What is Image Tuner?
Image Tuner applies repeatable changes to groups of images on Windows. It combines batch resizing, file renaming, format conversion and watermarking, making it useful when a collection of photos needs consistent dimensions or naming. Folder and subfolder searches help gather files, while image-list and task-list import and export support recurring jobs.
The publisher also lists cropping, rotation, sharpening, color adjustments and rounded corners, plus PDF creation from original or processed images. Supported formats include JPEG, BMP, PNG, GIF, TIFF and PCX, alongside listed camera RAW formats such as CR2 and NEF. The publisher screenshot shows a file list next to a checked task queue, with a Resize dialog offering percentage sizing and an aspect-ratio option.
Image Tuner 10.3 is offered as a free seven-day trial, not unrestricted freeware. Continued use requires a purchased license. The linked EXE is the publisher's 64-bit Windows installer; a separate standard download is available in its catalog. These details come from publisher documentation and screenshot inspection, not an installation or hands-on processing test.
