Patchwork is a fast, local image redaction tool for screenshots. Paste, drop, or open an image; drag a box; then cover it with a solid or patterned mask, or replace it with styled placeholder text.
- Paste, drag/drop, or upload PNG, JPG, WebP, and GIF images
- Solid, diagonal, and crosshatch fills
- Replacement text with custom background, text color, and font size
- Ten recent patch presets, with reused settings promoted to the top
- Optional gradient or transparent presentation canvas with six curated backgrounds
- Square, portrait, landscape, and story presets plus custom pixel dimensions
- Source-size output and optional image-ratio locking for edge-to-edge framing
- Adjustable presentation padding, rounded image corners, and zero-padding transparent corners
- Undo, redo, keyboard controls, and PNG export
- Preferences and recent presets saved locally in the browser
- No uploads or server-side image processing
