Frequently asked questions

How do I resize without losing quality?

Shrinking keeps images sharp. Enlarging beyond the original size can’t add detail and may look soft.

Are my files uploaded to a server?

No. Everything happens inside your browser using your own device. Files are never uploaded, stored or seen by anyone — you can even switch off the internet after the page loads and the tool keeps working.

Is it free? Is there a watermark or limit?

It is completely free with no sign-up, no watermark and no daily limit.

Does it work on mobile?

Yes — it is built for phones first and works in Chrome, Safari, Firefox and Samsung Internet on Android and iPhone.
