Well-Known Binary viewer
View Well-Known Binary files (.wkb) on a 3D map in your browser. Binary form of WKT — exact, compact, used in databases and Parquet. No account, no install, no upload until you decide to convert or hand off to the rooot.it route planner.

About Well-Known Binary
WKB encodes the same geometries as WKT but as a binary blob — no parsing rounding, smaller payloads, faster to read. PostGIS's ST_AsBinary returns this; GeoParquet uses WKB-encoded geometry columns.
How to view a Well-Known Binary file
- Open the viewer.
- Drag your Well-Known Binary file (.wkb) onto the page, or click the + in the Places panel.
- The file renders on a 3D MapLibre globe. Use the right-hand panel to toggle background layers (borders, labels, roads, buildings, transportation, places, terrain).
- Click features for details, or use the bottom toolbar to convert to another format.

Well-Known Binary viewer FAQ
What does the WKB viewer accept?
Either a single binary WKB blob, or hex-encoded WKB with one geometry per line — the form databases emit via ST_AsBinary plus encode("hex").
Why hex-encoded WKB?
It survives copy-paste, JSON, and CSV cells. The viewer auto-detects hex vs raw binary so dropping either works.
Can I convert WKB to WKT or GeoJSON?
Yes. After loading, pick WKT or GeoJSON in the Convert dropdown.
Is rooot viewer free?
Yes. No account required. There are no per-conversion or per-view charges.
Does rooot viewer upload my files?
Files are parsed server-side for rendering but are not persisted unless you click Convert or Open in roooute. Persisted files are deleted within 24 hours.
Privacy
Files dropped on the main viewer are parsed server-side for rendering but are not persisted. Persistence happens only when you click Convert or Open in roooute; persisted files are deleted within 24 hours. Direct conversions through the per-format converter pages do not persist anything at all.
