A GeoTIFF is a standard raster image format that embeds geospatial metadata — coordinate reference system, bounding box, and resolution — directly inside the file. That metadata is what lets GIS software like QGIS or ArcGIS place the image at the right location on a map. The problem is that only a fraction of your audience has GIS software installed. Everyone else needs a browser-friendly way to see the data.
This free GeoTIFF viewer loads your file directly in the browser and renders it on an interactive Leaflet map with an OpenStreetMap base layer. No upload, no server, no GIS licence required. You can pan across the raster, zoom into individual features at full pixel resolution, and see the file's coordinate system and dimensions in the stats bar. It is designed for quick desktop review — drop a file, inspect it, close the tab.
Supported formats
The viewer reads standard GeoTIFF and Cloud Optimized GeoTIFF (COG) files. Single-band rasters — elevation models (DTM, DSM), thermal imagery, NDVI indices — are supported alongside multi-band rasters such as RGB orthomosaics and multispectral stacks. The coordinate reference system is read from the file's embedded metadata and reprojected to WGS 84 for display on the web map. Common projections including UTM zones, national grids, and state plane coordinate systems are handled automatically.
COG files are particularly efficient in the browser. Because a COG stores internal overviews and organises data in tiles, the viewer can load only the portion of the file visible at the current zoom level — meaning a 10 GB orthomosaic behaves similarly to a small image at overview zoom, loading detail progressively as you zoom in. Standard non-COG GeoTIFFs above roughly 500 MB may be slower because the entire file must be read before rendering. For large files, converting to COG in QGIS or GDAL before dropping into the viewer is recommended.
Privacy — your file never leaves your device
The viewer reads your GeoTIFF using the browser's File API and processes it entirely in local memory. Nothing is sent over the network. There are no analytics on file contents, no server-side parsing, and no upload step — even for files several gigabytes in size. The data stays on your machine from the moment you drop the file to the moment you close the tab.
Navigation
Pan: click and drag on the map. Zoom: scroll wheel, or use the + / − buttons. The coordinate display in the stats bar shows the pixel dimensions and band count of the loaded raster. The Fit to extent button zooms the map back to the full raster bounding box if you have panned away from it.
Browser support
The viewer runs in Chrome, Firefox, Safari, and Edge on desktop. Mobile browsers are supported but the experience is best on a larger screen for spatial data inspection. WebGL is not required — the viewer uses Leaflet's standard canvas renderer.
How it works
Upload your GeoTIFF
Drag and drop your GeoTIFF, orthomosaic, DEM, or DSM. Swyvl detects the file type and coordinate system automatically.
View on an interactive map
Your raster is georeferenced and overlaid on an OpenStreetMap base layer. Zoom to full resolution. Pan to explore the full extent.
Share with clients
Generate a branded share link. Your client opens it in their browser and sees the same interactive map — no GIS software required.
Supported formats
| Format | Description |
|---|---|
| GeoTIFF | Standard georeferenced raster format used across GIS and remote sensing |
| Cloud Optimized GeoTIFF (COG) | Optimized for web viewing — loads only the visible portion for faster display |
| Orthomosaic | Georeferenced composite image from drone or aerial photography |
| DEM / DSM | Digital elevation and surface models for terrain analysis and visualisation |
What you see
Interactive Leaflet map
Your GeoTIFF is displayed on a zoomable, pannable map with smooth tile-based rendering.
Georeferenced overlay
The raster is placed at its real-world coordinates, overlaid on an OpenStreetMap base layer for context.
Zoom to full resolution
Zoom in to see every pixel of your orthomosaic. COG support means only the visible tiles are loaded.
OpenStreetMap base layer
Roads, buildings, and terrain for geographic context beneath your raster data.
Cloud Optimized GeoTIFF support
A Cloud Optimized GeoTIFF (COG) is structured so that only the portion visible at the current zoom level is loaded from storage. This means your browser doesn't need to download a multi-gigabyte file before displaying it.
Progressive loading
See a low-resolution overview instantly, then load detail as you zoom in — just like a web map.
Less bandwidth
Only the tiles you're viewing are fetched. A 10 GB orthomosaic loads as fast as a small image at overview zoom.
No full download
Clients view the raster without downloading the full file. They can still download it if they need the raw data.
Share with clients
Generate a branded share link for any GeoTIFF or session. Your client opens it in their browser and sees the interactive map — no GIS software or account required. Learn more about sharing GeoTIFFs online.

Frequently asked questions
Is my GeoTIFF uploaded to a server?
No. The free viewer renders your GeoTIFF entirely in your browser. Nothing is uploaded.
What GeoTIFF formats does this viewer support?
Standard GeoTIFF and Cloud Optimized GeoTIFF (COG). Single-band (elevation, thermal) and multi-band (RGB, multispectral) are both supported.
Can I view large GeoTIFF orthomosaics in the browser?
Yes. Cloud Optimized GeoTIFF (COG) files stream efficiently in the browser regardless of size. Standard GeoTIFFs above ~500 MB may load slowly — converting to COG is recommended for large files.
How do I share a GeoTIFF with a client?
The free viewer is local only — it can't share a live view. To share with clients via a link, upload your GeoTIFF to Swyvl's full platform. Clients open the interactive map in any browser.
Can I view elevation models (DTM/DSM) in this viewer?
Yes. Single-band GeoTIFFs like DTMs and DSMs render with a greyscale or colour gradient. RGB orthomosaics render in full colour.
Need to share this map with clients?
The free viewer is for your own exploration. Swyvl stores your GeoTIFF and gives you a branded portal link your clients open in any browser — interactive, zoomable, no downloads.
