My final post on this topic. I would like to thank all participants of this discussion for providing a wealth of choices in image optimizers.
I gave up my quest for best image optimizer that runs natively on Arm processors. Instead, I installed Rosetta 2 (something I wanted to avoid previously).
As soon as I did that, I updated ImageOptim to the latest version, which now can run on M-based Macs, as far as I can tell. Oh, well… At least now I can also use few other less important, old 64-bit apps.
Apologies to Rob @fapkogi for hijacking, bt this seems the most logical place to add info.
As some will have guessed, I have become a hugh fan of Retrobatch - it is the most capable image processor I have come across in a long time and my site images are all gradually being transformed to the size efficient .webp.
Today, Retrobatch 2.1 is out of beta and available and there is a discount available to anyone still using version 1.
All information here:
Retrobatch 2.1
The Mac’s flagship batch image processor has a feature update as well!
# New stuff
A new Look up Table (LUT) node! The LUT node can be used to quickly and easily alter the color and tone of your images. LUTs can be used to create a wide range of effects, from subtle color adjustments to dramatic stylistic changes — it’s like a pre-programmed filter, but with more flexibility and control. Use one of Retrobatch’s LUT presets, or download additional LUTs that emulate film stocks, create specific moods (like warm, cool, or vintage), or simply enhance the natural colors in your image.
You can also adjust the opacity and blending mode of the LUT. Use a grayscale LUT and then dial back the opacity to create some dramatic effects in your images.
(Retrobatch Pro only)
New “Tile Chop” node which will take an image and split it up into multiple images based on a width and height set in its properties.
New “Camera Capture” node which uses your Mac’s built in camera to take a photo (Retrobatch Pro only).
Photos Export now has an option to export the Current, Unadjusted, or Original versions of your Photos Library images.
New “Auto Process” option in the RAW Import node. This lets you skip the fiddly options and just lets Retrobatch make the best guess at how the image should be processed.
Two new nodes for renaming files. “File Rename” which will take one search string and replace it with another, and “Web Safe Rename” which will take a sequence of characters and then replace those with a given string. This is handy for tasks where you need to take out special characters or spaces from your images to make them easier for handling on the web.* There’s a new Advanced tab in Preferences, with some new options:
A new “Default Write Folder” that will be used anytime you add a Write node.
A “Clear JavaScript console when a workflow runs” option, which is useful for plugin authors. * A “Allow unknown file types” option, which can be used to load ancient file types that MacOS no longer recognizes (Pro only). Find out more about this preference if you find it intriguing.
To update to Retrobatch 2.1 use the Retrobatch ▸ Check for Updates… menu item, or update it via the Mac App Store if you purchased it there. If you were using Retrobatch 1.x, you can get the latest release via our website.
