Frequently asked questions

How accurate is the 100KB target?

The compressor aims for a result within a few percent of the target. If the image is too large even at minimum quality, it reduces the dimensions until it fits.

Which format hits 100KB best?

JPG for photos, WebP when supported - both reach the target with more remaining quality than PNG.

Are my images uploaded to a server?

No. All processing happens locally in your browser; your images never leave your device.
