Compositor for Mac

Adobe Photoshop costs too much and tools like GIMP don’t feel familiar enough for me to stay in flow. That’s why I built Compositor.

The goal was to create a full-featured image editor that is completely free and open source. I used to use Photoshop for compositing and post-processing, so Compositor is built around that workflow - with the tools needed to create a pixel-perfect final image.

Because it’s open source, you can download the Xcode project and add, remove, or modify any feature to fit your workflow.

Installation

Download Get Compositor from robbietilton.com/compositor, or download the latest release directly from GitHub Releases.

Features

Layers Layers and folders, with opacity and Photoshop's full set of blend modes in its order — a folder's opacity dims everything inside it Layer masks: paint, fill, invert, blur and feather them anywhere on the canvas, past the layer's own pixels; link or unlink them to transform a mask on its own Clipping masks and folder masks Adjustment layers: Hue/Saturation, Levels, Curves, Exposure, Gradient Map, Grain, Black & White, Color Balance, Invert, and filter layers: Gaussian Blur, Motion Blur, Progressive Blur, Sharpen, Reduce Noise, Noise, Vignette, Bloom / Glow, RGB Split, Lens Effects and Tonal Contrast Layer effects: Stroke, Drop Shadow, Color Overlay, Inner Shadow, Outer Glow and Inner Glow, rendered on the GPU and editable at any time Merge Down, Merge Layers and Merge Group (⌘E) Duplicate, rename inline, reorder and nest by drag and drop; Option-drag to duplicate; a right-click menu in the Layers panel Copy and paste whole layers and folders (⌘C/⌘V with no selection), within a project or between projects, or drag them between projects

Transform Non-destructive move, scale, rotate and flip — images keep their full resolution however small you make them Free distort (⌘-drag a handle), with Shift to lock to an axis Transform several layers, or a whole folder, together Snapping to canvas and layer edges and centers, with guides Distances (View › Show › Distances): pixel gaps to the canvas edges and nearby layers while moving a layer, and to the layer under the pointer with ⌘ held Exact values for position, size, scale and angle, stepped with the arrow keys Flip Layer and Flip Canvas, horizontal and vertical Align and Distribute layers to each other, the selection or the canvas, from the Move tool's bar or the Layer menu

Selections Rectangle and Ellipse Marquee, Freehand and Polygonal Lasso, and the Magic tool — Wand selects by color, Object traces whatever you click (Tab switches) Select Subject, and Expand, Contract and Feather on any selection Add to and subtract from selections, move the outline, or move and duplicate the pixels inside Load a layer's pixels or a mask as a selection Content-Aware Fill, which can also extend an image past its edges
