What is the best free image resizer for Windows 11/10?

If you have hundreds of photos from your iPhone and want to resize them on Windows 10/11, the main challenge is usually balancing file size, image quality, and batch processing. Just cranking down dimensions often results in blurry or pixelated images, and most basic photo resizers struggle with large sets of files.

For me, a tool that really stands out is HitPaw FotorPea. Its AI-based photo enhancement engine does more than just resize: it helps preserve image clarity while reducing file size, which is especially useful if you need each photo under 100 KB for social media, websites, or personal projects. It also supports batch processing, so you can handle hundreds of images in one go without manually resizing each one.

So for your scenario—bulk resizing iPhone photos under 100 KB while keeping them presentable — HitPaw FotorPea is my go-to for the combination of speed, batch processing.
