Frequently asked questions
Which sizes are included?
16, 32, 48, 64, 128 and 256 pixels.
What if my image is not square?
It is centred and fitted inside a square with a transparent background.
Are my files uploaded to a server?
No. Everything runs inside your browser on your own device, so your files and text are never sent anywhere.
Is it really free?
Yes. There is no sign-up, no watermark and no limit on how often you use it.
Does it work on my phone?
Yes. It works in any modern browser on phones, tablets and computers. Very large files may be slow on older phones.
Does it work offline?
Once the page has loaded, most tools keep working without a connection, because processing happens on your device.
