Convert Windows static mouse cursor (.cur) files into high-resolution transparent PNG images directly in your browser. Compatible with Figma, Photoshop, CSS web cursors, macOS Mousecape, and Linux. 100% private with zero server uploads.
Detailed side-by-side format architecture for CUR Graphic Raster (.cur) and Portable Network Graphics (.png). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .cur 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 CUR to PNG locally
magick input.cur 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.
While both share a similar container structure, .cur files specify resource type 2 instead of 1. In place of color planes and bits per pixel in directory entries, .cur files define exact X and Y hotspot coordinates that determine which specific pixel registers mouse clicks.
Classic Windows cursors combine an XOR color bitmap with a 1-bit AND transparency mask. convrtr evaluates both masks per-pixel, accurately converting transparent bits to an alpha channel of 0 while preserving inverted edges and crisp pixel art.
Yes! Modern web browsers support custom CSS mouse pointers. You can reference your converted PNG in CSS via: cursor: url('cursor.png') X Y, auto;, using the hotspot pixel coordinates from your cursor.
No. convrtr decodes and renders all cursor bitmaps entirely in-memory using client-side WebAssembly and JavaScript. No files ever leave your device.
CUR Graphic Raster (CUR) 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 .cur 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.
