Frequently asked questions
Are my images really uploaded anywhere?
No. This Square Image Cropper runs entirely inside your browser using JavaScript and WebAssembly. No file, pixel or filename is ever sent to a server. You can verify it: open your browser DevTools → Network tab, run the tool, and watch — zero requests. Or simply disconnect from the internet before you start; the tool keeps working.
Is it free? Is there a limit on file size or count?
It is completely free with no sign-up. Because processing happens on your own machine, the only limits are your device memory and browser capabilities — batch dozens of files at once if you like.
Which browsers work best?
Any modern browser: Chrome, Edge, Firefox, Safari, Opera or Brave, on desktop and mobile. Newer formats like AVIF and animated WebP work best in the most recent versions.
What happens when I close the tab?
Everything is discarded. There is no server-side copy because there is no server involved at all.
