Decode and convert Truevision VDA, ICB, and VST TARGA image files into transparent 32-bit RGBA PNG images directly in your browser. 100% private client-side raster conversion with zero server uploads.
Detailed side-by-side format architecture for VDA Graphic Raster (.vda) and Portable Network Graphics (.png). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .vda 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:

Compare Truevision's historical VDA (Video Display Adapter) file extension with standard TGA (TARGA): hardware origins, color depths, and file headers.
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.
VDA (Video Display Adapter), ICB (Image Capture Board), and VST (Video Solid State) are original raster image formats created by Truevision in 1984 alongside TARGA (TGA). They share the identical 18-byte Truevision header specification, supporting 8-bit paletted, 16-bit, 24-bit RGB, and 32-bit RGBA pixels with optional run-length encoding.
Modern operating systems and image software typically associate only the .tga extension with the Truevision parser, failing to recognize .vda, .icb, or .vst files despite identical underlying pixel data. convrtr transparently inspects the Truevision header and renders standard PNG images.
Never. All Truevision header parsing, RLE decompression, color-space mapping, and PNG encoding occur strictly within your local browser sandbox.
VDA Graphic Raster (VDA) 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 .vda 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.
