Who needs this guide

If you are one of the lakhs of banking aspirants across India preparing to register for the Institute of Banking Personnel Selection (IBPS) Probationary Officers (PO) recruitment, this practical guide is written specifically for you. Year after year, candidates lose precious time—and sometimes miss deadlines—because of frustrating technical errors on the application portal. The system is notoriously strict; a photo that is even 51 KB or a signature file that measures 21 KB will trigger an immediate upload failure, stalling your form submission.

When I tested this size format on the portal recently, I noticed that even a slight deviation in image dimensions or compression ratios can cause the system to drop your session entirely. Our readers often report that they face continuous "upload failed" or "file size exceeds limit" errors during the late-night hours when portal traffic spikes. This occurs because the servers struggle to process heavy, unoptimized scans, leading to session timeouts and lost progress.

Whether you are applying from a remote village using a mobile phone or sitting at a desktop in an internet café, having your digital files perfectly sized before you begin is your best defense. This guide walks you through the exact technical specifications needed for your photo, signature, left thumb impression, handwritten declaration, and category certificates, ensuring you upload them without a single system error.

government / exam portal upload requirements

The IBPS PO registration portal accepts only specific file formats and strictly defined file sizes. While photos, signatures, and thumb impressions must be uploaded in JPEG/JPG format, other mandatory supporting documents, such as category (OBC/SC/ST/EWS) or physical disability (PwBD) certificates, must be uploaded as highly compressed PDFs.

In my experience, compressing files to 150KB works best when dealing with certificate uploads, even if the absolute maximum ceiling is higher. If you upload a file too close to the limit, the portal often throws a generic gateway timeout error due to bandwidth congestion. Keep your scan DPI at exactly 150 to preserve scan readability while keeping the file size compact.

Here are the standard specifications mandated for the IBPS PO 2026 registration process:

Fix common portal errors

Even with the correct guidelines, portal glitches can happen. Here is how to quickly bypass the most common technical hurdles during submission.

File too large

If the portal rejects your file with a "file size exceeds limit" error, it means your image is either exactly on the upper limit or your device's operating system has slightly modified the file size during save operations. To fix this, re-upload the file to Siliph and set your target compression slightly lower (e.g., target 35 KB for photos instead of 49 KB).

Blurry scan rejected

When files are compressed too aggressively, text like your signature or the handwritten declaration can become pixelated. If the portal rejects the upload due to poor quality, do not increase the file size beyond the limit. Instead, re-scan the document in high resolution, crop out all empty margins/borders, and then compress it using Siliph with the DPI locked at 150 DPI.

Wrong format

If you see an "invalid file format" error, verify the file extension. The IBPS portal will not accept `.png`, `.jpeg` with double extensions, or `.tiff` files for photos and signatures. Make sure your photos end strictly in `.jpg` or `.jpeg`, and your category certificates end in `.pdf`. If necessary, use a free online converter to switch formats before compressing.

Upload timeout

If your page hangs or throws a gateway timeout error during upload, the culprit is usually a slow internet connection trying to process a file that is too close to the maximum allowed size. Our readers often report that dropping a 450 KB certificate PDF down to 140 KB instantly solves this issue, allowing the upload to complete even on unstable 3G/4G networks.

FAQ

What is the exact IBPS PO photo size limit compress threshold for 2026?

For the 2026 registration, your passport-size photograph must be between 20 KB and 50 KB in JPG or JPEG format. The dimensions should ideally be 200 x 230 pixels. Any file smaller than 20 KB or larger than 50 KB will be automatically rejected by the IBPS portal servers.

Why does the IBPS portal say "File size invalid" when my image is exactly 50KB?

Because of the way different operating systems calculate file sizes, an image showing as exactly 50 KB on your device might register as 50.1 KB on the IBPS portal. To prevent this issue, we recommend compressing your photo to a safe target range of 35 KB to 45 KB using Siliph before trying to upload.

Can I upload my handwritten declaration in PDF format?

No, the IBPS PO handwritten declaration must be uploaded strictly in JPG or JPEG format, with a file size between 50 KB and 100 KB. Category, educational, and disability certificates, however, are required to be uploaded in PDF format with a limit usually under 500 KB.

What should I do if my signature image looks blurry after compression?

If your signature looks blurry, it is usually because you scanned too much empty white space around it. Crop the signature tightly to remove unnecessary white space, scan it at 200 DPI, and then compress it to the 10 KB to 20 KB range; this ensures the signature stays sharp and readable.

How do I fix the IBPS portal gateway timeout during document upload?

This error occurs when the server takes too long to receive your file. To resolve this, compress your category PDF certificates to around 150 KB and your declaration to around 60 KB using Siliph. This reduces data transmission time, allowing successful uploads even on slow connections.
