Turn a Telegram Desktop JSON export (single chat or full result.json) into clean dated Markdown for Obsidian, Logseq, research archives or legal records. Rich-text links, service events and media markers preserved — entirely in your browser, nothing uploaded.
Detailed side-by-side format architecture for JavaScript Object Notation (.json) and Markdown Document (.md). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .json 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 .md 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 JSON to MD locally
pandoc input.json -o output.mdWorking 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.
On Telegram Desktop: Settings > Advanced > Export Telegram data. Choose JSON (machine-readable) for a single chat or everything. Drop the resulting .json file here.
Yes — a full result.json becomes one dated section per chat, each with its own participants roster, so a whole account archive stays navigable.
They render as markers like [Photo 1920x1080] or [Voice message 12s] inline, so the record shows something was shared and what kind — media bytes live in the export folder alongside the JSON.
No. Parsing and rendering happen entirely inside your browser — your conversations never touch a server.
JavaScript Object Notation (JSON) and Markdown Document (MD) serve distinct roles across the digital workflow. Converting to MD provides optimized compatibility, modern compression efficiency, or standardized playback across web browsers, operating systems, and media production environments.
The output format (MD) 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 .json 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.
