Frequently asked questions

Are my images uploaded to a server?

No. Compression runs entirely in your browser, your files never leave your device.

How do you get close to the target size?

We estimate a starting quality from the image, then fine-tune it with a binary search so the result lands just under your target in as few passes as possible.

Which format gives the best result?

JPG and WEBP compress by quality and hit a target size well. PNG is lossless, so to reduce its size we scale dimensions instead.
