Keti

Keti is a powerful, beautifully designed image converter for Mac. Convert one image or hundreds with thoughtful defaults that make everyday conversion effortless—and precise controls when you want to go deeper. Everything happens locally on your Mac, so your images stay yours.

Simple when you want it. Precise when you need it.

CONVERT YOUR WAY

Convert to AVIF, PNG, JPEG, HEIC, WebP, GIF, or APNG. Drop in individual images or entire folders, choose your settings once, and let Keti handle the batch.

Need images for the web? Web Optimized Set creates AVIF, WebP, and JPEG versions in one pass.

SEE THE DIFFERENCE

Smaller shouldn’t mean worse.

Compare the original and converted image side by side. Drag between them, fit the image to the window, or inspect the details at 100%. Keti shows you the resulting file size and exactly how much space you’ve saved.

BEAUTIFUL DEFAULTS. SERIOUS CONTROL.

Choose a quality preset and get on with your day—or open Advanced when you want more.

Fine-tune AVIF encoding effort, chroma subsampling, bit depth, color handling, ICC profiles, and encoding structure.

You don’t have to know what any of that means. But if you do, it’s there.
