A TinyPNG alternative that runs on your Mac

TinyPNG is a great web tool — but every image you shrink gets uploaded to someone else's server, and the free tier caps you at 20 images per batch and 5 MB per file. If you compress images regularly on a Mac, a native app is simply a better fit. That's why we built TinyPresso.

Same results, no server

Both tools shrink images the same basic way: an image file stores far more color detail than your eyes can actually tell apart, and quietly removing that invisible extra makes the file dramatically smaller — typically 60–80% — while looking exactly the same. TinyPresso does this right on your Mac: in our tests a 2.3 MB portrait photo dropped to 734 KB (−69%), and simple graphics like logos shrink even more.

Because it all happens on-device, there's nothing to upload and it works on a plane. Select a batch of screenshots, drag them in, press Compress, done.

When TinyPNG is still the right choice

Fair is fair: if you're on Windows or Linux, need the Photoshop plugin, or want their developer API for server-side compression, TinyPNG remains excellent. TinyPresso is for people who live on a Mac and want compression to be a local, private, everyday tool.
