Focus Stacking

Combine the sharp regions of photos taken at different focus distances. Align, blend and save as PNG or JPEG locally in your browser.

1. Add a focus bracket

Choose or drop photos of the same scene taken at different focus distances. Processing stays in your browser.

JPEG · PNG · WebP · 2–10 photos · 50MB per file / 150MB total

Choose an example

Click an image to load its example photos.

These practice sets vary the sharp regions of AI-generated macro scenes. They are not real photographic focus brackets; compare the focus across the top and bottom of each photo.

Use a tripod and fixed exposure, changing focus from near to far. Moving subjects and large framing changes may not merge cleanly. Transparent areas are composited onto white.

2. Stack settings

Add at least two photos.
