Larger images shrink to fit; smaller ones keep their size. SVGs are drawn at exactly this size.
Fills transparent areas, since JPG can’t keep them.
Free, no sign-up. Location and camera details (EXIF) are always removed: each file is redrawn and saved fresh.
JFIF to JPG · Free · No upload
A .jfif file is a JPEG with an unusual name, often given by Windows when you save an image from a browser. Upload forms that check the extension reject it; converting gives you a normal .jpg, for many files at once.
Your files never leave your device.
Drop them in, a few or a folder's worth.
They're saved again at quality 90, which looks the same.
Each .jpg separately or all in a ZIP.
