Who needs this guide

This step-by-step manual is designed specifically for banking aspirants across India submitting their applications for the Institute of Banking Personnel Selection (IBPS) Probationary Officers (PO) recruitment exam. When you are rushing to complete your registration before the final deadline, encountering a "file size exceeds limit" error on the official IBPS portal is extremely frustrating.

Our readers often report that they struggle to get their scanned documents down to the precise parameters demanded by the central exam portal. Many candidates do not have high-end scanner setups and rely on mobile cameras or local cyber cafés. When you snap a high-resolution photo with a modern smartphone, the image size is typically 3MB to 8MB—vastly larger than the strict caps. This guide will help you prepare and downsize your passport-size photo, signature scans, left thumb impression, handwritten declaration, and reservation certificates without losing legibility.

IBPS portal upload requirements

The official IBPS selection board maintains strict algorithmic filters on their registration gateway. If your uploads exceed the defined parameters by even a single byte, the portal will reject the file or freeze during the final submission. To avoid rejection, you must strictly follow the specifications below.

Required Document Specifications Table

In my experience, compressing files to 150KB works best for PDF certificate uploads, while targeting 40KB for the photograph and 15KB for the signature guarantees a successful, hassle-free upload on the first attempt.

Step-by-step: compress PDF for IBPS PO

Follow these exact operational steps on your mobile phone or desktop to resize, format, and compress your application documents using Siliph's web utility:

Fix common portal errors

File too large

If the portal displays a generic red error message saying "File size exceeds limit," your upload is likely sitting right at the borderline (e.g., 50.1KB for a photograph). To solve this, do not guess: re-run the file through the Siliph tool and set your target threshold specifically to 40KB for photographs and 15KB for signatures to give the server-side validator an undeniable safety margin.

Blurry scan rejected

When users compress files aggressively to meet size demands, text elements or facial features often become pixelated or unreadable, leading to manual verification rejection. Keep DPI at exactly 150 to 200. Avoid utilizing low-quality mobile apps that apply heavy lossy compression; our Siliph tool uses advanced vector preserving scripts to maintain visual lines while shedding hidden metadata bloat.

Wrong format

Many applicants try to upload signature files in PNG, HEIC, or PDF formats, triggering an immediate "Invalid File Format" warning. The IBPS photo, signature, thumb impression, and declaration must be saved strictly in `.jpg` or `.jpeg` formats. Use Siliph's conversion option to output the final file directly into standard JPEG before trying to submit.

Upload timeout

If the portal throws a generic gateway timeout error, try compressing the scan further to 140KB. Slow broadband or cellular connections in rural or semi-urban regions frequently drop connection packets when sending large certificate PDFs over 300KB. Reducing the certificate size to roughly 140KB ensures the upload is fast enough to fit within the active session window.

FAQ

What happens if my IBPS PO signature is exactly 21KB?

If your signature file is exactly 21KB, the automated IBPS portal script will immediately reject the file because the maximum specified limit for signatures is 20KB. You must compress the signature to a range between 10KB and 20KB. Passing a file of 15KB ensures absolute compatibility.

Can I use a blue ink signature for IBPS PO 2026 registration?

No, the official IBPS guidelines state that the signature must be done on white paper using a black ink pen. Rejections and cancellation of candidatures are common when applicants submit blue ink signatures, so please stick to black ink and scan it properly.

How do I fix the 'File size exceeds limit' error for the handwritten declaration?

To fix this error, you need to compress the handwritten declaration image to fall between 50KB and 100KB. Use the Siliph resizer to scale down the image resolution to 800 x 400 pixels while keeping the compression ratio high enough to read your handwriting.

Why does the IBPS portal log me out during the PDF upload process?

This issue occurs because of server-side session timeouts when trying to upload heavy files over a sluggish internet connection. By compressing your certificate PDFs down to around 150KB, you allow the files to upload rapidly, keeping your session secure.

How can I verify that my compressed PDF is safe to upload?

Before uploading to the IBPS portal, right-click your file on desktop or tap 'File Details' on mobile to check that the size is well within the official limits. Open the file to ensure the text, your face, or the signature lines are clearly visible without heavy pixelation.
