Under the upload limit, on the first try
Portals ask for 2 MB and give you no way to get there. Drop the image on the notch, pick the size you need, and the compressed copy comes back on the shelf — the encoder does the quality search, not you.
Pick the size, not the quality
Targets are 200 KB, 500 KB, 1 MB, 2 MB and 5 MB. The encoder searches quality settings until the file lands under what you asked for, so you never guess at a percentage and re-export three times.
Resize by the long edge too
A separate menu resizes by maximum dimension, and only offers presets actually smaller than the image — a 900px photo is never asked whether it wants to become 1200px.
Whole selections at once
Select two or more images on the drop shelf and the batch button compresses or converts all of them in one pass, results back on the shelf.
On-device, and out of the way
Nothing is uploaded to a compression service — it is Image I/O on your own Mac. The result sits on the shelf until you drag it out, and freeing up disk space is a side effect you can watch on the system card.

Compressing images on Mac — FAQ
How do I compress an image on a Mac without Preview?
Drag it onto the notch, right-click the tile on the shelf and choose a size under Compress to. The compressed copy lands beside the original, so the source file is never overwritten.
What sizes can I compress to?
200 KB, 500 KB, 1 MB, 2 MB and 5 MB. Each one is a real ceiling — the encoder steps quality down until the output is under the target rather than applying a fixed preset and hoping.
Does it compress several images at once?
Yes. Select multiple images on the shelf and the batch action applies one target to the whole selection.
Will it overwrite my original?
No. Every conversion, resize and compression writes a new file and leaves the source untouched.
Does it work offline?
Yes, entirely. The encode runs through the macOS imaging frameworks on your machine, so it works on a plane and nothing is sent anywhere.
Can it resize as well as compress?
Yes — resize by maximum long edge, with presets filtered to those smaller than the image you picked.
