Every year, millions of candidates from both urban centers and rural areas attempt to upload their digital passport photographs, signatures, left-thumb impressions, and handwritten declarations.

Our readers often report that cyber cafes charge anywhere between ₹50 and ₹150 just to crop and compress these files. You do not need to pay anyone or risk your personal data on sketchy, ad-riddled websites. This guide shows you exactly how to do it yourself safely, directly from your mobile phone or computer.

Whether you are an aspiring Probationary Officer trying to submit your form before the eleventh hour or someone helping a family member apply, this guide removes all technical guesswork.

government / exam portal upload requirements

The Institute of Banking Personnel Selection (IBPS) maintains highly strict upload validation rules to ensure that hall tickets and verification sheets print clearly. If your upload does not match these digital parameters, the database will refuse to process your application.

Here is a breakdown of the typical requirements for the IBPS PO 2026 registration process:

Step-by-step: compress PDF for IBPS PO

When I tested this size format on the portal, I realized that many standard mobile scanners produce files that are far too heavy. Follow these precise steps to format and compress your documents using our web application.

Fix common portal errors

Even with the right tool, government portal upload systems can be quite finicky. Here are the direct solutions to the most common errors candidates run into.

File too large

If the portal rejects your file with a "file exceeds size limit" message, it means your image is slightly over the limit—even 50.1 KB will trigger this block. Re-upload the file to Siliph, adjust your target quality slider slightly lower (aim for 35 KB for photos and 15 KB for signatures), and run the compression again. This creates a safe buffer below the strict upper limits.

Blurry scan rejected

When files are compressed too aggressively, they lose vital image data, making signatures unreadable. If your document is rejected for being blurry, make sure you are starting with a crisp, well-lit source image. Keep DPI at exactly 150 to preserve scan readability instead of dropping it further to save space.

Wrong format

The IBPS PO registration portal only accepts images in `.jpg` or `.jpeg` format, and certificates in `.pdf` format. If your smartphone saves photos as `.png` or Apple's proprietary `.heic` format, the portal will immediately fail. Run your file through our format conversion setting to save it as a clean, compliant JPEG before trying to upload.

Upload timeout

If the portal throws a generic gateway timeout error, try compressing the scan further to 140KB if it is a certificate PDF. Large PDF files take too long to transfer over congested ISP networks during high-traffic application windows, triggering the IBPS server firewall to drop your connection. Smaller, highly optimized files upload in milliseconds, avoiding timeouts.

What is the exact IBPS PO photo size limit compress standard?

The official IBPS PO photo size limit compress standard requires candidates to upload a recent color passport photograph of 20 KB to 50 KB in JPG or JPEG format. The physical size must be 4.5 cm x 3.5 cm, which translates to pixel dimensions of 200 x 230 pixels. In my experience, setting your target compression size to 35 KB gives you the best balance of visual clarity and guaranteed upload acceptance.

Why does the IBPS portal reject my signature upload?

Your signature will be rejected if the file size falls outside the mandatory 10 KB to 20 KB range, if it is written in capital letters, or if it is signed in blue or red ink. The IBPS instructions clearly specify that signatures must be signed on white paper using a black ink pen in running handwriting. Ensure you compress the file to around 15 KB to avoid automated rejection.

How do I convert a PDF document to the correct JPEG format for IBPS?

If you have scanned your handwritten declaration or left thumb impression as a PDF, you must convert it to JPEG to upload it. Use our online formatting tool to convert the document from PDF to JPEG, and then use the compression slider to bring the handwritten declaration under 100 KB or the thumb impression under 50 KB.

Can I upload a black and white photograph for IBPS PO 2026?

No, the official guidelines strictly mandate a recent color photograph taken against a light-colored, preferably white, background. Uploading a black and white image or using mobile filter apps can lead to your application being flagged or rejected altogether. To manage file sizes for high-quality color images, use our dedicated resizer to reduce physical overhead without sacrificing color accuracy.

What should I do if the IBPS portal throws a generic gateway timeout error?

If you see a gateway timeout error, the portal servers are likely experiencing heavy traffic, or your file size is too large for your internet speed. If uploading a category certificate, try compressing the file down to 140KB to speed up data packet transmission. Also, clear your browser cache, use an incognito window, and avoid trying to upload during peak evening hours when server load is highest.
