Turn a zipped Shapefile set (.shp + .dbf) into web-ready GeoJSON for Leaflet, Mapbox, QGIS and data pipelines — geometry plus attributes, joined by record order, no desktop GIS and nothing uploaded. Coordinates pass through unprojected; correct for lon/lat sources.
Detailed side-by-side format architecture for ZIP Document (.zip) and GEOJSON Document (.geojson). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .zip 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 .geojson 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 ZIP to GEOJSON locally
pandoc input.zip -o output.geojsonWorking 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.
Understanding Ren'Py RPA archive structures vs standard ZIP files. How visual novel scripts, sprites, and audio are packaged and unpacked.
Comparing spatial data formats: GeoJSON vs KML. Which format should you use for web mapping, Leaflet, Mapbox, and GIS pipelines?
The ZIP containing the set: at minimum .shp (geometry) and .dbf (attributes). A lone .shp converts geometry-only in most tools, but attributes are usually the point — zip the set.
No — and that's stated openly: coordinates pass through untouched, so output is correct when the source is already geographic (true for the vast majority of shared extracts). Projected sources (metre grids) need a desktop reprojection first.
Points, polylines, polygons and multipoints including Z/M variants (Z/M dropped, XY kept). Null shapes and exotic MultiPatch are skipped rather than corrupting output.
No. Unzipping, both binary parsers and the join run entirely inside your browser — location data stays yours.
ZIP Document (ZIP) and GEOJSON Document (GEOJSON) serve distinct roles across the digital workflow. Converting to GEOJSON provides optimized compatibility, modern compression efficiency, or standardized playback across web browsers, operating systems, and media production environments.
The output format (GEOJSON) 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 .zip 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.
