JPEG, PNG or WebP · pick several to merge them · paste with ⌘V · no upload · no account

On-device model

Smart cut

Isolate anything: Portrait AI is tuned for people and falls back automatically; Color edges learns backdrop colors and works on any subject. Neither uploads anything.

Add photos (or paste/drop them) to merge several images into one canvas: Whole photo keeps each image intact for a collage, Cut-out subject removes its background first — PNGs with transparency are used as-is. Click a layer to select it, drag to move, scroll to resize, arrow keys to nudge (⇧ for bigger steps), Delete to remove. On touch screens, pinch to resize and twist to rotate. Select: click an object to pick it by color, or drag a box around it — Edge tolerance tunes both. Picks add to the selected cutout; deselect it (click its thumbnail) to pick a separate object. Brushes edit the selected layer's mask.

Background

Backdrop color Gradient second color

Works best when the subject does not touch every edge and the backdrop has distinct colors.

Retouch

Heal & clone

Auto heal patches a clicked spot with the best-matching nearby texture. Clone stamp copies from a point you choose — click once to set the source, then paint over what you want covered. Zoom in (⌘ +, pinch, or the + button) for precision; drag pans while zoomed.

Mode

Spot size 26

No heals yet — click a spot on the photo.

Works best on small spots over even texture — sky, skin, walls. Heals are saved with the project and apply at full resolution on export.

Dodge & burn

Local adjust

Brighten a face, darken a sky, blur a background. Each adjustment is a shape on the photo — the effect fades out at its edge and follows the photo through crops and rotations.

Brightness 0 Warmth 0 Saturation 0 Blur 0 Pixelate (redact) 0

Drag on the photo to move the selected adjustment · scroll (or pinch) to resize · the dashed outline shows its reach. Radial applies inside the ellipse; Linear fades from full effect before the first line to none past the second.

Pick several photos — each gets this project's global look (adjustments, curve, mixer, grade, effects and frame) and everything lands in one ZIP. Crops, layers, heals and local shapes stay per-photo.
