Image Resizer - Resize Photos — Mac download

If you have used macOS Preview for a one-off crop, you already know the basics. Image Resizer – Resize Photos scales that idea up to batches, adding controls an experienced user expects.

Resize without quality loss — downscaling does not degrade sharpness; the engine preserves the original pixel data where possible.

Rotation presets — 90° clockwise, 90° counterclockwise, 180°. Quick corrections for orientation mistakes across a whole shoot.

Flip — horizontal and vertical mirroring built in. Handy for product shots that need a facing-direction swap.

Crop — trim to a fixed ratio or freeform before the resize pass runs.

Output naming — rename files during export so your final set arrives with clean, sequential names.

Chosen save location — send resized copies to any folder you pick, not just the source directory.

Crop and rotate in batches, tools Permute skips

Image Resizer – Resize Photos vs. Permute 3
Permute converts video, audio, and images. If you need a single tool for all media, Permute wins. But for batch photo-only work, Image Resizer gives you crop, rotate, and flip controls Permute does not offer. Permute is a converter; Image Resizer is a photo prep station.

Image Resizer – Resize Photos vs. PhotoBulk
PhotoBulk adds watermarking — something Image Resizer skips. Both handle batch resize and format conversion. Image Resizer pulls ahead on rotation: dedicated 90° and 180° presets versus PhotoBulk's more limited orientation options. If watermarking matters, go PhotoBulk. If rotation speed matters, stay with Image Resizer.

Image Resizer – Resize Photos vs. Preview
Preview is free and built in. It can resize and rotate single images. It cannot batch-process, flip, or rename output files. For one image, Preview works. For twenty product shots that need a 50% downscale, JPEG conversion, and sequential naming, an image resizer - resize photos for mac free download like this one saves half an hour.

Workflow: product shots for a web store

A typical task — you have thirty-five product photos from a shoot. They are 4000 px wide TIFFs. Your store template needs 1200 px JPEGs with a clean naming scheme.

1. Open Image Resizer. Drag all thirty-five TIFFs into the window.
2. Set Resize by pixels, width 1200, height locked to ratio.
3. Tick Convert format and select JPEG. Leave quality at 90%.
4. Enable Rename. Set prefix to product_ and starting number to 01.
5. Choose a destination folder — a new folder called web-ready on the desktop.
6. Hit Process. Thirty-five renamed, resized, converted JPEGs land in one place.
7. Spot-check three images: open in Preview, confirm sharpness and framing. If one needs a horizontal flip, drag just that image back, flip, and re-process.

The whole job takes under two minutes. No script, no export preset to build — just a checklist of settings you can save mentally for next time.
