Frequently asked questions
Can I open PNG files in ViewerPix?
PNG is lossless and supports transparency. It is useful for graphics, screenshots and images that need crisp edges. 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 PNG 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 PNG 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.
