Who needs this guide

This guide is specifically designed for banking aspirants across India who are filling out the IBPS Probationary Officer (PO) 2026 application form on the official IBPS exam portal. Whether you are applying from a mobile phone in a rural area or from a desktop in a cyber cafe, navigating the strict document upload limits set by the Institute of Banking Personnel Selection can be highly frustrating.

Our readers often report that after spending an hour filling out their academic and personal details, the portal abruptly throws a "File size exceeds limit" or "Invalid dimensions" error when they try to upload their photo, signature, left thumb impression, or hand-written declaration. If your scans are generated from a modern smartphone camera, they are likely between 2MB and 6MB. The IBPS system will reject these large files instantly.

When I tested this size format on the portal, I realized that many applicants mistakenly try to force-upload raw images or use generic image editors that ruin the file's legibility. This detailed technical guide will walk you through preparing every single required document to ensure your registration is accepted by the portal on your very first attempt without risking application rejection.

government / exam portal upload requirements

The IBPS PO 2026 official notification enforces strict parameters for all uploaded files. While photographs and signatures must be uploaded in JPEG/JPG format, supporting certificates (such as category, EWS, or disability certificates) must be submitted in clear, readable PDF formats under specific file size ceilings.

Below is the official breakdown of the file sizes and dimensions required for the 2026 recruitment cycle:

Fix common portal errors

"File too large" or "Size exceeds limit"

This is the most common issue. If you capture a photo with a 64MP smartphone camera, the image size will be massive. Pass the photo through our resizer tool to scale it down specifically to 30KB. For PDF certificates, keeping the DPI at exactly 150 helps preserve scan readability while keeping the total file size well below the 500KB cap.

"Blurry scan rejected" / Poor Legibility

If you compress your signature too much, the black lines will smudge, making it look like a black blob. The IBPS automated verification system will reject this during scrutiny. Always use a high-contrast scan (black ink on plain white paper) and aim for the upper threshold of the limit (18KB instead of compressing it down to 10KB).

"Invalid File Format" Error

The portal will reject your signature or photograph if it is saved in PNG, HEIC, or WEBP formats. Make sure your final download from the compressor tool is strictly saved as `.jpg`, `.jpeg`, or `.pdf` (for multi-page certificates). Simply renaming the file extension from `.png` to `.jpg` manually will corrupt the file; you must use a proper converter tool.

Upload Timeout / Gateway Error

If the portal throws a generic gateway timeout error, especially during the last few days of registration, it is usually because the portal servers are overloaded with heavy files. Try compressing your scan further to 140KB for certificates or 25KB for photos. Smaller files upload faster, preventing connection drops on slow broadband connections.

FAQ

What is the exact photograph and signature size limit for IBPS PO 2026?

For the IBPS PO 2026 exam registration, your candidate photograph must be between 20 KB and 50 KB in JPG/JPEG format. Your signature must be uploaded separately, and its file size must fall strictly between 10 KB and 20 KB. Failing to meet these specific size ranges will block you from advancing to the fee payment page.

Why does the IBPS portal reject my signature file even if it is under 20KB?

The portal does not just verify the file size; it also checks the physical dimensions of the image. Your signature image must be close to the preferred dimensions of 140 x 60 pixels. also, if you write your signature in CAPITAL letters or use a blue gel pen that bleeds through the paper, the automated system might flag it as invalid.

Can I upload my left thumb impression and hand-written declaration in PDF format?

No, the left thumb impression and hand-written declaration must be uploaded strictly in JPG or JPEG format. The thumb impression must be between 20 KB and 50 KB, while the hand-written declaration must be between 50 KB and 100 KB. PDF format is only accepted for category, educational, or PwD certificates if prompted by the portal.

How do I fix the "Upload session timed out" error on the IBPS website?

This error occurs when your network upload speed is slow or when the file you are uploading is too large for the system to process before the session expires. To resolve this, compress your documents to the lower end of their accepted limits (e.g., 22KB for photographs or 12KB for signatures) using our fast compression tool, clear your browser cache, and try uploading again.

What should I do if my compressed certificate PDF becomes unreadable?

If your PDF certificate is blurry after compression, it means the quality ratio was set too low. Re-run your original document through the Siliph compressor, keeping the DPI setting at 150 and targeting a size of 150KB to 200KB. This ensures that the seals, signatures, and roll numbers on your certificates remain sharp and readable for the verification officers.
