Frequently asked questions

Will my image be exactly 100KB?

It will be at or just under 100 KB. The tool tries many quality levels and picks the best one that fits.

What if the image is still too big?

Very large or very detailed photos may need smaller dimensions. The tool reduces the size in small steps automatically until the limit is met.

Are my images uploaded to a server?

No. PixTools processes images locally in your browser using your device. Your files are not uploaded or stored.
