How to Fix “File Size Must Be 20 KB to 50 KB”
Range-based upload rules have both a minimum and a maximum. Compressing below the minimum can still fail validation.
Open the toolOpen 20–50 KB range preset →Read the requirement literally
Treat each stated field value as a separate constraint: shape, pixels, format, background and file size can fail independently.
Change only what failed
Do not reduce JPEG quality to solve a pixel-dimension error, or change DPI metadata to solve a real pixel requirement.
Verify before submission
Use the linked preset as a starting point, preview the result, and confirm the current receiving form requirement before final submission.
