Why the upload fails
GATE application photo and signature forms can reject files when size is too high, dimensions are wrong, the scan is too heavy, or the format does not match the current portal rule.
Fix size carefully
Prepare the photo, signature, scan, or PDF against the live rule while keeping key details readable.
Avoid the server loop
Auto Compress is built around a browser workflow and does not store your file on Auto Compress servers 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 helps avoid repeated server-side resize detours.
Check the prompt
Use the current KB, pixel dimension, file type, and upload rule shown by the portal.
Prepare in Chrome
Reduce file size carefully so face, signature, ID text, numbers, and stamps remain readable.
Upload normally
Select the prepared file in the original application flow.
