If your files exceed the official portal rules, you can [compress PDF for IBPS PO](/exam-photo-resizer) for free to bypass the 'file size exceeds limit' error instantly.

Who needs this guide

This step-by-step guide is written specifically for banking aspirants across India who are filling out their IBPS PO 2026 application form on the official Institute of Banking Personnel Selection website (ibps.in). Every year, thousands of candidates from tier-1 cities to rural districts struggle with the rigid digital document guidelines enforced by the IBPS portal. When you are rushing to complete your application before the deadline to secure your preferred exam center, encountering an automated "Upload failed" or "File size exceeds limit" error can be incredibly stressful—especially when you have already paid the ₹850 application fee (or ₹175 for reserved categories).

When I tested this size format on the portal with a raw 3MB smartphone scan, the server immediately timed out and rejected the document. Most applicants capture their physical photographs and handwritten signatures using high-resolution mobile cameras, which naturally produce files ranging from 2MB to 6MB. The IBPS automated verification script is hardcoded to reject any file that deviates even by 1 KB from the mandatory constraints. This guide shows you exactly how to resize, format, and compress your images to match the portal's gatekeeper rules perfectly.

Our readers often report that trying to manually edit images using generic computer paint programs ruins the resolution, rendering the signature unreadable. In my experience, compressing files to 40KB for photographs and 15KB for signatures works best because it leaves a safe buffer below the upper limits while fully preserving the quality of your scan. If you want to avoid a rejected application or a stressful last-minute rush, follow the technical preparation steps outlined below.

government / exam portal upload requirements

The IBPS PO 2026 portal enforces distinct file size, dimension, and ink color requirements for each uploaded document. Failing to meet these specifications will result in an immediate upload error, or worse, your application could be rejected during the document verification stage of the selection process. Ensure you use high-quality scans of your documents, but keep their file weights highly optimized.

Fix common portal errors

File too large

If the portal displays a generic "File size exceeds maximum limit" message, your scan is likely hovering just over the 50KB or 20KB thresholds. Even a file that registers as 50.1KB on your operating system will be blocked by the server's strict validation filter. Re-upload the file to our resizer and target a size that is 5KB lower than the maximum allowed limit to ensure a smooth handoff.

Blurry scan rejected

When candidates use aggressive, low-quality compression tools, the resulting image becomes pixelated and illegible. If the system flags your image or if you notice your signature looks fuzzy, do not drop the resolution quality below 80%. Instead, crop the image closer to the borders of the ink to naturally drop the file size, keeping the DPI setting at 150 or 200 to safeguard clarity.

Wrong format

The IBPS portal only accepts files with standard ".jpg" or ".jpeg" extensions. If you scanned your document using a mobile app that automatically saved it as a ".pdf" or ".png", the portal's upload script will freeze or throw an invalid extension error. Use our file conversion utility to seamlessly change your document format to JPEG before starting the upload process.

Upload timeout

If the portal throws a generic gateway timeout error, try compressing the scan further to 140KB for larger files like the handwritten declaration. During peak registration hours, thousands of candidates upload massive files simultaneously, exhausting the portal's active server bandwidth. Reducing your file to a slightly smaller size minimizes the payload size, making it much easier for the IBPS servers to process your upload under heavy load conditions.

What are the exact dimensions required for the IBPS PO photo and signature?

The preferred dimensions for the passport-sized photograph are 200 x 230 pixels, with a file size strictly between 20KB and 50KB. For the signature, the preferred dimensions are 140 x 60 pixels, with a file size limits set between 10KB and 20KB. Ensuring your files match these exact dimensions on the IBPS portal guarantees that they will display correctly on your admit card and final score sheets.

Can I upload my IBPS PO signature in blue ink?

No, the official IBPS PO notification explicitly states that the candidate's signature must be written on white paper using a black ink pen. Signatures written in blue ink, gel ink, or using pencil are highly susceptible to being flagged as invalid or unreadable by the automated verification systems. To prevent any risk of application rejection, always sign clearly using a standard black ballpoint pen.

How do I fix the "Specified file size does not match" error on the IBPS portal?

This error occurs when the file you are trying to upload sits outside the strict kilobyte parameters programmed into the registration form. For example, uploading a signature that is 9.8KB or 20.5KB will trigger this specific block. To resolve this, run your file through our online tool and compress it to a safe middle ground, such as 15KB for signatures or 35KB for photographs.

Is it safe to compress my Aadhaar card or certificates using an online PDF compressor?

Yes, compressing your personal identity documents is completely safe as long as you use a secure processing tool. Our platform processes your uploads locally in your web browser and automatically purges all files from our temporary cache immediately after download. This ensures your sensitive personal information, such as your Aadhaar number or date of birth, remains completely secure and confidential.

What should I do if the IBPS portal times out while uploading my 100KB handwritten declaration?

If the ibps.in server experiences high traffic and times out, try compressing your handwritten declaration down to approximately 65KB to 75KB. While the maximum allowed limit is 100KB, a smaller file size requires less bandwidth to transmit, which significantly increases the likelihood of a successful upload over a congested network connection during peak registration hours.
