Why convert JFIF to PDF?

JFIF to PDF: questions & answers
Is converting JFIF to PDF free?
Yes, completely free with no sign-up, no watermark and no daily limit.
Will I lose quality converting JFIF to PDF?
No. PDF is lossless, so the converted image keeps every pixel exactly as it was decoded from the JFIF file.
Can I convert multiple JFIF files at once?
Yes. Drop as many files as you like; they are converted in parallel and can be downloaded individually or as a single ZIP.
Are my JFIF files uploaded?
No. The conversion runs locally in your browser, so your images never leave your device.
Does it work on iPhone and Android?
Yes. The converter works in current versions of Safari, Chrome, Firefox and Edge on phones, tablets and computers. Very large images may exceed the memory available to mobile browsers.
Why do my images save as .jfif?
On some Windows PCs the registry associates the image/jpeg content type with the .jfif extension, so the browser uses it when saving JPEG images. The image itself is a normal JPEG.
