Every year, lakhs of banking aspirants across India face immense anxiety during the Institute of Banking Personnel Selection (IBPS) Probationary Officers (PO) registration process. The application form requires uploading a passport-sized photograph, a handwritten declaration, a left thumb impression, and a signature within strict file size parameters. If your files deviate by even a single kilobyte, the automated portal script blocks your progress, showing cryptic and frustrating error screens. This technical guide explains exactly how to prepare and compress your files to pass the IBPS online gatekeeping system seamlessly.

Who needs this guide

This guide is prepared specifically for bank job candidates across India who are filling out the IBPS PO 2026 online registration form. Whether you are operating from a high-speed broadband connection in Bengaluru or a mobile-only network in a rural village in Uttar Pradesh, uploading your registration documents requires exact technical specifications. Many candidates do not have access to professional scanner software or Adobe Photoshop, relying instead on mobile cameras to capture their physical photographs and signatures.

When you snap a picture of your physical photo or signature with a modern smartphone, the resulting file size is typically between 3MB and 6MB. When you attempt to upload this file directly to the IBPS server, the site throws a stubborn "file size exceeds limit" error or simply freezes without warning. If you try to downscale the image using generic online compressors, you risk losing the legibility of your signature, which can lead to application rejection during the document verification stage. This guide will show you how to preserve 150 DPI readability while shrinking file sizes down to the exact kilobyte limits required.

In my experience helping thousands of banking candidates through our support channels, we often see applicants paying hefty fees to cyber cafe operators just to get their files resized. This article empowers you to compress your own files securely on your mobile phone or laptop for free, ensuring your private identity documents are processed safely without third-party exposure.

government / exam portal upload requirements

The IBPS portal uses automated scripts that scan uploaded files for specific dimensions, format, and file size. If any of these parameters do not match their predefined validation rules, the system rejects the file. For instance, uploading a signature in capital letters or a photo with a dark background can cause issues, but the primary blocker is almost always the file size.

Based on the official notification for IBPS PO 2026, here is the breakdown of the document upload parameters:

When I tested this size format on the portal, I realized that many standard mobile scanners output files in PNG format by default. Since the IBPS exam portal only accepts JPG or JPEG formats, converting and compressing your files correctly is critical to avoiding immediate form validation failures.

Step-by-step: compress PDF for IBPS PO

If you have compiled your scans into a PDF file or need to extract and compress your individual passport photos and signatures to match the required specifications, follow these practical steps. These instructions apply to both Android/iOS mobile devices and desktop browsers.

Fix common portal errors

File too large

If the IBPS portal displays a red error box reading "File size exceeds maximum limit," your image is likely still hovering above 50KB for photos or 20KB for signatures. Even a file that is exactly 20.1KB for a signature will trigger a system-wide block. Re-upload your image to Siliph, slide the compression quality bar down by an additional 10%, and download the newly optimized file.

Blurry scan rejected

Many generic online compressors aggressively strip image resolution to force the file under a certain size limit, resulting in a blurry mass of pixels that the exam validators will reject. Keep DPI at exactly 150 to preserve scan readability while keeping the file lightweight. Siliph uses smart vector preservation algorithms, ensuring that your text lines remain sharp even at ultra-low kilobyte sizes.

Wrong format

If you see an "Invalid file format" warning, you are likely attempting to upload a PNG, WEBP, or PDF file into an upload slot that only supports JPG/JPEG. If you have a PDF scan of your documents, run it through our converter tools to extract individual high-resolution JPG images before attempting to submit them to the registration portal.

Upload timeout

Our readers often report that the IBPS portal throws a generic gateway timeout or "network connection lost" error when they try uploading files. This usually happens in areas with poor 4G/5G coverage because the portal's server times out while receiving large payloads. If the portal throws a generic gateway timeout error, try compressing the scan further to 140KB for certificates or ensuring your photos are on the lower limit (e.g., 25KB) to reduce the upload bandwidth required.

FAQ

How do I fix the IBPS PO photo size limit compress error on a smartphone?

To fix the smartphone upload error on the IBPS portal, do not upload raw camera images which are typically 3MB to 5MB. Instead, open your browser, access the Siliph resizer tool, upload your photo, and set the target limit strictly between 20KB and 50KB. Download the output JPG and upload it directly from your phone's download folder.

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

If your signature appears blurry, it means the compressor stripped too much image data. To prevent this, ensure your original photo is taken in bright, natural light with black ink on plain white paper. Use Siliph's smart compression tool to keep DPI at exactly 150 while lowering the size to 15KB, preserving maximum line contrast.

Can I upload a PDF instead of a JPG for the IBPS PO photo and signature?

No, the official IBPS registration portal only accepts JPG or JPEG formats for the photo, signature, thumb impression, and handwritten declaration. If you have these files saved as a PDF document, you must convert the PDF pages into JPG images first, compress them to the proper size limits, and then perform the upload.

Why does the IBPS portal throw a gateway timeout error during document upload?

This error occurs when the portal's server takes too long to receive your file, which is common if you are uploading large uncompressed files over slow mobile networks. To resolve this, compress your photograph to 25KB and your signature to 15KB; the smaller payload sizes will transmit instantly even on weak internet connections.

What is the correct scanner DPI setting to meet the IBPS PO document upload size limit?

When scanning your documents with a flatbed scanner, set the resolution to exactly 150 DPI or 200 DPI. Setting the scanner resolution higher (like 300 DPI or 600 DPI) creates massive files that exceed the IBPS PO document upload size limit, requiring heavy compression that can degrade the scan quality.
