A TinyPNG alternative that never uploads your images
The same smart compression — without the size cap, the batch queue or the upload.
TinyPNG compresses very well and there is nothing wrong with it. It is worth knowing how it works, though: every image you drop there is sent to their servers, compressed there and sent back. That is why the free interface caps file size and how many images you can queue at once.
For a landscape photo, it makes no difference. For a client’s ID document, a signed contract, a screenshot from finance or a product photo that has not launched yet, it does — that is your file travelling through another company’s infrastructure, and most people never noticed they agreed to it.
Here compression happens inside your browser. Nothing is uploaded, so there is no size cap, no batch limit and nothing stored anywhere — there is nothing to store. You control quality with a slider and compare before and after side by side before downloading.
It is the same idea as TinyPNG (throw away what the eye cannot see, keep what matters), except the processing is yours, on your machine, and the only limit is your own device.

Frequently asked questions
Is the compression as good as TinyPNG’s?
For everyday use, yes: the reduction lands in the same range, and you also control quality and compare before and after. TinyPNG has a finely tuned engine for PNGs with few colors, and in those cases it may reach a slightly smaller file.
Is there a size or batch limit?
No. Those limits exist because someone has to pay for the server receiving the upload. Since nothing is uploaded here, you can drop the whole folder.
Are my images really private?
Yes, and it is not a promise — it is how the tool is built. Nothing is sent. To confirm, turn off your internet after the page loads: compression keeps working.
Do I need to install anything or sign up?
No. No install, no account, no card. Open and use.
