Yes, for 50 photos a day, with every format, every quality setting and no limit on how many you drop at once. Pro is $34.99 once, not a subscription, with free updates for all of version 1. It removes the daily count and adds the delivery tools: watch folders, crop, rename, several sizes at once, logo and QR watermarks, and fit under a size.
Not at the size people look at them. On the 56 test photographs at quality 60, 49 scored 80 or more out of 100 on SSIMULACRA 2, an independent measure of how close a copy looks to its original, where 80 is very high. Before you save, you can compare the two at actual pixels, side by side or with a wipe.
It depends on the photo and the setting. At quality 60 and full size, the 56 test photographs came out 28% to 77% smaller, a little over half on average. A lower quality or a smaller size saves more.
On 56 full-size photographs from Unsplash, 0.5 to 16.4 MB each and up to 131 megapixels, with Image Shrink 1.0 at quality 60 and the original size kept. All 56 came out smaller, by 28% to 77%. Together they went from 263.6 MB to 118.8 MB. Every original was checked byte for byte afterwards, and none had changed. To judge the look, both files were scaled to 2560 pixels wide and scored with SSIMULACRA 2: 49 of 56 scored 80 or more, the middle one 85.5 and the lowest 69.8. At the same score, Image Shrink's file was smaller than the Mac's own JPEG on 52 of 56.
No. Image Shrink runs in the Mac's sandbox and was never given the internet, so it works the same with the Wi-Fi off; only buying Pro needs the App Store online. macOS lets it open the files and folders you choose and remember a folder for a watch folder, nothing else. With Compress images I copy switched on, it also sees the images you copy. To check: codesign -d --entitlements - "/Applications/Image Shrink.app" in Terminal.
Never. Every save is a new file in the folder you choose, and an original is never written over. If a name is taken, the new file gets a number, like (2), at the end. A watch folder can move an original into a Done folder if you ask it to; it never deletes one.
Yes, free. Drop the HEIC photos, choose JPEG under Format, and save. PNG, WebP, AVIF and JPEG XL work the same way.
Yes. Select photos or a folder in Finder, right-click, and choose Compress with Image Shrink. They open in the app as if you had dropped them. Open With works too.
Not as a plug-in. Point a watch folder at Lightroom's export folder and every export is compressed as it lands, with the recipe you gave that folder. The same works with Capture One or any app that exports files. Watch folders are Pro.
Yes. The Compress images action takes your files and one of the free presets, so a shortcut or an automation can compress for you.
In: JPEG, PNG, HEIC, HEIF, WebP, AVIF, TIFF, GIF, BMP, JPEG XL and camera RAW. Out: JPEG, PNG, WebP, AVIF, HEIC or JPEG XL. Animated images and files with several pages are left as they are.
JPEG through jpegli, not the encoder macOS gives every app. PNG at the highest standard setting, and through zopfli when Effort is set to Thorough. A PNG with 256 colours or fewer becomes a palette, identical pixel for pixel; one with more is left alone. A 16-bit PNG stays 16-bit, and Display P3 photographs keep their profile unless you ask for sRGB.
They keep the layer that makes them glow on a bright screen. Where a choice would lose it, the app says which choice.
