The short answer
Why use Blur Frame?
Selective blur can separate a subject from a busy background or hide edge distractions. A movable focus area gives more control than blurring the whole frame.
Blur Frame focuses on controlling sharp and blurred areas with a movable focal region. The sharp region and the softened region are composited in the browser. The transition depends on the focal position, radius, and strength you choose.
The selected file stays in this browser tab and is released when you leave the page. Large blur values can create soft halos near high-contrast edges. Check hair, text, and outlines before downloading.
What Blur Frame does
Open the source photo
Drop, choose, or paste a supported file into Blur Frame. Controlling sharp and blurred areas with a movable focal region. The source stays on your device; we work on a copy.
Choose what stays sharp
Blur Frame is for controlling sharp and blurred areas with a movable focal region. The preview is the place to decide if the setting went too far. The original file is not overwritten.
Useful controls
Main controls: Blur amount, focal position, and sharp-area radius or band width. Working limit: 50 MB and 50 megapixels per image. Watch the preview at full size before you save. A current desktop browser usually has more memory than a phone.
Download a copy
Export is a flattened png with the focus effect applied. The download is a new file. Keep the original until you have opened the copy once.
Where Blur Frame fits
These are ordinary jobs where the focused controls save time. They also show where a full editor or a manual review may still be the better choice.
Portraits
Hold attention on a face while reducing detail in the surrounding scene.
Product shots
Soften props or background clutter that competes with the main item.
Title cards
Create a quieter area where a caption can sit without losing contrast.
