Nothing you enter leaves your device
All of the work happens inside your browser. Whatever you type is never packaged up and sent to a server, and no request this page makes carries it.
That makes it safe for contract amounts, personal details and internal documents you would rather not hand to a third party — close the tab and it is gone.
What this tool does not do
Crop Image to Square only does what a browser can do on its own — it talks to no backend service. So it keeps no history for you and syncs nothing across devices; if you need a record, copy or download the result.
It is also not a substitute for professional judgement. For legal, medical or tax decisions, treat the output as a starting point rather than a final answer.
Frequently Asked Questions
- How does it decide what to crop?
- It scales the image to fill the square and keeps the centre, which is where the subject usually is. Use fill inside to add a background instead of cropping.
- Can I add a background colour?
- Yes. Switch the fit mode to "fit inside" and the empty space is filled with the colour you choose.
