Photo Cutter

Turn screenshots and images into clean, transparent PNG cut-outs.

Download Photo Cutter for Windows

Photo Cutter is a privacy-friendly, portable Windows app. It runs as one file, needs no account, and keeps image processing on your computer.

The current stable release is designed for Windows 10 and 11 and focuses on accurate, repeatable cut-outs without changing source-image resolution.

Make your first cut-out

1. Select Open and choose a PNG, JPG, BMP, GIF, or WEBP file.
2. Use Draw Around, Click Around, or Shape Cut to outline what you want to keep.
3. Select Save Cut-out, give it a useful name, then export it as a transparent PNG.

The labels are deliberately plain English. Draw Around is the freehand tool, while Click Around builds an outline point by point.

What you can do

• Cut with freehand drawing, connected points, or ready-made shapes.
• Zoom without changing the source image or exported resolution.
• Use a 5x–10x magnifier and choose the cutting-line colour for close edge work.
• Choose Precise, Balanced, or Direct freehand response and Low, Medium, or High line smoothing; hold Shift temporarily for extra precision.
• Switch between smooth enlarged viewing and exact-pixel viewing.
• Save an exact-size reusable shape, rename it, place copies, move them, and commit each copy as a new cut-out.
• Rename and reorder committed cut-outs before exporting.
• Refine edges, compare previews, and review results in the Cut-out Gallery.
• Save a workspace and continue later without losing your cut-outs or saved shapes.
• Export selected or all cut-outs with visible progress and a safe Cancel option; completed PNG files are retained.
• Use the complete interface in dark or light appearance.

Download and requirements

• Windows 10 or Windows 11, 64-bit.
• One portable PhotoCutter.exe; no separate .NET installation is required.
• Input: PNG, JPG/JPEG, BMP, GIF, and WEBP.
• Output: transparent PNG files at the intended source-image geometry.

Download the latest release, place PhotoCutter.exe wherever you prefer, and open it. The app is currently unsigned, so Windows SmartScreen may ask you to confirm the first launch.

View settings and workspace data

View Settings contains the magnifier level, cutting-line colour, enlarged-preview smoothing, freehand response, freehand smoothing, and light appearance. These preferences are stored locally for the current Windows user.

Workspace files use the .iusproj extension. They store cut-outs, reusable shapes, export settings, the linked picture's local path, and a fingerprint of that picture so Photo Cutter can find it again and warn if a different image is selected later. The picture itself is not embedded. Before sharing a workspace file, remember that its stored path may include your Windows username or folder names.

Known limitations

• GIF input is treated as a still image rather than an animation.
• HEIC, AVIF, TIFF, and SVG input are not currently supported.
• Very large pictures can briefly pause the interface while they are opened and validated.
• The portable executable is not code-signed, so Windows SmartScreen may show a first-launch warning.

Privacy

Photo Cutter does not upload your images and does not require an account. Cutting, previews, workspaces, and exports are handled locally on your PC.

dotnet run --project ".\solution\ImageUiSlicer\ImageUiSlicer.csproj" -c Release

Developer references: architecture, behaviour contract, contributing, and release process.

Project structure

• solution/ImageUiSlicer — WPF application, canvas engine, models, services, workflows, and themes.
• solution/ImageUiSlicer.Tests — package-free regression-check executable used locally and in CI.
• docs — architecture, behaviour contract, changelog, release notes, and current screenshots.
• .github — CI, release automation, contribution guidance, and issue templates.

Contributing

Read CONTRIBUTING.md before proposing a change. Keep source-image geometry independent from display zoom, preserve the shared preview/export renderer, and add a regression check for behaviour changes.
