Batch image renamer/resizer.
There’s a kind of tool that doesn’t try to dazzle you with an overdesigned interface or AI-powered buzzwords. It just works. Image Tuner is one of those tools — a no-frills utility that quietly handles the boring, repetitive image tasks you don’t want to do manually.
Whether you need to resize a single vacation album, convert RAWs to compressed JPEGs, scrub metadata, or throw watermarks on a hundred product shots, Image Tuner is built to get in, get out, and stay out of your way.
Installation
Installation is painless: blink and it’s done. The app opens to a straightforward, if old-school, interface. It's not flashy, but it’s clean and functional. Drag-and-drop works. So does loading folders directly. The learning curve? Basically flat. You’ll be batch processing files within minutes of opening the program.
Batch operations
And that’s where Image Tuner shines. Batch is the entire point. Resize by percentage or custom dimensions. Choose from preset resolutions like 640x480 or 720x576, or define your own. Convert between formats — JPEG, PNG, BMP, GIF, TIFF — and adjust compression settings if you care about file size or quality. The filter options are more sophisticated than you'd expect: Lanczos3, BSpline, linear, and more.
Need to rename everything using a consistent pattern? You can do that too. Want to remove EXIF data before uploading online? Covered. Add watermarks, flip images, rotate them, auto-sharpen, or tweak hue, brightness, and contrast. It’s not a full image editor — but it doesn’t need to be. It’s a batch editor that doesn’t pretend to be anything else.
There’s even a preview window if you want to double-check what you’re about to process. And if you’re halfway through a project, Image Tuner lets you save your progress and come back to it later.
High performance
In testing, performance was rock-solid. No crashes, no memory leaks, no annoying pop-ups. The app runs light, even when crunching through thousands of files.
Bottom line?
Image Tuner isn’t the prettiest tool in your digital toolbox, but it might be one of the most efficient. If you’ve ever wasted time resizing images one at a time, this little app will feel like a revelation. It’s fast. It’s simple. It’s free. And when you’re staring at a folder of 300 photos that all need the same treatment, that’s all that really matters.
