Geospatial & ML Tools
Bounding box conversion, dataset utilities, and format tools built for people who actually work with YOLO, COCO, and Pascal VOC daily.
Bounding Box Format Converter
Convert a YOLO, COCO, Pascal VOC, or VIA CSV annotation file into any of the other three, instantly — one file in, one file out, nothing uploaded.
Image Annotator
Draw bounding box annotations on your images and export as YOLO, COCO, Pascal VOC, or VIA CSV. Autosaves locally — right in your browser.
Annotation Visualizer
See your YOLO, COCO, Pascal VOC, or VIA annotations rendered directly on your images — a quick visual check before you trust a dataset.
GeoJSON / KML / GPX / CSV Viewer
Upload a GeoJSON, KML, GPX, or lat/lon CSV file and see it rendered on an interactive map instantly — no signup, nothing uploaded.
EXIF GPS Extractor
Upload photos to see every EXIF tag they carry — camera, date, and GPS — with a one-click map for any geotagged photo. Nothing is uploaded; everything is read directly in your browser.
Geo Format Converter
Convert GeoJSON, KML, GPX, CSV, WKT, TopoJSON, or a Shapefile .zip into any other format, instantly — one file in, one file out, nothing uploaded.
Object Detector
Automatically detect objects in a photo with an on-device AI model, then export as YOLO, COCO, Pascal VOC, or VIA CSV.
YOLO Dataset Health Checker
Scan a YOLO dataset for missing/orphan labels, bad class IDs, and malformed or out-of-bounds boxes — folder, .zip, or files, nothing uploaded.
YOLO Class Manager
Rename, merge, or remove classes across a whole YOLO dataset — live impact preview, exports a corrected .zip. Nothing uploaded.
YOLO Dataset Splitter
Seeded, reproducible train/val/test splits for a YOLO dataset, with per-class balance and duplicate-leakage checks before export.
YOLO Dataset Converter
Convert a whole YOLO dataset to COCO or Pascal VOC in one pass — preserves train/val/test structure, verifies the result. Nothing uploaded.
YOLO Annotation Diff
Compare two YOLO dataset versions — added, removed, and changed annotations, with a visual Before/After/Overlay review. Nothing uploaded.
COCO Dataset Health Checker
Validate a COCO annotation file — cross-reference integrity, duplicate IDs, degenerate and out-of-bounds boxes, missing images. Nothing uploaded.
Pascal VOC Dataset Health Checker
Validate a folder of Pascal VOC XML annotations — malformed objects, degenerate and out-of-bounds boxes, missing images. Nothing uploaded.
Geo QA & CRS Inspector
Inspect a geo file's coordinate reference system and check its geometry — out-of-range coordinates, unclosed rings, wrong winding order. Nothing uploaded.
Geo Conversion Loss Inspector
Convert GeoJSON, KML, GPX, CSV, WKT, or Shapefile to another format and see exactly what geometry types and properties didn't survive. Nothing uploaded.
Geo Dataset Compare
Compare two geo files — feature count, geometry types, property schema, and which shared properties got emptier. Nothing uploaded.
Geo Reprojection & Repair Workbench
Reproject a file to WGS84 (UTM zone or a pasted CRS definition) and auto-fix unclosed rings and wrong winding order. Nothing uploaded.
GPX Cleaner
Check a GPX track for duplicate points, backward timestamps, long gaps, and implausible speed jumps — and remove exact duplicates. Nothing uploaded.
