How to Fix “File Type Must Be JPG”

Convert unsupported PNG, HEIC, WebP or AVIF input to JPG without confusing format conversion with compression.

Open the toolOpen JPG-required 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.

Do it now, not one file at a time.Open JPG-required preset →
