Without compression, I would use x13 as a general rule to figure out how large the resulting image would be.
The basic rule I use for size comparison for JPG to PNG, at factor 9 (highest) compression is x10. I use the *XnView* image browser and shell extension to view, edit, modify and compress PNG's. PNG’s have a preset 1 < 9 system I'm not entirely sure what the percentage/factor is but I do know the end result image size in general so it gives me a ball park figure to work with. Unlike JPG’s which can be compressed by percentage factors. The higher the compression, the long it takes to save, the lower the compression, the faster it will save. Most who know about it don’t know it has a limited compression ability that doesn’t save mega space, but it is directly correlated to space versus time constraints. Have you encountered the issue before? If so, did you manage to resolve it?Īlso I’d like to add, though I solely work with and save all images in PNG format. It may take quite some testing and trying out before you find a solution that works for the images that you want to set as your wallpaper on your system. Some images are not affected by the compression regardless of their original format, while others seem to be compressed no matter what you try. You can use programs such as Adobe Photoshop, Irfanview or XnView for that. What you can try as well is to set the DPI setting to 72.009 dpi and 8bit. You best use an image that has the exact same resolution as the screen resolution of the connected monitor. Right-click on the desktop afterwards and select refresh from the context menu.Make sure you remove the file extension of the picture.Rename the original image that you want to use as your background image to TranscodedWallpaper.Rename TranscodedWallpaper to TranscodedWallpaper_old.It is stored as TranscodedWallpaper in the folder.

Windows saves the compressed wallpaper image that it creates in the C:\Users\%USERNAME%\AppData\Roaming\Microsoft\Windows\Themes folder on the system. In the image editor use the Save As option to save You can use Paint or any other image editor to convert the jpg image to png or bmp. Some users reported that you need to load it in Firefox or another browser (the local converted image), to set it as the background image without compression. You may need to experiment with various ways to set it as your system's wallpaper though. If your source image is a jpg, try converting it to png or bmp format instead before you set it as your background wallpaper.
