PhotoResize Pro eliminates the biggest workflow bottleneck for photographers, web developers, and digital asset managers — preparing large image libraries for distribution. Built natively for macOS and Windows, it processes entire photo collections at blazing speed with no cloud upload, and no compromise on quality.

Key Features

High-Performance Batch Processing

Drag and drop thousands of high-resolution images or entire folders and process them all simultaneously — optimised multi-core threading makes even the largest libraries fast work.

Advanced Resizing & Canvas Modes

Seven versatile scaling methods including fit, crop, stretch, pad, and fill — with dimension inputs in Pixel, Percent, Inch, CM, MM, and Points. Prevent upscaling, set new DPI, or apply sharpening on downscale.

Industrial Format Conversion

Convert HEIC, RAW, WebP, JPEG, PNG, TIFF, JP2, PSD, GIF, PDF, EXR, and BMP — including animated WebP to GIF conversion and multi-frame image support. Full colour profile management included.

Lossless JPEG & PNG Optimisation

Reduce file sizes without visible quality loss using built-in lossless optimisation for JPEG and PNG — perfect for web publishing, email delivery, and digital archiving.

EXIF & IPTC Token Renaming

Build dynamic filenames using token tags — embed camera model, lens, focal length, date taken, GPS data, image dimensions, sequence numbers, and more, directly into output filenames.

Quick Look Preview

Preview the actual output of your selected resize, conversion, and optimisation settings before committing to export — see exactly what you'll get before a single file is written.

Batch Rotate & Flip

Rotate and flip entire image collections in a single pass — combinable with any other processing option for fully automated orientation correction workflows.

Global Workflow Presets

Save any combination of resizing, conversion, optimisation, and renaming options as a reusable global preset — with a built-in backup system to restore presets after any system reset.

Metadata & Folder Structure Preservation

Preserve original EXIF, IPTC, GPS, and TIFF metadata — or strip it for privacy. Maintain exact source subfolder hierarchy at the destination to keep libraries perfectly organised.

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.

“Great app and Great customer support!”

I just prchased this app and it works perfectly for my photography business. It is a great way to resize image quickly and save them even easier. I emailed them about converting RAW images to JEPEG and they replied within 2hrs. Instead of uploading the RAW images all you need to do is drag and drop them from finder and you're all set. They are working on an update so you can upload RAW images the same as JPEG. Very impressed.

“Love this app! Works great.”

I use Photo Resizer to reduce the file size of jpegs for Keynote Presentations. For example, a 120 MB file will easily be reduced to 15 MB with no reduction of quality (Lossless). I can then use 100 images in a Google Slides show which I ordinarily couldn't do. This app is a life saver.

“Does the job”

I had many hundreds of photos that would consume far too much space in my photo libraries. This utility provides a simple way to apply selected parameters of size reduction to all the photos at once store separately, or over-write the old preserves creation/modification dates if desired. For simple non-studio quality (view on-screen without a plan to print large formats), this tool is superb; photos typically reduce from 6MB to 375KB with…

“Fantastic”

All features that I want can be done in just one click. Option to replace existing files (at different subfolders at the same time can be done) or to save in a new folder. Option to convert in jpg (or other format) or to remain the same format, (and many more options to select). To resize and convert, all is done in just one click after setting the options. Fantastic app and thank you for offerring at affordable price. Thank you. Thank you.

“It Resizes Pictures Easily”

I rarely write app reviews. I just don't have the time. I'm making an exception here. Two or three times a week I have to resize batches of 30-40 pictures. It's a pain to do this one-by-one and Photoshop's "Batch Resize" is clunky at best. This handy little app is fantastic! I just drag my picture in, set the size and destination folder, and I'm ready to go! I have it convert from RAW to JPG and have some pretty big files. It works just fine…

“Great and convenient program”

Love this program. It is a lifesaver. I have to upload a lot of pictures for reports at work. The fact that it resize and converts at the same time also comes in really handy when I get picks that have to .jpg and they are taken in .heic. 10/10. Would recommend.

“Saves me so much time.”

Does exactly what I need. Every week I have to resize and optimize 20 to 150 images for the web after I'm done with the High resolution files. Life saver. I've gone through several other programs and this one just works.

“A pleasure to use”

At first try I’m really pleased with this app, especially the automatic sharpening feature. I haven’t had a chance to work out what kind of sharpening it uses, or how much (and it would be nice if this were adjustable). But when downsizing for the web it’s essential to sharpen, and the results from PhotoResize Pro are loads better than a straight export from, say, Photos.app. The interface looks good and is intuitive to use. I’ve found other…

“So easy”

This is the best resize app I have used on the mac. Really simple but also quite customisable. I’ve saved quite a few custom presets which just make this so quick and easy. I like the options for renaming - allowing for a prefix and suffix. Also an easy to follow manual which helped me work out the resize - ‘type' options. Totally worth the price considering how many batch resizes I do.

“Works as advertised!”

This app is great. It will: - Resize a bunch of photos, to fit a rectangle and keep its proportions, while changing the files name in order of how they are sorted. - Plus lossless compression. - Plus it lets me save the presets I commonly use. This app is a real time saver, and worth the money.
