Extract and convert digital camera RAW and Adobe DNG sensor files (.raw, .dng, .cr2, .nef, .arw) into high-resolution 32-bit RGBA PNG images directly in your browser. Pure client-side execution 100% offline with zero server uploads.
Detailed side-by-side format architecture for RAW Graphic Raster (.raw) and Portable Network Graphics (.png). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .raw 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:

A technical comparison between camera RAW / DNG sensor files and standard JPEG (.jpg) images. Understand bit depth, dynamic range latitude, demosaicing, and web delivery.
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.
A Camera RAW file contains minimally processed data directly from the image sensor of a digital camera or scanner. Common RAW formats include Adobe Digital Negative (DNG), Canon CR2, Nikon NEF, Sony ARW, and generic RAW. They encapsulate uncompressed or losslessly compressed sensor samples alongside high-fidelity embedded preview streams.
convrtr reads the TIFF/IFD container structure, identifies the embedded full-resolution preview stream or demosaics raw Bayer sensor rasters, and encodes the resulting pixel data into standard lossless 32-bit RGBA PNG directly in your browser.
Never. All RAW decoding, preview extraction, and PNG compression happen locally on your computer inside the browser sandbox. No file data is ever transmitted over the network.
RAW Graphic Raster (RAW) 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 .raw 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.
