Increase an image to 100 KB
A scanned document looks clear at 40 KB, then the upload box insists on at least 100 KB. Crisp scans of plain text compress hard, so they often miss a six-figure floor by a wide margin.

Why clean scans fall under 100 KB
A black-and-white scan of a typed page is mostly flat white with thin strokes, which is very cheap to store. A single sheet can compress to 30 or 40 KB while staying sharp. That is far below a 100 KB minimum on a document field.
Padding fills the gap by adding filler bytes after the scan data, with no change to a single pixel. The text reads the same, prints the same, and the file now satisfies the form's lower bound.
Document fields that set a 100 KB floor
Loan, visa, and admission portals often require uploaded certificates or ID scans to be 100 KB or more. The rule helps reject near-empty or broken files. A genuine, well-scanned document can still come in under the line.
Pad it up to 100 KB and submit. When a field instead complains that a scan is too heavy, compress to a size brings an oversized file back under its ceiling.
