About JFIF Viewer Online
Use the viewer to open the image, inspect its dimensions and format, zoom, fit, rotate, change the preview background, and switch between multiple files.
About JFIF
JFIF stores JPEG-compressed image data and is closely related to JPG, but the .jfif extension is rejected by some upload forms and older software.
Frequently asked questions
Does opening an image change the original file?
No. Viewing, zooming, fitting, rotating the preview, and changing the preview background do not modify the source file.
Can I open more than one image?
Yes. Add multiple supported images and switch between them using the thumbnail list.
Are my images uploaded to a server?
No. Supported image processing runs locally in your browser. Third-party decoder code may be loaded only when a format needs it, but your image itself stays on your device.
Private browser processing
ViewerPix processes supported images on your device. Your image files are not uploaded to a ViewerPix application server for this task.
