The .jfif files that Windows Paint or email attachments sometimes save are actually JPEG data, yet their extension keeps some programs from opening them. This tool re-saves JFIF as standard JPG (or PNG when you need transparency) right in your browser, so it opens anywhere.
How to use
- Drag and drop the .jfif file, or click to select it.
- Choose the JPG or PNG tab; for JPG, adjust the quality and background color.
- Check the preview, then save the converted image with the download button.
FAQ
- What's the difference between JFIF and JPG?
- The underlying data is nearly identical. JFIF is one of the container specs for JPEG images, and compatibility problems arise simply because it's saved with a .jfif extension. Re-saving turns it into a standard .jpg that most programs open right away.
- Does converting reduce the image quality?
- JPG uses lossy compression, so re-saving can introduce slight loss depending on the quality slider. To preserve the original as much as possible, set quality to 90% or higher, or convert to lossless PNG.
- Is my file sent to a server?
- No. All conversion happens only in your browser, and the image is never uploaded to or stored on a server.
