Compress an image
An upload form wants a photo under 1 MB and yours is 6. Drop it below and pick Compress to get a much smaller JPG, or Half size to halve its dimensions. It all happens inside this page.

Free, with no sign-up and no upload: the conversion runs inside this browser tab. Lemon for Mac does the same from Finder, for whole batches and for video, audio and PDFs too.
- Converted files show up here, ready to download.
Two ways to do it on a Mac.
One click in Finder.
- 1Hold Option and click the image in Finder.
- 2Flick it onto Compress on the lemon that appears.
- 3A smaller copy lands beside the original, which stays untouched.
Select several files first and they are all converted together. Nothing is uploaded: Lemon works with Wi-Fi off.
Using Preview.
- 1Open the image in Preview.
- 2Choose Tools, then Adjust Size, and lower the width to shrink the dimensions.
- 3Or choose File, then Export, set Format to JPEG and drag Quality down.
Preview shows the resulting size as you drag, but it is one image at a time.
Questions.
It varies by image. A typical phone photo comes out several times smaller with Compress, and smaller again with Half size. The size before and after is shown next to each result.
Every file, one flick.
Lemon converts images, video, audio, PDFs and documents from Finder. $4.99 once, no subscription.
