Who needs this guide

This guide is prepared specifically for banking aspirants across India who are actively filling out their online application forms for the Institute of Banking Personnel Selection (IBPS) Probationary Officers (PO) recruitment drive for 2026. Every year, lakhs of graduates from cities like Patna, Nagpur, Coimbatore, and Lucknow try to upload their scanned credentials on the official IBPS application portal. The application portal uses rigid automated validation scripts that instantly reject any file that is even 1 KB over the stipulated limits.

Our readers often report that when they try to upload their freshly scanned documents, the portal returns the highly frustrating "file size exceeds limit" or "invalid image dimensions" error. Many candidates try using default mobile camera settings, which produce high-resolution JPEG files ranging anywhere from 3 MB to 8 MB. When I tested this size format on the portal, I noticed that even a slightly oversized 51 KB photo file gets rejected instantly without any clear instructions on how to correct the problem.

If you are a student operating from a mobile phone, a local cyber cafe, or your personal laptop, this guide will save you hours of confusion. We will show you exactly how to scale down your files to meet the official 2026 registration requirements without losing essential scan quality.

government / exam portal upload requirements

To ensure your IBPS PO application is not flagged or rejected during the initial screening process, your scanned files must comply with exact dimensions and file size limits. The portal accepts JPEG/JPG formats for photos and signatures, while larger certificates must be in PDF format.

In my experience, compressing files to 150KB works best for PDF certificates, as it strikes the perfect balance between clear text legibility and low bandwidth overhead. The table below outlines the exact requirements specified for the 2026 IBPS PO registration cycle.

Fix common portal errors

File too large

If the portal rejects your file with a "file size exceeds limit" pop-up, it means your file is still hovering slightly above the threshold (e.g., 50.2 KB). Re-run the file through Siliph and manually enforce a lower target output of 35 KB.

Blurry scan rejected

Keep DPI at exactly 150 to preserve scan readability when saving certificates as PDFs. If you set the resolution too low, the system might accept the file size but the human verifiers will reject your application later because the text is unreadable.

Wrong format

Ensure you do not upload files with `.png`, `.heic`, or `.webp` extensions. The IBPS system only registers `.jpg` or `.jpeg` for photos and signatures. Use Siliph to export your files directly into the correct format.

Upload timeout

If the portal throws a generic gateway timeout error, try compressing the scan further to 140KB for PDF certificates. Oversized uploads often cause the server to drop connections during high-traffic registration days.

FAQ

What is the exact IBPS PO photo size limit compress requirement?

The official 2026 IBPS PO notification dictates that your scanned passport photograph must be between 20 KB and 50 KB. The format must be JPG or JPEG, and the pixel dimensions should ideally be 200 x 230 pixels for optimal rendering.

Why is my signature rejected on the IBPS portal?

Your signature will be rejected if it is smaller than 10 KB, larger than 20 KB, or signed using blue ink or capital letters. Ensure you use black ink on white paper and compress the file to exactly 15 KB using Siliph before uploading.

Can I upload a PDF certificate larger than 500KB on the IBPS portal?

No, the IBPS registration portal strictly enforces a 500 KB limit for all uploaded category or physical disability certificates. If your scanned PDF exceeds this, you must run it through a compression tool to avoid upload failure.

How do I fix the gateway timeout error during document upload?

Gateway timeout errors occur when the IBPS server is overloaded or struggling to receive heavy files. To bypass this, compress your documents slightly below the limit (for example, target 140 KB instead of 500 KB for PDFs) to ensure rapid, error-free transfers.

Is it safe to compress my personal exam documents online using Siliph?

Yes, compressing your files on Siliph is entirely safe. The compression process is secured using industry-standard protocols, and your sensitive personal details are never stored on external servers, keeping your competitive exam registration private.
