There can be several reasons why you may be unable to upload scanned documents or photographs in the application form for the IBPS PO Exam. However, there are a few steps you can take to resolve this issue and successfully submit your application.

1. Check the File Format:
Ensure that the scanned documents or photographs are saved in the correct file format as specified by the IBPS. Typically, PDF or JPEG formats are accepted. Convert the files to the required format if necessary.

2. Resize the Files:
The IBPS usually imposes a size limit for each uploaded file. If your files are too large, try resizing them using appropriate software or online tools. Compressing the files can help reduce their size without compromising the quality too much.

3. Check the Internet Connection:
A stable and reliable internet connection is crucial for uploading files. Make sure you have a strong internet connection to prevent any disruptions during the upload process. If you are experiencing slow internet speed, consider switching to a different network or contacting your service provider for assistance.

4. Clear Browser Cache:
Sometimes, browser cache can cause issues with uploading files. Clear your browser's cache and cookies to eliminate any potential conflicts. Restarting the browser after clearing the cache can also help resolve the problem.

5. Try a Different Browser:
If you are still unable to upload the files, try using a different browser. Sometimes, certain browsers may have compatibility issues with the IBPS website. Switching to a different browser like Google Chrome, Mozilla Firefox, or Microsoft Edge might solve the problem.

6. Contact IBPS Helpdesk:
If all else fails, it is advisable to contact the IBPS helpdesk for further assistance. They can provide guidance and troubleshoot any technical issues you may be facing. The contact details for the IBPS helpdesk can be found on their official website.

Conclusion:
In conclusion, if you are unable to upload scanned documents or photographs in the application form for the IBPS PO Exam, follow the steps mentioned above. Checking the file format, resizing the files, ensuring a stable internet connection, clearing browser cache, trying a different browser, and contacting the IBPS helpdesk are all potential solutions to overcome this issue. Remember to double-check all the requirements and guidelines provided by the IBPS to ensure a smooth application process.
