How to Compress Photo and Signature for SSC CGL, CHSL & Govt Job Portals

Applying for SSC CGL, CHSL, MTS, or State PSC exams? Government application servers strictly reject uploads if your passport photo is not between 20KB-50KB (3.5cm x 4.5cm) or your signature is not between 10KB-20KB (4.0cm x 2.0cm). Here is how to compress and crop both files to the exact byte count in seconds on your mobile or PC without blurriness.

5 Easy Steps

Open Compress Image Studio and Upload Passport Photo

Pro Tip: Ensure the photo has a plain white or light background and both ears are clearly visible as per SSC notification rules.

Set Exact Size Target to 45 KB

Select the 'Target Size' mode and enter 45 KB. This guarantees your file stays well above the 20KB minimum and under the 50KB strict ceiling.

Pro Tip: Avoid setting the slider to 50KB exactly; 45KB leaves safe overhead for portal file size calculators.

Verify Dimensions (3.5 cm x 4.5 cm / 350x450 px)

Verify that the aspect ratio matches the required 3.5cm width by 4.5cm height. Use the built-in Crop tool if needed to center your face.

Pro Tip: SSC rules require the face to cover 70-80% of the photograph area.

Compress Your Signature to 15 KB (10KB - 20KB Rule)

Upload your scanned signature (black or blue ink on clean white paper). Set Target Size to 15 KB and confirm dimensions of approximately 4.0cm x 2.0cm.

Pro Tip: If the paper background looks grayish, use our Image Adjust filter to increase brightness and contrast for pure white background.

Download JPG and Upload to the SSC Portal

Frequently Asked Questions

What are the exact SSC CGL photo and signature size rules?

Passport Photo must be in JPEG/JPG format, between 20 KB and 50 KB, with dimensions of approximately 3.5 cm (width) x 4.5 cm (height). Signature must be in JPEG/JPG format, between 10 KB and 20 KB, with dimensions of 4.0 cm (width) x 2.0 cm (height).

Why does the SSC portal say 'File size is not within specified limit'?

This happens if your photo is even 1 byte over 50 KB (e.g. 50.2 KB) or under 20 KB. By setting iEditPDF's exact target to 45 KB for photos and 15 KB for signatures, you ensure your file is safely within the acceptance window.

Can I do this directly on my mobile phone?

Yes. iEditPDF works 100% in mobile browsers (Chrome, Safari, Firefox). You can snap a photo with your phone camera, crop, and compress immediately without downloading any app.

Does the SSC accept PNG format photos?

No. The official Staff Selection Commission portal strictly enforces JPG/JPEG files. iEditPDF automatically exports standard compliant JPEG format.
