Who needs this guide

Every year, hundreds of thousands of banking aspirants across India face immense technical hurdles while filling out the Institute of Banking Personnel Selection (IBPS) Probationary Officers (PO) online application form. While preparing for rigorous sections like Quantitative Aptitude and Reasoning is stressful enough, candidate registration often presents an unexpected roadblock: the file upload step. When uploading scanned copies of your passport photo, signature, left thumb impression, or handwritten declaration, the IBPS portal routinely throws frustrating validation errors.

Our readers often report that after spending hours scanning their physical documents, they are repeatedly blocked by warnings such as "File size exceeds limit" or "Invalid dimensions." This occurs because modern smartphone cameras capture high-resolution images that easily exceed 3 MB to 5 MB. The IBPS servers, built to handle massive concurrent traffic from lakhs of candidates, enforce strict file size caps of 20–50KB for photos and 10–20KB for signatures to preserve server bandwidth and ensure smooth processing. If your file size is even a fraction of a kilobyte over the limit, the system rejects it automatically.

In my experience, attempting to manually resize these images using general smartphone gallery crops or generic paint programs frequently results in pixelated, blurry files that the portal's automated validation engine will discard. This step-by-step technical guide is designed specifically for these candidates—whether you are applying from a fast home broadband connection or a remote regional cyber cafe with limited internet speed. By using Siliph's dedicated tools, you can compress, resize, and strip bloated metadata from your images in seconds, ensuring your documents match the exact specifications required for the IBPS PO 2026 application without compromising on legibility.

government / exam portal upload requirements

To ensure your IBPS PO 2026 registration progresses without hitches, you must adhere strictly to the guidelines specified in the official IBPS PO notification. The portal validation script analyzes both the file weight (in kilobytes) and the physical pixel dimensions of the uploaded image files. If there is a mismatch in either parameter, the upload will fail instantly.

Here are the critical file requirements for the IBPS PO exam portal:

  • Passport Photograph: Must be a recent, colored passport-style photo taken against a light-colored, preferably white, background. The acceptable size limit is strictly 20 KB to 50 KB, and the preferred dimensions are 200 x 230 pixels (or 4.5 cm x 3.5 cm).
  • Candidate Signature: Must be signed on white paper with a black ink pen. The acceptable size limit is 10 KB to 20 KB, and the preferred dimensions are 140 x 60 pixels. Note: Signatures written in capital/block letters are strictly rejected by the screening committee.
  • Left Thumb Impression: Must be taken on white paper with blue or black ink. The acceptable size limit is 20 KB to 50 KB, with preferred dimensions of 240 x 240 pixels (3 cm x 3 cm) scanned at 200 DPI.
  • Handwritten Declaration: Must be written by the candidate in English on white paper with a black ink pen. The size limit is 50 KB to 100 KB, with dimensions of 800 x 400 pixels (10 cm x 5 cm) at 200 DPI.
  • Category/PwD Certificates: If you are claiming reservation under SC/ST/OBC/EWS or PwD categories, any requested certificate uploads should ideally be under 500 KB and formatted as optimized PDF files.

    • Below is a quick reference table for preparing your application assets:

    Step-by-step: compress PDF for IBPS PO

    Preparing your files to match the IBPS requirements does not require complex software like Photoshop. Follow this clear, tested step-by-step workflow using Siliph's free online tools to resize your photographs, signatures, and certificates on both desktop and mobile devices.

