Frequently Asked Questions
Is this AI upscaling?+
It is a fast, private method: smooth multi-step enlarging followed by sharpening. It does not invent new details, so very tiny photos stay soft.
Is there a size limit?+
The result is limited to about 9000 pixels on the long side so your browser does not run out of memory. The tool tells you when it reduces the scale.
Is my data safe?+
Yes. Everything runs inside your own browser. Your text, files and images are never uploaded to any server.
Is this tool really free?+
Yes — completely free, no signup, no watermark and no usage limit.
