PhotoResize

Fast, Flexible, and Flawless Batch Image Resizing.

4.8

PhotoResize removes the friction from preparing large image collections for web publishing, email sharing, or digital archiving. Built natively for macOS, it processes massive libraries entirely on your device — no subscriptions, no cloud, no compromise on privacy.

Key Features

Lightning-Fast Batch Processing

Drag and drop thousands of images or entire folders and process them all simultaneously — optimised CPU multithreading makes short work of even the largest image libraries.

Flexible Resizing Modes

Resize by exact width, height, percentage, or scale to fit within a bounding box — with options to crop, stretch, or fill rectangles while perfectly preserving original aspect ratios.

Sharpness & Resolution Control

Apply sharpening during downscaling to preserve hard edges and overcome fading blurriness. Retain original resolution or set a new DPI for precise output control.

Smart Sequential Renaming

Rename entire collections using automated patterns — combine prefixes, suffixes, counters, date stamps, and token tags like metadata properties and image dimensions into dynamic filenames.

Bulk Format Conversion

Convert between JPEG, JPEG2000, PNG, TIFF, BMP, GIF, PSD, and more — with precise quality sliders and colour model options including RGB, CMYK, and Grayscale.

RAW & Wide Format Support

Supports RAW image types from virtually all DSLR cameras (.raw, .nef, .cr2) alongside PSD, EXR, TGA, ICNS, SGI, and many more — one tool for your entire image library.

EXIF & Metadata Control

Choose to preserve original EXIF, GPS, IPTC, and TIFF metadata — or strip it entirely to reduce file footprint and protect location privacy on shared images.

Folder Structure Preservation

Maintain your original subfolder hierarchy at the destination — processed files are automatically organised into corresponding subdirectories exactly as they were.

Fully On-Device & Private

All processing runs natively on macOS with no internet connection required. Your photos never leave your machine — fast, secure, and completely offline.

“Does what it says”

This is very simple and it does exactly what it supposed to, its great for getting photos ready to upload for the web. However whilst trying to find out how to get my files from IPHOTO i found that i can batch resize using the export function in IPHOTO but super image resizer has much more flexibility than i photo as you can select and size you want, wheras IPHOTO only has small, medium and large. Anyways this is a great simple program which…

“Works perfectly”

You can drag and drop a whole folder's worth and resize them - super fast too. This is a great tool to resize printable files for web (or iPad) display. An artist's dream to create an easy portfolio. It would be cool if it cropped files too - There are edge effects I'd loe to have trimmed off. But this is a wish, not a criticism.

“Better than Bl*w-*p”

Amazing. Super Image Resizer is better than ASBU, hands down! With none of the messing around. I couldn't believe when I picked a photo at random and resized it to 200% with the settings straight from the factory. Perfect! Then I resized the resulting file 200% again and it was still good! You'd better snatch this up at 99 before the price goes up to $99 or $199. I can't say enough good about it.

“Wow! What did I pay for this app? Ninety-nine cents??”

Wow! I am quite surprised by this app! I just accomplished a lot of tricky standardizing of images for my website -- the website looks so much better now! I loaded all the image files into the Image Resizer, feeling a little skeptical, clicked the "Resize All" button, and I couldn't believe my eyes when all these new files instantly appeared on my desktop. I thought, "Oh these files won't upload or something, right?" They opened up and loade…

“Fantastic! Easiest Photo Resizer I have ever used!”

Very user friendly, simple, easy to customize and love how I can keep original file name and just add a prefix or suffix to it. Or even have an entirely new file name. Great great app. I use it for Websites I am developing that have a lot of photos and do not need them to be the largest possible where a simple 800X600 would work. Easy to resize all of them from the same or separate folders, put them all nicely into a new single folder, uploa…

“It worked!”

I just needed to resize a photo and I got what I needed in this app. Very easy and the price couldn’t be beat. This was something I used to use Photoshop for but I don’t have it now and didn’t want to spend that kind of money. The price for this app was a no brainer. Thanks!

“like a Swiss knife”

in a world that is on a double track to ever bigger photography ( 50 mPix) and diminutive smartphone screens on the receiving end, this hassle-free app is the perfect tool. A few clicks and a resized pic goes where you want it to. I use it daily (MacOs). It would be the ultimate tool if the user could additionally set the sharing app.

“simple fast easy”

I use this to quickly resize photos on my Mac to send via email. Works great right out of the photo app or looking at files on the computer. Remember to go into settings on your Mac to make PhotoResize available on your "open with" options to make it easier to use.

“Perfect app!”

This did exactly what it says on the box - I had a folder of over 500 photos I needed to resize to a max width OR height of 1000 pixels - it was super easy and done in about 1 minute. Thank you! It would be nice to have the option to maintain file folder structure, but in my particular case it wasn't necessary.
