Image Editor — Resize, Crop, Color Correction, and Layer Editing
A free browser-based tool for resizing, cropping, rotating, mosaicking, color correction, and adding text overlays to images. No upload required — everything runs locally, so it's safe for confidential images.
Three tabs for purpose-driven editing
**Basic**: Resize (with Lanczos upscale), crop, rotate, flip, mosaic, compress.
**Layers**: Konva-based canvas where you stack text, shapes, and images; each layer's position, size, and rotation is editable independently.
**Color**: Sliders for brightness, contrast, saturation, hue, blur, sharpen, plus 15 preset filters (vintage, mono, warm, cool, etc.).
Why browser-only processing matters
All editing uses Canvas API + Pica + Konva inside the browser. Images never leave your device — ideal for screenshots of contracts, business cards, or internal docs.
No upload latency, works offline, completely free with no signup.
