For millions of Class 12 students, the Common University Entrance Test (CUET) UG 2026 is the most important exam of the year. It is the single gateway to Delhi University (DU), BHU, JNU, and other top central universities. However, the NTA portal for CUET is notoriously sensitive. A small error in the aspect ratio of your signature or a blurry category certificate can lead to your application being stuck for weeks.
As a Bank Exam aspirant, I know the frustration of technical rejections. At SarkariPixel.in, we have built a specialized ecosystem to help you clear the Technical Round of CUET in 60 seconds. In this guide, we break down the 2026 standards for CUET UG documents.
1) CUET 2026: The Technical Specification Table
The National Testing Agency (NTA) follows strict digital standards. Use this table as your checklist:
| Document Type | Format | Dimensions | File Size (KB) | Best SarkariPixel tool |
|---|---|---|---|---|
| Passport Photo | JPG / JPEG | 3.5 cm × 4.5 cm | 10 KB – 200 KB | Toolkit (NTA Photo) + Compress |
| Signature | JPG / JPEG | 4.0 cm × 2.0 cm | 4 KB – 30 KB | Toolkit (NTA Signature) + Compress |
| Class 10/12 Marksheet | PDF only | N/A | 50 KB – 300 KB | PDF → Image → Compress images → Images → PDF |
| Caste Certificate | PDF only | N/A | 50 KB – 300 KB | PDF → Image → Compress images → Images → PDF |
2) Using the Name and Date Feature for CUET
NTA often suggests that students use a photograph with their Name and the Date of Taking the Photo printed at the bottom.
The SarkariPixel Solution: You no longer need Photoshop. Our Image Resize Tool now has a built-in Text Overlay feature. Simply upload your photo, type your name and today's date, and our tool will merge them into a professional, portal-ready image.
Tip: If your CUET instructions require a specific date format (e.g., DD/MM/YYYY), type it exactly as shown on the portal.
3) The Launch Toolkit Advantage: NTA Preset
The Launch Toolkit is our most powerful tool for CUET aspirants.
- Select Preset: Choose NTA (CUET/NEET).
- Upload: The toolkit locks your dimensions to the 3.5 × 4.5 cm standard.
- KB Target: Set it to 1–50 KB for maximum quality.
- Privacy-First: Your marksheets and certificates are processed locally on your device. We never save your data. This is the Gold Standard of security.
4) Converting JPG Certificates to PDF (The 300 KB Limit)
Most students take a photo of their Caste or PWD certificate, which ends up being 4MB. The CUET portal will reject any PDF over 300 KB.
The Fix: Use our Images → PDF Tool. It converts your photo and uses smart compression to shrink the size while keeping the Tehsildar's signature and the certificate number sharp.
5) Common CUET Rejection Traps
- Selfies: Selfies distort your face. CUET requires a formal passport photo.
- Shadows on Signature: If your signature has a gray background, NTA's AI might flag it as unreadable. Use our Enhance Lab to make it high-contrast.
- Wrong Format: Uploading a JPG marksheet when the portal asks for a PDF.
Frequently Asked Questions (FAQ)
Q: Can I use a blue background photo?
A: No. CUET strictly requires a white background.
Q: My signature is 35KB, will it work?
A: No, the limit is 30KB. Use the SarkariPixel Image Compressor to hit exactly 20KB.
