Same size in pixels, a lighter file
One compressed copy per file, at the same dimensions. A PNG is lightened only where the image is textured, by differences too small to see — gradients and transparency come out exact. A JPEG is re-encoded only when the original leaves room for it, and a copy is kept only if it is at least five percent lighter.
PNG and JPEG are not treated the same
A PNG with 256 colors or fewer — a logo, an icon, a diagram — comes out with nothing lost at all. Above that, the differences are too small to see, and gradients and transparent pixels are left as they were. A JPEG keeps its orientation, its color profile, its date and its camera details.
A safety net when it does not work
When a copy would not be at least five percent lighter, Ricly writes nothing at all and says so — you are never left with a copy that gained nothing, and your original is never touched.
Nothing to download, nothing sent
Everything ships inside the app, so there is nothing extra to install, and no picture leaves your disk to be optimized somewhere else.
The compressed copy lands beside it
Same folder, name with a suffix. Your original is not modified, moved or deleted — which matters, because compression is a trade and you may want to look at both.
Ricly vs. Preview and online compressors

WHAT IT REPLACES
A whole selectionone lighter copy each,
originals untouched
A folder of screenshots is one right-click. The menu reads Compress Image (20 files) before you click, and each file gets its own lighter copy beside it.
macOS has its own way, in Preview. Tools › Adjust Size, Resample image, then a smaller resolution, and Apple shows how to do several images at once from the sidebar. That route makes the picture smaller in pixels. Ricly keeps the dimensions and makes the file lighter, and if a copy is not at least five percent lighter, you keep the original and nothing is written.
Lighter, not worse.
A screenshot for a ticket, a photo for a listing, a mock-up for a client. Smaller to send, the same dimensions, and the original still where it was.
You came for one tool. 16 more come with it.
Compress Image is not an app you install. It is one item in a menu that also carries 16 others — same download, same account, nothing extra to set up.
13 are free, 4 are Pro. They install themselves as they ship, so the menu grows without you doing anything. Quick Resize brings the pixel count down when the weight is not the only problem, and Convert to WebP is the next step for anything headed to a website.

Compressing images on a Mac: common questions
How do I reduce an image’s file size on a Mac without installing anything?
In Preview, choose Tools › Adjust Size, select Resample image and enter a smaller resolution; to do several, open them in one window and select them in the sidebar first. In the Finder, Quick Actions › Convert Image (under More on macOS 27) can also save a smaller size.
Can I compress an image in the Terminal?
macOS includes sips, which can re-save a JPEG at a lower quality: run sips -s formatOptions 70 photo.jpg --out photo-small.jpg in the Terminal. Ricly does the job from the right-click menu, for PNG and JPEG alike.
How much smaller does it get?
It depends on the picture. If the copy is not at least five percent lighter, nothing is written, and the tool tells you so.
What if a site wants it under 2 MB?
Compress Image makes the file lighter at the same dimensions, with no size target. When a form or a marketplace refuses anything over a given size, use Quick Resize, Under…, in the same menu: it keeps the size in pixels if the file already fits, and otherwise picks the largest size that does.
Can it make the file bigger?
No. If the copy is not at least five percent lighter than the original, Ricly writes nothing and tells you the file is already optimized. You never end up with a heavier file wearing the compressed name, and the original is left exactly as it was.
Which files can I use?
JPG, JPEG and PNG. HEIC photos go through Convert to JPG first, in the same menu; anything headed to a website is often better served by Convert to WebP.
Is the picture uploaded anywhere?
No. It runs on your Mac, and the picture never leaves your disk.
Where does the new file go?
Beside the original, with -compressed added to the name. Your original is not modified, moved or deleted, so you can compare the two and throw away the one you do not want.
Can I compress a whole folder at once?
Select the files and right-click: the menu reads Compress Image (20 files), and each gets its own lighter copy. If a name is already taken you get a numbered file rather than an overwritten one.
Right Click. Done.
