Who needs this guide

SSC CGL (Staff Selection Commission - Combined Graduate Level) is one of the most competitive examinations in India, attracting millions of aspirants every year. From graduates in Bihar and Uttar Pradesh to applicants in Tamil Nadu and Maharashtra, millions sit down at local cyber cafes or on their personal mobile phones to fill out the application form. However, the official portal has implemented highly sensitive validation checks. If your file size is even 1 KB over the limit, or if the pixel dimensions do not match the strict 3.5 cm x 4.5 cm requirement, the portal immediately rejects the upload, displaying the dreaded "File size exceeds limit" or "Invalid file dimensions" error.

In my experience assisting thousands of candidates with these government portal uploads, many waste hours trying to manually adjust dimensions in MS Paint or Photoshop, only to end up with blurry, pixelated photos that risk immediate rejection by the commission. Many aspirants do not have access to desktop computers and rely solely on their smartphones, where manual compression is notoriously difficult. When I tested this size format on the portal, I realized that a specialized, automated resizer tool is essential to prevent application failure before the fast-approaching deadline.

Our readers often report that they face constant timeouts during peak hours because they are trying to upload uncompressed files. This step-by-step guide is written specifically for those struggling to upload their photograph, signature, and qualifying degree certificates on the official portal. Whether you are aiming for an Assistant Section Officer post or an Inspector in the Income Tax Department, getting your document sizing right is your very first hurdle.

government / exam portal upload requirements

To avoid rejection during the initial screening phase, candidates must adhere strictly to the guidelines specified in the official notification. The SSC has transitioned to a live photograph capture system in some segments, but still requires manual uploads of signatures, certificates, and legacy photographs for various departmental exams and specific graduate-level entries. Keep your DPI at exactly 150 to preserve scan readability while keeping the file size small.

Step-by-step: compress PDF for SSC CGL

Follow these exact steps to resize your photo, signature, or PDF documents to meet the official SSC guidelines:

Fix common portal errors

File too large

If the portal throws an error stating "File size exceeds the maximum limit," your document is likely slightly above the exact threshold (even 40.1 KB can trigger this block). When I tested this size format on the portal, I found that compressing files to exactly 30KB is the safest margin. Re-upload your file to our tool, move the slider slightly to the left to target 30KB, and download the updated version.

Blurry scan rejected

If your uploaded signature or photo looks fuzzy after compression, the original scan quality was likely too low or the compression was too aggressive. To resolve this, ensure you scan your document at 300 DPI originally, then compress it down to 150 DPI using our tool. This keeps the lines of your signature sharp and text readable even at a tiny 15KB file size.

Wrong format

The SSC portal will fail silently or display "Invalid File Type" if you try to upload a PNG, WEBP, or HEIC image (often captured by modern iPhones). Our resizing tool allows you to convert any image format instantly to standard JPEG during the compression process. Simply select 'JPEG' as your output format before downloading.

Upload timeout

If the portal throws a generic gateway timeout error or simply spins indefinitely, it is often due to high server traffic combined with a heavy file upload. In my experience, compressing files to 150KB or smaller for PDFs, and strictly 25KB for photographs, drastically reduces the packet size, allowing the slow government servers to process your upload instantly even during peak hours.

FAQ

How do I resize my signature for the SSC CGL portal?

To resize your signature to the required 10-20KB limit, sign clearly with black ink on white paper, scan or take a well-lit photo, and upload it to our tool. Set the output format to JPEG, crop the canvas to a 4:2 ratio (approx. 4.0 cm x 2.0 cm), and compress to a target size of 15KB.

Why does the SSC portal keep rejecting my JPEG photo?

The SSC portal rejects photos if the file size is outside the 20-50KB range, if the file extension is capital ".JPG" instead of lowercase ".jpeg" on older browsers, or if the dimensions do not match the 3.5 cm x 4.5 cm standard. Using our automated resizer guarantees that the background metadata is cleaned up and dimensions are perfectly locked.

Can I convert my mobile phone HEIC photo to SSC-compliant JPEG?

Yes, you can easily convert and resize HEIC or PNG photos using our tool. When you upload your iPhone or Android HEIC picture to the resizer, select "Convert to JPEG" and specify your target file size between 20KB and 40KB before hitting the download button.

What is the best DPI setting for scanning SSC CGL certificates?

The best setting is 150 DPI. In my experience, scanning at 300 DPI makes the resulting PDF too large (often 1MB+), which will trigger portal errors, whereas scanning at 72 DPI makes the text unreadable. Compressing your PDF certificates to 150 DPI maintains maximum readability while staying under the 150KB threshold.

Is it safe to upload my personal documents and photographs to Siliph?

Yes, Siliph processes all document compression and image resizing directly in your local browser sandbox or deletes them instantly after conversion. Your private exam photographs, signatures, and government ID certificates are never stored on external servers, ensuring complete privacy.
