Convert OpenRaster (.ora) layered graphics packages created in Krita, MyPaint, and GIMP into crisp, universal 32-bit RGBA PNG images directly in your browser. 100% client-side with zero data uploads.
Detailed side-by-side format architecture for ORA Graphic Raster (.ora) and Portable Network Graphics (.png). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .ora 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 ORA to PNG locally
magick input.ora 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.
Should you save your artwork as OpenRaster (.ora) or PNG? Compare layered digital painting archives, layer blend modes, file sizes, and universal image compatibility.
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.
OpenRaster (.ora) is an open, vendor-neutral file format specification for layered raster graphics created by Freedesktop.org, Krita, MyPaint, and GIMP. Designed as an open alternative to Adobe Photoshop's proprietary .psd, it stores layer stacks, blend modes, and raster tiles inside an open ZIP archive.
Standard web browsers, messaging applications, and social platforms cannot view or preview .ora files natively. Converting OpenRaster files to high-resolution PNG enables instant sharing, printing, and publishing without needing Krita or GIMP installed.
Yes. convrtr extracts full 32-bit RGBA PNG graphics with complete 8-bit alpha channel transparency, ensuring clear cutouts, transparent backdrops, and exact color preservation.
Never. All archive extraction, XML stack inspection, and PNG decoding happen 100% inside your browser memory using Web APIs. Your confidential artwork, sketches, and commercial designs never leave your machine.
ORA Graphic Raster (ORA) 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 .ora 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.
