Convert Adobe Photoshop Color Table (.act) palette files into clean CSS custom properties, utility classes, and Tailwind CSS color tokens in your browser. 100% private with zero server uploads.
Detailed side-by-side format architecture for ACT Document (.act) and CSS Document (.css). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .act 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 .css 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 ACT to CSS locally
pandoc input.act -o output.cssWorking 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.
An .act file is a compact binary file (typically 768 or 772 bytes) containing 256 RGB colors used in Photoshop for indexed color modes, GIF optimization, and retro game sprite palette creation.
The extended 772-byte format includes a 4-byte footer specifying the active color count and the index of the transparent color. convrtr identifies the transparent index and annotates it directly in the generated CSS variables.
Yes! The output stylesheet includes semantic :root CSS variables (e.g. --palette-0), utility background and text color classes, and a commented JavaScript snippet ready for tailwind.config.js.
Never. All byte extraction and CSS generation happen 100% locally in your browser memory.
ACT Document (ACT) and CSS Document (CSS) serve distinct roles across the digital workflow. Converting to CSS provides optimized compatibility, modern compression efficiency, or standardized playback across web browsers, operating systems, and media production environments.
The output format (CSS) 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 .act 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.
Convert web media, local files, and document assets directly in Chrome Side Panel using client-side WebAssembly, zero-server uploads, and the official convrtr browser extension.
A byte-level walkthrough of the MLW container format: the Root marker, the filename block, the AES-GCM payload, and the one part of the layout nobody has documented.
MLW uses a single fixed encryption key shared across every install of the app. What that means for whether unwrapping it counts as DRM circumvention — in plain English, not legal advice.
