A file upload can fail even when the document looks correct on your phone or laptop. Indian recruitment, government, college, and exam portals may reject files because of size, format, file name, browser session, metadata, or heavy deadline traffic.
Check the upload rule again
Do not assume the same rule applies to photo, signature, marksheet, and certificate uploads. One field may need JPG, another PDF. One may use a file-size range, while another may reject large dimensions.
Rename the file simply
Some portals do not handle special characters well. Rename the file with plain English letters, numbers, and hyphens.
Better: photo-july2026.jpg signature-final.jpg marksheet-sem6.pdf Avoid: Nikhil final (latest) scan!!!.jpg
Check file size and dimensions
If an image is too large, resize and compress it gradually. If a PDF is too large, try scanning at a reasonable quality instead of using an oversized camera image inside the PDF.
Try a fresh browser session
- Save your form progress if the portal allows it.
- Open a fresh browser window.
- Disable unnecessary extensions for the session.
- Clear only the portal tab cache if instructed, not all important browsing data blindly.
- Try a stable internet connection.
Re-save the file if metadata is broken
Sometimes an image or PDF opens locally but fails online because the file is damaged or has strange metadata. Open it in a trusted viewer and export or save a clean copy. Then upload the new copy.
Deadline traffic strategy
During final hours, state portals, university admission sites, and exam forms can slow down. If payment or final submission is involved, do not keep testing randomly. Take screenshots of errors where appropriate, note the time, and use the official helpdesk route if available.

FAQ
Why does the upload fail after reaching 100 percent?
The upload may complete but server validation may fail because the portal rejects the format, size, dimensions, session, or file name.
Should I keep clicking submit again and again?
No. First identify the error pattern. Repeated clicks can create duplicate attempts or payment confusion on some portals.
