Who needs this guide

Every year, hundreds of thousands of bank aspirants across India register for the Institute of Banking Personnel Selection Probationary Officers (IBPS PO) exam. Whether you are applying from a fast cyber cafe in a metropolitan city or on your personal smartphone from a rural district in Bihar, Madhya Pradesh, or Karnataka, the application process presents a significant technical bottleneck: the document upload stage. The official IBPS registration portal employs an automated validation script that checks the exact file size (in Kilobytes) and pixel dimensions of your uploaded attachments.

In my experience assisting candidates through these registrations, the most common roadblock is the dreaded 'File size exceeds limit' or 'Invalid image dimensions' warning. This error message pops up instantly, blocking you from proceeding to the fee payment page. Candidates often attempt to resize their images using offline paint tools, which inevitably ruins the image resolution, leading to a pixelated document that risks immediate rejection during the document verification stage.

Our readers often report that they spend hours trying to scan, rescan, and crop their files to hit the narrow window of 20KB to 50KB for the passport photo and 10KB to 20KB for the signature. When I tested this size format on the portal, I realized that even a 1KB variance—such as a 50.1KB photograph or a 9.9KB signature—causes the server to automatically reject the upload. This step-by-step guide is designed to help you prepare your files perfectly to ensure a smooth, error-free registration.

government / exam portal upload requirements

The automated system on the IBPS portal accepts specific formats and file sizes for each document. When scanning your documents, you must ensure that you are saving them in either JPG or JPEG formats. The portal will not accept PNG, PDF (for photo/signature), or HEIC files from iPhones.

Below is the official breakdown of the file sizes and dimensions required for the IBPS PO 2026 registration:

Remember, your signature must not be in CAPITAL LETTERS. The portal's automated pattern recognition system is highly sensitive; uploading a signature in block letters will result in your application being flagged or rejected later during the exam intake cycle.

Fix common portal errors

File too large

If your file size is even slightly over the maximum threshold (e.g., a 51KB photo or a 22KB signature), the IBPS server will reject the upload and show an error box. To fix this, import the file into the Siliph resizer and target a size exactly 5KB below the maximum limit (aim for 35KB for photos and 15KB for signatures).

Blurry scan rejected

If your scan is over-compressed, the text of your handwritten declaration or signature will look blurry or blocky. To resolve this, keep DPI at exactly 150 to preserve scan readability. Do not compress your files below the minimum thresholds (avoid dropping below 10KB for signatures and 50KB for declarations).

Wrong format

Many modern smartphones save photos in HEIC or PNG formats. If you try uploading these to the IBPS site, the portal will show an 'invalid format' error. Ensure you use the Siliph tool to convert and save your outputs strictly as JPG or JPEG files before attempting an upload.

Upload timeout

A slow internet connection or high traffic on the IBPS servers often triggers a gateway timeout. In my experience, compressing files to 150KB for PDF documents and keeping photo/signature files at minimum acceptable sizes (like 25KB and 12KB respectively) reduces the payload, allowing successful upload even on weaker 3G or rural broadband connections.

FAQ

What is the exact photo size limit for IBPS PO 2026?

The official photo size limit for the IBPS PO 2026 registration is strictly between 20KB and 50KB. The image dimensions should ideally be 200 x 230 pixels, and the file must be in JPG or JPEG format. If your photo is outside this range, use our free resizer tool to fine-tune it.

Why does the IBPS portal reject my signature even if it is 15KB?

If your signature is within the 10-20KB limit but still gets rejected, check the file name and ink color. The portal will reject signatures containing spaces or special characters in the file name (like `my signature.jpg`). What's more, ensure the signature is written in black ink on white paper and is not in capital letters.

Can I upload a signature in blue ink on the IBPS exam portal?

No, the IBPS PO official notification explicitly states that the signature must be written with a black ink pen on white paper. Uploading a blue ink signature may lead to rejection during the verification stage. Scan your black ink signature and compress it to between 10KB and 20KB using our online tool.

How do I compress my handwritten declaration to under 100KB without losing readability?

The handwritten declaration must be between 50KB and 100KB written in English with black ink. To compress it safely, select a 150 DPI setting on your scanner or scanner app, then use the Siliph tool to set a target size of 80KB. This keeps the handwriting perfectly readable while staying under the limit.

Can I use my mobile phone to resize and upload documents for the IBPS PO application?

Yes, you can easily use your mobile browser to access the Siliph resizer tool. Simply take a photo of your documents, upload them to our mobile-friendly page, compress them to the required KB ranges, download them directly to your phone's downloads folder, and upload them to the official IBPS portal.
