Hi, I'm Mini — I just compressed that batch for you. Keep scrolling, there are even handier tricks below!
Desktop app
The web app is great, but the desktop app makes compression “disappear”into your workflow
Install the MiniPic desktop app and compression stops being a “step” — right-click, automatic, local; it goes wherever your images are.
Right-click to compress, no window
Select images in Finder or File Explorer, right-click “Compress with MiniPic,” and a small capsule window does it in a flash, replacing the original in place. The original is backed up and restorable in one click.
Automatic compression — set once, forget it
Turn your “export” folder into an automatic task: anything dropped in later is compressed and replaced under the same name, with originals sent to the trash and recoverable. You never have to remember to “compress that.”
Images stay on your machine, even offline
Compression happens entirely on your computer — zero uploads, zero network, works even offline. Perfect for sensitive assets and internal company images.
Thousands at full speed, no upload wait
Your machine's cores run at full tilt, compressing dozens to thousands reliably, never bottlenecked by your upload speed.
The data others won't show, I put it all out there — upload one image and verify it yourself, no smoke and mirrors!
Quality benchmark
Quality isn't a claim — it's data
We compare our in-house engine against best-in-class technology stacks image by image, and publish every size and quality metric on the benchmark page. You can also upload one of your own images right now and see the before/after difference for yourself.

Really can't tell the difference? Drag the slider, zoom in, and find a flaw — I'll be waiting!
Fast, great, and trustworthy — how we do it
In-house compression engine
Color quantization and encoding are all built in-house, finding the best parameters for each image — not one-size-fits-all settings — so the same quality compresses smaller.
Privacy is the baseline, not a tagline
On the web, images are used only for the current compression: encrypted in transit · private-link access · never leaked · never used for training or any other purpose, and permanently deleted within 24 hours.
The desktop app goes further
With the desktop app installed, images never leave your computer — local compression, zero uploads, works offline.
