How to use DZI Viewer
A DZI is a tile-pyramid descriptor and normally requires a sibling _files directory. Uploading the .dzi alone does not include image pixels.
- Choose DZI XML or enter a public descriptor URL.
- Inspect Format, TileSize, Overlap, Width, and Height.
- Confirm the matching _files tile path is accessible.
- Zoom to check edges, seams, missing tiles, and top-level detail.
What it helps with
- View Deep Zoom without a specialist client
- Diagnose tile paths and pyramid levels
Compatibility and limitations
- A local DZI file does not contain its tile directory
- Remote display depends on CORS and server access
- No DZI pyramid generation or missing-tile repair
Frequently asked questions
Why is the canvas blank?
The _files directory may be inaccessible, paths may have wrong case, or CORS may block tiles.
Can it convert a large image to DZI?
No. The current tool is a viewer and does not generate pyramids.
Is the URL uploaded?
It is not saved; your browser requests the DZI and tiles directly.
