FAQ

Frequently asked questions

01

What is 512×512 used for?

512×512 pixels is a common square size for app icons, avatars and image assets. It is large enough to look sharp yet small enough to load quickly.
02

Is my photo uploaded anywhere?

No. The tool runs inside your browser, so your photo is read and processed on your own phone or computer and never sent to our servers or anyone else's. We never receive it, so we can't see, keep or share it — which makes it safe for sensitive documents like Aadhaar, PAN, passports and bank statements.
03

Is this tool really free? Is there a daily limit?

Yes, it's free with no daily limit. Because the work happens on your device, an extra photo costs us nothing — so there's no cap, no watermark and no account needed. Process as many files as you like.
