To complete your online application form on the official exam portal, you must adhere to the IBPS PO photo size limit compress guidelines: your passport photograph must be between 20KB and 50KB, and your signature must be between 10KB and 20KB. If your scanned documents exceed these strict file size limits, you can compress PDF for IBPS PO quickly and free online with Siliph's optimization tools.

Who needs this guide

If you are an aspiring banking professional preparing to submit your application for the IBPS PO (Probationary Officers) 2026 recruitment drive, this guide is written specifically for you. Every year, lakhs of candidates across India face unexpected technical hurdles when uploading their passport-sized photographs, scanned signatures, left-thumb impressions, and handwritten declarations to the official Institute of Banking Personnel Selection (IBPS) registration portal. The application window is highly time-sensitive, and even a tiny variance in kilobyte size can cause the portal's system to reject your files or trigger a frustrating "file size exceeds limit" error.

In my experience helping candidates work through these strict online portals, the document upload phase is where a majority of applicants get stuck. You may have spent hours filling out your basic details, educational qualifications, and bank preferences, only to find that your modern smartphone camera has saved your signature scan as a high-resolution 3MB file. The IBPS system, designed to parse millions of forms efficiently, will reject any signature that is even 1KB over the absolute 20KB ceiling.

When I tested this size format on the portal recently, I noticed that generic online image compressors often degrade the quality to the point where the candidate's face or signature becomes unreadable. This can lead to your application being flagged or rejected altogether during the pre-examination document verification stage. Our readers often report that keeping details clear while compressing is highly stressful. This guide provides a direct, foolproof way to meet all specifications without sacrificing quality.

government / exam portal upload requirements

To successfully register for the IBPS PO 2026 exam, you must upload four primary files. Occasionally, if you are claiming reservation or physical disability benefits, you may also need to upload educational certificates or caste category certificates in a PDF format under 500KB. The automated validation script on the IBPS portal is highly sensitive to file size, extension format, and image dimensions.

Below are the official document requirements you must prepare before clicking the upload button:

  • Passport Photograph: Must be a recent passport-style color picture. It is best to take this against a white or very light-colored background to ensure your features are clear. The file size must be strictly between 20KB and 50KB, with recommended dimensions of 200 x 230 pixels.
  • Signature Scan: Written on white paper with black ink. The size must be strictly between 10KB and 20KB, with recommended dimensions of 140 x 60 pixels. Do not sign in capital letters.
  • Left Thumb Impression: Stamped on white paper with blue or black ink. The size must be between 20KB and 50KB, with recommended dimensions of 240 x 240 pixels.
  • Handwritten Declaration: Written in English on white paper with black ink. The size must be between 50KB and 100KB, with recommended dimensions of 800 x 400 pixels.
  • Here is a quick-reference table outlining the specifications:

    DocumentTypical limitTip
    Passport Photo20KB - 50KBKeep DPI at exactly 150 to preserve scan readability while keeping size low.
    Signature Scan10KB - 20KBCrop tightly around the signature to eliminate useless white margins and drop file size.
    Left Thumb Impression20KB - 50KBEnsure the ink ridges are clearly visible; do not over-compress or smudge the ink.
    Handwritten Declaration50KB - 100KBMust be in your own handwriting and written in running text (not all-caps).
    Category Certificate (PDF)Under 500KBIf the portal throws a generic gateway timeout error, try compressing the scan further to 140KB.

    Step-by-step: compress PDF for IBPS PO

  • Prepare and crop your original files: Take a clear photograph of your physical document (photo, signature, thumb impression, or declaration) under bright, natural light using your smartphone. Use your phone's built-in gallery tool to crop out any surrounding background elements like table surfaces or shadows.
  • Upload to Siliph: Open your browser and go to the IBPS PO PDF Compressor tool page. Click on the upload box to select the file from your gallery or drag and drop your file directly into the upload zone.
  • Set your target file size: For your passport photo, set the target size to 35KB. For your signature scan, set the target to 15KB. For a handwritten declaration, select 75KB. Choosing the midpoint ensures you remain safely within the portal's limits.
  • Verify the preview quality: Check the live preview rendered on your screen. When I tested this size format on the portal, I found that maintaining a clear view of facial features and signature lines is crucial. Make sure there is no severe pixelation or blur.
  • Download the optimized file: Once you are satisfied with the preview, click "Compress & Download." The tool will quickly process the image or PDF and save the optimized version to your device's "Downloads" folder.
  • Re-upload to the IBPS portal: Log into the official IBPS PO 2026 portal, work through to the document upload tab, select your newly compressed files, and click upload. Double-check the preview displayed on the portal to confirm it appears correctly.
  • Fix common portal errors

    File too large

    If the IBPS portal displays a red error box stating "File size exceeds the allowed limit," your document is likely on the borderline or slightly above the cap. Even if your computer properties show exactly 50KB, server-side math can occasionally read it as 50.1KB. Re-upload the file to Siliph, slide the compression target slightly lower (e.g., to 40KB for photos or 14KB for signatures), and try again.

    Blurry scan rejected

    If you receive a notification that your signature or photo is too blurry to process, the initial image was likely captured in low light. In my experience, compressing files to 150KB works best for certificates, but for tiny files like signatures, the source photo must be sharp. Re-take the scan near a bright window, ensure your camera auto-focuses on the ink, and compress it again.

    Wrong format

    If you get an "Invalid file format" error, verify that your images are saved with a `.jpg` or `.jpeg` extension. If you took the photo with an iPhone, it might be saved in HEIC format, which the IBPS website cannot read. Use our online tool to convert and compress the file directly into a compliant JPEG format before uploading.

    Upload timeout

    If the portal throws a generic gateway timeout error, it typically points to a slow internet connection handling an unoptimized file, or heavy server traffic on the IBPS site. Try compressing your scanned PDF or JPG files further—compressing your declaration down to 60KB and certificates down to 140KB can significantly lower the upload bandwidth and prevent the connection from dropping.

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

    No, signatures written entirely in CAPITAL LETTERS are strictly rejected by the IBPS. You must sign in a natural, running hand on white paper using black ink, scan it, crop it tightly, and then compress it to between 10KB and 20KB before uploading to avoid rejection.

    What should I do if the IBPS portal rejects my thumb impression?

    If the portal rejects your left thumb impression, check both the ink clarity and the file size. Ensure you have used a clear blue or black ink pad, that the file is saved as a JPG/JPEG, and that you have compressed it with Siliph to sit comfortably within the 20KB to 50KB range.

    Is a white background mandatory for the IBPS PO photograph?

    While a white or very light-colored background is highly recommended in the official IBPS notification to ensure maximum clarity, it is not an absolute system block. However, to eliminate any chance of manual rejection during document verification, we strongly recommend using a photo with a white background compressed to 35KB.

    What are the exact dimensions for the handwritten declaration?

    Your handwritten declaration should be written in English on white paper with black ink. The recommended dimensions are 800 x 400 pixels (which corresponds roughly to a 10 cm x 5 cm box), and the final file size must be kept strictly between 50KB and 100KB.

    Why does the IBPS site show an error even when my file is 49KB?

    This occurs because the IBPS server converts kilobytes using binary math where 1KB equals 1024 bytes, whereas some operating systems show sizes in decimal math. In my experience, compressing your photograph to exactly 40KB works best to avoid hitting these boundary mismatches.
