Drop multiple images at once and download everything together as a ZIP.
Use this tool when Windows or your phone saved a photo as .jfif and an app, website or editor will not open it. JFIF is the same data as a JPEG, so this rewrites it as a standard .jpg locally in your browser, with no quality loss at full quality.
Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.
JFIF to JPG is the fix for photos that Windows, Microsoft Paint or your phone saved with a .jfif extension that apps and upload forms refuse to open. A JFIF file is the same image data as a JPEG, so converting it is instant and, at full quality, completely lossless. Everything runs locally, with nothing uploaded.
A .jpg file is accepted by every app, phone, website and upload form, while .jfif is often rejected.
JFIF is already JPEG data, so at quality 100 the image is rewritten with nothing thrown away.
Files convert the moment you drop them, locally in your browser, with no upload and no waiting.
Drop a whole folder of JFIF files and download them all as JPG in one go.
JFIF stands for JPEG File Interchange Format. It is simply the standard container the JPEG format uses, and the .jfif extension shows up because some Windows updates and browsers started saving JPEGs that way. The pixels are identical to a normal JPEG, so this tool changes only the extension and container, not the image. If you need lossless quality or transparency instead, use JPG to PNG, and to make a photo smaller, try Compress JPEG.
These tools solve similar image optimization problems and work the same way: locally in your browser, with no required upload.
JFIF (JPEG File Interchange Format) is the same image data as a JPEG, just saved with a .jfif extension. Windows and some browsers create them, which is why apps sometimes refuse to open them.
No noticeable loss. JFIF is already JPEG data, so at quality 100 this simply rewrites it as a .jpg. Lower the quality only if you also want a smaller file.
Many programs and upload forms only recognise the .jpg or .jpeg extension. Converting to JPG gives you a file that opens everywhere.
Yes. Drop a batch and each one is converted locally in your browser, with individual downloads plus a download-all option.
