01 / INTRODUCTION

Overview

PhoenixMantis Image (v0.2.0) helps you discover images on HTTP(S) pages, download them one-by-one or in batch, and edit them entirely in the browser. Heavy pixel work runs in Rust/WebAssembly; optional background removal uses an on-device U2Netp model — nothing is uploaded for editing.

Private by default: gallery power tools, a layered editor (crop, text, filters, undo/redo), plus Favicon Maker, SVG Maker, and Background Removal — all local.

Key Features
