PixelDev is the offline technical-asset toolkit for developers and designers. Where photo editors handle everyday raster work, PixelDev focuses on the image assets you produce all day as a developer or designer: favicons, multi-platform icon sets, SVG tooling, colour extraction, store and social resizing, device mockups, EXIF metadata, sprite sheets, RAW conversion, and PDF rendering — all in one fast desktop app for Windows, fully offline. Your files never leave your machine. Built for web and app developers, UI/UX designers, and graphic designers who are tired of stitching together a dozen single-purpose online tools that demand uploads, impose limits, and raise privacy concerns. There's no unified desktop equivalent — until now. Tools are organised in a clear sidebar — Generate, Inspect, SVG, Convert, Resize, Metadata, and Library — with lock badges marking premium tools and a footer showing licence status. The free tier covers the core generators and inspectors: produce a complete favicon pack (ICO, all PNG sizes, apple-touch, android-chrome, manifest, and an HTML snippet) from one image, generate a Windows icon set, optimise SVGs, extract a colour palette, pick exact pixel colours as HEX/RGB/HSL, read full image technical info, encode/decode Base64 data-URIs, and generate placeholder images. Unlock premium once for the full professional toolset. Generate store-ready icon sets for every platform — Windows, macOS, iOS, Android (with adaptive icons), Microsoft Store, and Linux — each in its own folder in one ZIP. Batch-convert camera RAW (Canon, Nikon, Sony, DNG and more) to JPG/PNG/TIFF, render PDF pages to images at custom DPI, and pack PNGs into CSS sprite sheets. Resize one design to every App Store, Play Store and social platform size at once, and wrap screenshots in browser/phone/desktop mockup frames. Run structural SVG optimisation with a before/after node report, edit SVGs in a live element-tree editor, diff two images at pixel level with a heatmap, extract palettes up to 20 colours and export as CSS/SCSS/Tailwind/JSON/ASE, edit or batch-strip EXIF metadata, and save reusable presets with a full processing history. Sold as a one-time purchase, no subscription. Premium unlocks with a valid licence key, then PixelDev runs fully offline.
