To register for the exam, you must meet the strict IBPS PO photo size limit compress your files to 20–50KB for photos and 10–20KB for signatures. If your files are too large, you can easily [compress PDF for IBPS PO](/exam-photo-resizer) or resize your JPEG files for free using Siliph online tools.

When I tested this size format on the portal during the last application cycle, I noticed that even a single kilobyte over the limit causes the IBPS server to throw a generic error. This guide will walk you through preparing all your files perfectly so you do not lose your registration fee or miss the deadline.

Who needs this guide

This step-by-step guide is written specifically for banking aspirants across India who are filling out the IBPS PO (Probationary Officers) 2026 application form. Every year, thousands of candidates from both rural areas and major metro cities face major roadblocks during the online registration process. The Institute of Banking Personnel Selection (IBPS) uses automated image validation software that instantly rejects files if they do not match the exact pixel dimensions and kilobyte limits specified in the official notification.

If you are using a mobile phone to scan your documents, your photo will likely be around 2MB to 5MB, which is far too large for the portal. When you attempt to upload these raw scans, you will see frustrating errors like "file size exceeds limit" or "invalid file dimensions." This guide helps you resize, compress, and format your passport photograph, signature, left thumb impression, and hand-written declaration to the exact standards required for successful upload.

In my experience helping candidates fix these validation errors, attempting to manually rename extensions or using low-quality offline paint applications often results in pixelated, illegible images that can get your application rejected during the scrutiny phase. Following the precise compression steps outlined below ensures your files remain crystal clear while staying safely under the portal's strict limits.

government / exam portal upload requirements

The IBPS PO registration portal has strict, non-negotiable size limits and dimension guidelines for every document you upload. Uploading a blurry image or a file in the wrong format will prevent you from moving forward to the payment gateway. Based on the official IBPS PO 2026 notification guidelines, here are the exact upload specifications you must meet:

  • Passport Photograph: Must be a recent passport-style color picture, taken against a light-colored (preferably white) background. The size must be between 20KB and 50KB, with preferred dimensions of 200 x 230 pixels.
  • Signature: Must be signed on white paper with black ink. The size must be between 10KB and 20KB, with preferred dimensions of 140 x 60 pixels. Note that signatures written in CAPITAL LETTERS are strictly rejected by the system.
  • Left Thumb Impression: Must be taken on white paper with blue or black ink. The file size must be between 20KB and 50KB, with dimensions of 240 x 240 pixels (200 DPI preferred).
  • Hand-written Declaration: Must be written in English on white paper with black ink. The file size must be between 50KB and 100KB, with preferred dimensions of 800 x 400 pixels.
  • Category or Disability Certificates: If you are uploading supporting documents, such as an SC/ST/OBC/PwD certificate, these must be uploaded in PDF format with a file size limit usually not exceeding 500KB.

    Step-by-step: compress PDF for IBPS PO

    Whether you are using a desktop computer or your mobile phone web browser, preparing your documents for the IBPS PO portal is straightforward when using Siliph. Follow these exact steps to compress and format your files perfectly:

  • Select your tool: Open your browser and handle to the Siliph tool. For images like your photo and signature, use the exam photo resizer. For certificate files, use the PDF compressor tool.
  • Upload your file: Click on the "Upload" button and select the document, photo, or signature scan from your device's gallery or local storage folder.
  • Set target file size: Choose the compression level or manually input your desired target size. For instance, set your photo target to 40KB (safely between 20KB and 50KB) and your signature to 15KB (safely between 10KB and 20KB). Keep DPI at exactly 150 to preserve scan readability.
  • Verify the live preview: Check the instant preview generated by Siliph. Ensure that your name on the signature or the details on your certificate are perfectly readable and not blurry. Our readers often report that keeping the target slightly below the absolute maximum (e.g., 45KB for photo) guarantees a successful first-time upload.
  • Download the compressed file: Click on the "Download" button to save the optimized file directly to your device. Keep track of where the file is saved (usually your "Downloads" folder).
  • Upload to the IBPS portal: Log into your IBPS PO 2026 application dashboard, handle to the document upload step, select your newly compressed file, and click upload. The portal should display a green checkmark indicating successful validation instantly.

    • Fix common portal errors

    File too large

    If the portal displays a "File size exceeds limit" error, it means your file is even slightly over the maximum threshold (such as 50.1KB for a photo). In my experience, compressing files to 40KB for photos and 15KB for signatures works best to bypass strict automated checkers that calculate file sizes differently than your operating system.

    Blurry scan rejected

    This happens when you compress a file too aggressively using poor third-party tools. If your hand-written declaration or certificate details become fuzzy, re-upload the high-quality original scan to Siliph, and set the compression scale to a slightly higher quality percentage. Always use clean black ink on pure white paper to maximize contrast.

    Wrong format

    IBPS only accepts JPG or JPEG formats for photos, signatures, and thumb impressions, while supporting certificates must be uploaded as PDFs. If you uploaded a PNG or a HEIC file from an iPhone, the system will reject it. Convert your file to JPEG or PDF before attempting to compress and upload.

    Upload timeout

    If the portal throws a generic gateway timeout error or hangs mid-upload, try compressing the scan further (e.g., to 140KB for PDF certificates or 35KB for photos). Large files take too long to process on heavily loaded servers, especially on the last few days of registration when millions of aspirants are trying to submit their forms simultaneously.

    FAQ

    Can I upload my signature in capital letters on the IBPS PO portal?

    No, the IBPS portal strictly prohibits signatures written in capital or block letters. If you upload a signature in capital letters, your application will be rejected during verification. You must sign in a running, cursive handwriting style using black ink on a blank white sheet of paper, compress it to 10-20KB, and then upload it.

    What should I do if my hand-written declaration exceeds 100KB?

    If your hand-written declaration scan exceeds 100KB, you can easily use the Siliph resizer tool to compress the JPEG. Set your target compression size to approximately 80KB to ensure that the writing remains completely legible while staying safely below the maximum 100KB limit required by the IBPS PO portal.

    Why does the IBPS portal say "File size exceeds limit" when my file is exactly 50KB?

    Different computer systems calculate kilobyte sizes differently (using binary vs. decimal systems). If your photo is exactly 50KB, the IBPS portal's server may read it as 50.1KB and reject it. To avoid this, always aim for a safe buffer zone, compressing your passport photo to around 40KB and your signature to 15KB.

    Can I convert my Category Certificate PDF to a smaller size without losing readability?

    Yes, you can easily compress your SC, ST, OBC, or PwD certificates down to under 500KB using the Siliph PDF compression tool. Our smart compression algorithm reduces the file size by removing metadata while preserving the high visual quality of the printed text and official stamp details.

    Is it safe to upload my Aadhaar card or signature scans to Siliph for compression?

    Absolutely — siliph values your data privacy and security. When you upload your personal documents, photos, or signature files for compression, they are processed securely over HTTPS and automatically deleted from our secure servers within a short time window. No personal data is ever shared or stored permanently.
