Batch Resize Photos on Mac

Modern cameras and phones produce images that are far larger than most use cases require. A 12-megapixel photo might be 4000x3000 pixels — great for printing, but way too big for a website, email attachment, or social media post.

Resizing images one at a time in Preview or Photoshop is tedious. If you have dozens or hundreds of photos to resize for a web gallery, a blog post, or a client deliverable, you need a tool built for batch processing.

Photo Tamer gives you three ways to resize: set a maximum width, a maximum height, or use fit within to constrain both dimensions at once while preserving the aspect ratio. Your images always look right.

Just drag your photos onto the Photo Tamer icon in your menu bar, choose your target size, and every image is resized in seconds. No complex UI, no project files, no learning curve.

If you manage a blog, an online store, or any website with images, you know that oversized photos slow down page loads and waste bandwidth. Photo Tamer makes it trivial to resize an entire shoot to web-ready dimensions before uploading.

And because Photo Tamer is under 10MB, uses virtually no CPU when idle, and processes everything locally on your Mac, it’s the lightest tool you can add to your workflow.
