Sources disagree on this
accepted formats beyond PDF and JPEG
Some forms also accept TIF or TIFF files, and PNG appears in certain photo-specific flows; neither is on the general evidence list.
How we handle it: Prepare PDF for documents and JPG for photographs. Upload TIFF scans directly when a specific form invites them.
