All tools/Compress Image

The same picture, a lot lighter.

A screenshot too heavy for a ticket, photos that make a page crawl, a PNG of four megabytes that should weigh four hundred kilobytes. Right-click and a compressed copy lands beside it, made on your Mac.

WHY YOU WOULD INSTALL IT

You have done this a hundred times.

  1. Open a browser
  2. Find a compressor
  3. Upload the picture
  4. Pick a quality
  5. Download it
  6. Move it back
  7. Close the tab

Ricly puts that one in the menu that is already under your cursor. Right-click the picture, pick Compress Image, the lighter copy lands beside it. Up to seventy per cent lighter, with nothing you can see, and nothing uploaded to get there.

SUBTITLED

What you get, exactly.

One compressed copy per file, and the same picture inside it. A PNG is rewritten so that no pixel moves by more than two levels out of 255, and only where the image is textured — gradients and transparency come out exact. A JPEG is re-encoded only when the original leaves room for it, and the result is compared with the original before it is kept.

PNG and JPEG are not treated the same

A PNG with 256 colours or fewer — a logo, an icon, a diagram — comes out with nothing lost at all. Above that, the loss stays under two levels out of 255 and never touches a gradient or a transparent pixel. A JPEG keeps its orientation, its colour profile, its date and its camera details.

A safety net when it does not work

A file that is already compressed cannot get lighter without showing it. When that happens, 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 is installed and nothing is sent

Both paths are inside the app, written against Apple frameworks only. No binary to fetch, no service to sign up to, and no picture leaving your disk to be optimised by someone 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.

Same job. No round trip.

Every online compressor starts by asking you to send it the picture — a client mock-up, a screenshot of something internal, a photo of someone. Counted the same way, once your account exists, here is what that costs.

Twenty lighter copies,
twenty 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. Twenty uploads to a compressor is twenty waits, twenty downloads, and twenty files to drag back where they came from.

There is a native path, and it is a slider. Preview exports a JPEG at the quality you choose, one picture at a time, into the folder you point it to. It does nothing for a PNG’s weight, and it does not know when the result is bigger than what you started with. Ricly does: if a file is not at least five per cent lighter, you keep the original.

Lighter, not worse.

A screenshot for a ticket, a photo for a listing, a mock-up for a client. Smaller to send, the same to look at, 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.

Questions people actually ask.

How much smaller does it get?

Up to seventy per cent, and it depends on the file. Measured on real ones: a photo lost thirty-one per cent, a logo twenty-two, an icon forty-two, a screenshot forty-four. On JPEGs: an iPhone photo forty-nine, a portrait sixty-nine, a till receipt sixty-four. A file that is already compressed stays as it is, and the tool tells you so.

Can it make the file bigger?

No. If the copy is not at least five per cent lighter than the original, Ricly writes nothing and tells you the file is already optimised. 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. Both encoders are inside the app and run on your Mac. Nothing leaves your disk, and nothing needs an account with anyone.

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.
