Is Smart Crop & Blur free?

Yes. Auto-crop and background blur run in your browser with no sign-up and no watermark.

Does the tool upload my photo?

No. Subject detection, cropping, and blurring all run on your device — your image never leaves the browser.

How does smart crop choose the frame?

It analyzes image energy (edges and detail) to find the most interesting region for your chosen aspect ratio — 1:1, 4:5, 4:3, 16:9, or 9:16 — and keeps the subject in frame.

How does background blur work?

A person-segmentation model separates the subject from the background on-device, then applies an adjustable depth-of-field blur behind the subject.
