hours?

If the server is highly congested, compress your files further to around 120 KB to 140 KB. Lighter files bypass gateway bottlenecks much easier. Alternatively, try uploading your documents during off-peak hours, such as early in the morning or late at night.
