JFIF (JPEG File Interchange Format) is a standard that defines how JPEG-compressed image data is stored in a file. While JPG is the more common file extension, JFIF is the formal standard that ensures JPEG files are compatible across different systems and software.
JFIF (JPEG File Interchange Format) is a standard file format for JPEG compressed images. JPG is the common file extension for JPEG files. Both use the same JPEG compression algorithm.

Yes, it is 100% safe. Unlike other online converters, our tool works entirely offline inside your browser using client-side JavaScript. Your images are never uploaded to a server, ensuring total data privacy.
We support image files up to 10MB per image for batch processing. If your JPEG is larger than 10MB, we recommend resizing its dimensions before conversion.
Our tool supports free batch conversion for up to 10 images simultaneously. You can drag and drop a group of files or select them via the file picker, then download them all as a single ZIP file.
Since both formats use the same JPEG compression, the quality change depends on the quality setting you select. At 100% quality, there is minimal to no perceptible quality change. At lower quality settings, you'll see some quality reduction but smaller file sizes.
JFIF files are supported by most modern web browsers and image editing software since they are essentially JPEG files. However, some older software or specific platforms may prefer the .jpg extension. JFIF is commonly used in certain digital camera workflows and printing applications.
