Convert Linux and Unix X11 Xcursor mouse pointer files (.xcur, .cursor) into clean, transparent 32-bit RGBA PNG images directly in your browser. 100% private in-browser extractor with alpha un-premultiplication.
Detailed side-by-side format architecture for XCUR Graphic Raster (.xcur) and Portable Network Graphics (.png). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .xcur file onto the working surface or use the system file dialog. File magic bytes are verified locally on device.
Select a quality preset (Lossless, Visually Lossless, Balanced, Smallest) or adjust advanced encoding switches in the options panel.
Click CONVERT to execute local WebAssembly compilation. Save the finished .png directly to local storage, or stage it for chaining.
Prefer local shell scripting? Run this standard POSIX command on your machine to achieve equivalent transcoding without a web interface:
# Convert XCUR to PNG locally
magick input.xcur output.pngWorking with files across multiple web pages? The official convrtr Chrome Extension adds native Side Panel docking, right-click context menu media extraction, and visible viewport capture. Powered by the same zero-upload client-side WebAssembly engine.
Compare the technical architecture of X11 Xcursor (.xcur) and Microsoft Windows Cursor (.cur) mouse pointer bitmap formats.
Detailed technical comparison between PNG and JPG (JPEG). Understand lossless vs lossy compression, alpha channel transparency, and file size optimization.
Compare WebP and PNG file sizes, transparency handling, browser support, and compression performance for web graphics and illustrations.
Xcursor is the standard mouse cursor theme format used across X11 and Wayland desktop environments on Linux and BSD (including GNOME, KDE Plasma, XFCE). It stores multi-resolution alpha-blended ARGB raster frames and hotspot coordinates.
Windows, macOS, design tools like Figma, and web browsers cannot natively open or preview raw Xcursor binaries. Converting to PNG produces a universal transparent graphic you can inspect, edit, or repurpose as a web cursor.
convrtr verifies the 4-byte 'Xcur' magic, navigates the table of contents to locate high-resolution image chunks, un-premultiplies the 32-bit ARGB color channels, and encodes the pixels into a standard 32-bit RGBA PNG image.
Never. All parsing, un-premultiplication, and PNG compression execute 100% locally in your web browser memory using client-side TypeScript.
XCUR Graphic Raster (XCUR) and Portable Network Graphics (PNG) serve distinct roles across the digital workflow. Converting to PNG provides optimized compatibility, modern compression efficiency, or standardized playback across web browsers, operating systems, and media production environments.
The output format (PNG) is inherently lossless or supports lossless operation. Your original visual or audio fidelity is mathematically preserved without quantization artifacts.
Never. convrtr is architected with a strict zero-upload model. All processing, decoding, decompression, and encoding happen 100% locally on your machine using sandboxed WebAssembly and Web Workers. Your data never touches an external server, database, or analytics collector.
You can execute this conversion locally via command-line utilities such as ffmpeg, cwebp, or ImageMagick. For example: see the developer terminal recipe provided in the technical specifications dossier above. convrtr provides the identical local-first capability directly inside your browser without installing CLI packages.
Yes. You can drop multiple .xcur files into the instrument to process them concurrently in browser Web Workers, or click 'Open in Master Studio' to queue mixed formats, configure individual targets, and export as a single ZIP archive.
