JPG / JPEG extension fixer

Getting “invalid file format” even though your file ends in .jpg? It may really be a PNG or WebP with the wrong name. This checks what's inside and gives you a true JPG.

Why renaming doesn't work

A file's name doesn't change what's inside it. Forms check the content. Screenshots are usually PNG, and images saved from WhatsApp or websites are often WebP, even when they're named .jpg. This tool reads the first bytes of your file. If it's already a real JPEG, you get the same file back with a .jpg name. Otherwise it's converted. .jpg and .jpeg are the same format; only the spelling of the name differs.