  • Capture and Crop Your Raw Image: Place your photograph or signature paper on a flat, well-lit surface. Take a clear photo using your smartphone. Crop out any unnecessary background space (such as the table or surrounding blank paper) using your phone's built-in editor. Trimming the excess canvas is the most effective first step to drastically lower file size.
  • Work through to the Resizing Tool: Open your web browser on your phone or computer and go to IBPS PO PDF Compressor. If you are preparing caste or PwD certificates in PDF format, work through to the fallback link at /compress-pdf instead.
  • Upload Your File: Tap on the 'Select Files' button or drag and drop your cropped photo or signature directly into the designated drop zone. Siliph's secure cloud server processes files instantly without storing your personal data permanently.
  • Adjust the Target Size and Settings: Once your file is uploaded, the tool will display its current size. Adjust the quality slider or input your target weight. For the passport photograph, set the slider to target approximately 35 KB to 40 KB (comfortably within the 20–50KB range). For the signature, set your target weight to exactly 15 KB. When I tested this size format on the portal, aiming for a mid-range target (like 15KB) rather than the absolute maximum of 20KB yielded the highest success rate because it avoids marginal byte overflows.
  • Check the Live Preview: Before final compression, verify the live preview window. Ensure that text in the signature or handwritten declaration is sharp and easily readable. Keep DPI at exactly 150 to preserve scan readability while keeping the physical footprint of the file under control. Siliph's compression algorithm automatically removes invisible EXIF camera metadata, which normally bloats phone captures by up to 250KB, without degrading actual image quality.
  • Download and Re-Upload to IBPS: Click 'Compress' and download the processed image or PDF to your local device. Log in to your candidate dashboard on the IBPS portal at ibps.in. Go to the document upload section, select your newly compressed file, and upload it. The portal will display a clear thumbnail preview. If the preview displays smoothly without generating errors, your document meets all internal server validation standards and you can proceed to fee payment.

    • Fix common portal errors

    File too large

    If the IBPS portal throws an error stating "File size exceeds limit," your image is likely just over the 50KB or 20KB threshold. Even a size of 20.1KB for a signature will trigger a failure. In my experience, compressing files to 150KB works best for certificates, while keeping signatures strictly between 12KB and 17KB using Siliph avoids these strict border checks.

    Blurry scan rejected

    If you compress your files too aggressively, the text of your handwritten declaration or signature can become pixelated. This can lead to application rejection during manual scrutiny. To fix this, do not drop the quality slider below 60%. Keep DPI at exactly 150 to 200 during scanning to balance sharpness with a tiny file footprint.

    Wrong format

    Many modern smartphones capture images in HEIC or WEBP formats by default. The IBPS portal will not recognize these extensions and will display a generic "Invalid File Format" warning. Always run your images through the Siliph tool, which converts files strictly to standard JPEG/JPG format during the compression process.

    Upload timeout

    If the portal throws a generic gateway timeout error, try compressing the scan further to 140KB for PDFs or 35KB for photographs. Underperforming regional internet connections or slow servers at the IBPS end struggle to upload heavier files. A smaller file payload ensures your connection completes the transfer before the session expires.

    What should I do if my signature size is slightly above 20KB?

    If your signature file is over 20KB (even at 20.1KB), the IBPS PO portal will block your upload. To resolve this, upload your signature image to the Siliph resizer, set the target file size to 15KB, and download the compressed JPEG. This ensures your file is well within the 10–20KB limit, stripping out invisible metadata while retaining critical visual clarity.

    Why is the IBPS portal rejecting my handwritten declaration even though it is under 100KB?

    This rejection usually happens due to incorrect aspect ratio dimensions or because you signed in block letters. The handwritten declaration must be written in running handwriting, and the physical dimensions should be close to 800 x 400 pixels. Use the Siliph resizer tool to adjust both the pixel dimensions and the file size to keep it within the required 50–100KB window.

    Can I upload my category or OBC certificate in PDF format on the IBPS PO portal?

    Yes, category certificates, disability certificates, and other supporting documents must be uploaded in PDF format on the IBPS PO portal where requested. Ensure the PDF file is saved at a low resolution and does not exceed 500KB. You can use the Siliph PDF tool to compress your certificate down to an optimal size while preserving seal and signature legibility.

    How do I fix the "Invalid image dimensions" error on the photo upload screen?

    This error occurs when the pixel height and width of your photograph do not match the expected 200 x 230 pixels layout. When uploading your picture to Siliph, check the resolution settings, crop the image to a standard 4.5 cm x 3.5 cm ratio, and then compress the final file to roughly 35KB before attempting another upload on ibps.in.

    What DPI should I use to scan my left thumb impression for the IBPS application?

    You should scan your left thumb impression at exactly 200 DPI. Scanning at higher resolutions like 300 or 600 DPI will result in huge file sizes that exceed the 50KB limit, while scanning below 150 DPI will smudge the ridges of your thumbprint, potentially causing verification issues later during the exam or interview stages.
