JPG to JFIF Converter
Need a .jfif file for an app or workflow? Imgovo saves a standard JPEG with a JFIF header and .jfif filename. JFIF and JPG use the same JPEG image codec.
JPG photos are placed in the PDF exactly as they are (no quality loss), so metadata such as the location stays inside the PDF. To remove it first, use Remove EXIF Data.

Frequently asked questions
Is JFIF a different image codec from JPG?
No. JFIF is a common way of packaging JPEG data. The extension changes to .jfif, while the image remains JPEG.
Can I simply rename a JPG?
Many JPG files are already JFIF, so renaming may work. This converter re-saves the pixels and ensures a JFIF header; re-saving a JPG can introduce a small quality loss.
What about transparent images?
JPEG/JFIF does not support transparency. Imgovo places transparent parts on a white background.
Are my images uploaded to a server?
No. Conversion happens entirely in your browser on your own device. Your images are never sent to Imgovo or anyone else.
Can I convert several images at once?
Yes. Select or drop as many images as you like. They are converted one after another, and you can download each file or all of them together as a ZIP.
Can I undo a change?
Yes. Undo and Redo appear above the list once you add files (or press Ctrl+Z / Ctrl+Shift+Z). They bring back a file you removed, undo “Clear all” and return to the previous quality or format — files are converted again automatically when needed.
Is the converter free?
Yes — free, with no signup, no watermark and no daily limit.
