Why does my PDF upload fail?

PDF uploads often fail because the file is too large, the filename has unsupported characters, the file format is wrong, the PDF has too many unnecessary pages, or the browser or portal has a temporary upload issue.

How do I make a PDF smaller for upload?

Remove blank or duplicate pages, crop large margins or scanner borders, then compress the final PDF. Always check that text, names, dates, signatures, and numbers remain readable.

What filename should I use for PDF uploads?

Use a simple filename such as application-documents.pdf, assignment-final.pdf, or supporting-documents.pdf. Avoid emojis, brackets, very long names, and special characters like #, %, &, +, /, or ?.

What should I check before uploading a PDF?

Check that the file is a PDF, the size is below the upload limit, the filename is simple, pages are readable and correctly rotated, and no blank or unnecessary pages are included.

PDF upload troubleshooting workflow

Check the required format — confirm the portal needs PDF, not JPG, PNG, DOCX, or ZIP.
Check file size — reduce the PDF if it is above the upload limit.
Rename the file — use a simple filename without symbols, emojis, brackets, or very long text.
Remove unnecessary pages — delete blank pages, duplicates, and old versions.
Crop large margins — remove scanner borders and extra background.
Rotate pages — fix sideways scans before submitting.
Compress the final PDF — then check readability before upload.
Try another browser or device if the file is correct but the upload button still fails.

Many upload systems work better with simple filenames. Avoid symbols like #, %, &, +, /, ?, brackets, emojis, and very long names.
