How Background Blur Works

Blur only the background while keeping the subject sharp—unlike a full-image blur that softens everything. Upload a portrait or product photo; Squeeze segments once to prepare a subject-aware live preview. Adjust blur strength in the browser, then Apply for a full-quality server PNG.

Step 1: Upload your photo

Choose an image with a clear subject you want to keep in focus. Squeeze prepares a live preview with one segmentation request.

Step 2: Tune blur in live preview

Use the slider or presets (Light to Heavy). Preview updates in your browser—moving the slider does not call the server again.

Step 3: Apply for full quality

Apply Background Blur sends one server request for the full-quality subject-aware result. The live preview is a guide, not the final full-resolution file.

Step 4: Download the result

Preview the finished PNG, then save it for portraits, listings, or softer backdrops.
