IBPS Signature Upload Error: Invalid Dimension or Size
Fix IBPS-style signature upload errors caused by invalid dimensions, wrong crop, file size, or unsupported image format.
Last verified: July 22, 2026. IBPS and exam upload rules can change by recruitment cycle, form step, file type, and category. Always follow the live KB, dimension, format, and size prompt shown by the destination website.

Why this error appears
IBPS signature upload forms can fail when the file is above the KB target, cropped incorrectly, saved in the wrong format, or prepared through a one-off tool that does not match the current portal prompt.
Fix size and dimensions
Prepare the photo, signature, thumb impression, or PDF against the live rule instead of guessing from old examples.
Keep private files local
Auto Compress is built around a browser workflow, so recurring upload fixes do not require Auto Compress server storage for compression.
Manual fix, then permanent fix
The manual path is to crop, resize, compress, download, return to the form, and retry until the upload accepts the file.
Auto Compress keeps that recurring fix closer to the upload moment. It prepares a smaller file before the destination website receives it, and it does not store your file on Auto Compress servers for compression.
Check the prompt
Use the current KB, pixel dimension, file type, and upload rule shown by the exam portal.
Prepare in Chrome
Reduce file size carefully so face, signature, thumb lines, text, and stamps remain readable.
Upload normally
Select the prepared file in the original application flow and avoid the repeated server-tool detour.
