Ultrawide QHD cover resizing
This tool automatically applies a center-weighted crop to fit your files into a 3440×1440 pixel canvas. This dimension targets Ultrawide QHD monitors, providing a sharp 21:9 aspect ratio for wallpapers and cinematic web banners.
When you add an image, the tool proportionally scales it to fill the entire 3440×1440 frame. Any vertical overflow is cropped away, keeping the wide perspective accurate without stretching your source file.
Batch wallpaper resizing
You can resize multiple images to the 3440×1440 layout at the same time. A local worker pool handles the heavy canvas resize image operations directly on your hardware.
Drop a collection of JPEG, PNG, or WebP files into the queue. After processing, you can view the individual 3440×1440 outputs or download the entire batch as a ZIP archive.
Local canvas processing
All resizing and pixel rendering occur exclusively within your browser. Your images are never uploaded or processed on external servers.
Because the tool uses your own device to resize image canvas files, large high-resolution source images will produce the sharpest ultrawide outputs rapidly and privately.
