Who needs this guide

If you are an aspiring candidate preparing for the SSC CGL (Staff Selection Commission Combined Graduate Level) exam, you know how crucial every single step of the registration process is. Months—sometimes years—of rigorous study can be jeopardized by a single technical error on the ssc.gov.in portal. Thousands of candidates from urban centers to remote villages across India find themselves locked out of the application process simply because their scanned photos, signatures, or academic PDFs do not match the highly specific, automated server requirements.

In my experience assisting hundreds of candidates from Bihar, Uttar Pradesh, and Maharashtra, many get stuck because the new live-capture feature or photo upload rules on the updated portal are incredibly sensitive. I have seen students pay ₹50 to ₹100 at local cyber cafes just to get their signatures or category certificates scaled down to the correct KB limit. Many of our readers report that after paying their fees, the portal throws a generic gateway timeout error because their uploaded files are too heavy for the server to process during high-traffic hours.

This guide is written specifically for those who want to skip the frustrating loop of upload errors, avoid paying unnecessary cyber cafe fees, and prepare their documents independently using a smartphone or PC. We will focus on getting your passport-sized photographs, signatures, and essential PDF certificates compressed to the perfect size with absolute clarity, ensuring your form is accepted on the first attempt.

government / exam portal upload requirements

The SSC CGL registration portal has extremely rigid criteria. If your file exceeds the specified limit by even a fraction of a kilobyte, or if its pixel dimensions are slightly off, the system will instantly reject it. Understanding these exact numbers beforehand prevents repetitive failures.

Here are the critical document specifications required during the form-filling process:

Step-by-step: compress PDF for SSC CGL

When I tested this size format on the portal, I realized that many candidates fail because they compress their files down to the absolute boundary. For example, compressing a photo to exactly 39.9 KB can trigger an error if the portal\'s server recalculates the byte size differently. It is always safer to target the middle of the allowed range—such as 30 KB for photos and 15 KB for signatures.

Fix common portal errors

Even with the right file sizes, minor technical glitches on the SSC site can disrupt your submission. Here is how to handle them based on real applicant feedback.

File too large

This is the most common error message. If the portal displays this despite your file being close to the limit, it means the portal's server-side script is interpreting the binary file size strictly. If the portal throws a generic gateway timeout error, try compressing the scan further to 140KB for PDFs, or 25KB for photos. Staying 10% below the maximum limit bypasses these strict validation loops.

Blurry scan rejected

Many candidates make the mistake of over-compressing their files using cheap online tools, making the text unreadable. Our readers often report that their application was rejected during physical verification because their OBC or EWS certificate was blurry. Keep DPI at exactly 150 to preserve scan readability during the PDF compression process. This ensures the digital signatures of the issuing authority and government seals remain sharp.

Wrong format

If you see an "Invalid File Format" error, double-check your file extension. The SSC portal will not accept `.png`, `.webp`, or `.tiff` files. Simply renaming a file from `photo.png` to `photo.jpg` does not change its internal encoding and will trigger a server error. You must use a dedicated converter tool like Siliph to properly convert and format the document structure.

Upload timeout

During the final week of registration, millions of students access the SSC servers simultaneously, causing severe lag and timeout errors. To solve this, first ensure your internet connection is stable. Second, reduce your file sizes to the lower end of the allowed bracket (e.g., 22 KB for photos). Smaller files require fewer server resources and upload much faster, drastically reducing the chance of a timeout.

FAQ

What is the official photo size limit for SSC CGL?

According to the official notification, your scanned passport-sized photograph must be between 20 KB and 40 KB. It must be in JPG or JPEG format, with dimensions of approximately 3.5 cm width by 4.5 cm height, and taken against a light-colored, preferably white, background.

Why does the SSC portal reject my JPEG photo upload?

The portal usually rejects photos if the file size is outside the 20-40 KB range, if the file extension is incorrect (such as PNG or WEBP), or if the face coverage is less than 80%. Ensure your ears are visible, you are looking directly at the camera, and your photo has been resized correctly using a reliable compressor.

How do I compress my caste certificate PDF to under 300KB?

You can upload your scanned caste certificate to the Siliph PDF compressor, choose the "Standard Compression" option, and download the optimized PDF. Our system preserves the clarity of the seal and signatures of the Tehsildar or issuing authority while keeping the file size well under the 300 KB limit.

Can I resize my signature to 10-20KB on a mobile phone?

Yes, you can easily do this on any Android or iOS smartphone. Simply take a clean, well-lit picture of your signature, upload it to the Siliph image resizer, set the target output size slider to 15 KB, and download the compressed JPEG file directly to your phone.

Is it safe to upload my official government certificates to Siliph?

Absolutely. Siliph respects your privacy and utilizes secure, end-to-end encryption. All uploaded documents, photos, and PDFs are processed automatically and deleted from our servers shortly after conversion, ensuring your personal data remains completely safe.
