Frequently asked questions

Can I open JFIF files in ViewerPix?

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. ViewerPix opens supported files locally in your browser. Compatibility can still vary with the exact encoding, file size, and browser.

What can I do with a JFIF file in Image Viewer?

Open the image, check its format and dimensions, zoom, fit it to the screen, rotate the preview, change the background, and switch between multiple files. Image Viewer is for inspection, not editing or exporting a new image.

Does viewing a JFIF file change the original?

No. Viewing, zooming, fitting, preview rotation, and background changes do not modify, compress, or replace the original file.

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.
