How to convert your file
Review your settings
Choose the right mode, scale and detail. Processing runs in your browser.
Inspect and download
Rotate the preview, save the output and verify it in your next application.
Keep a useful range of heights
The TIFF decoder requests the first page/image only (frame index 0, one frame), applies orientation information and converts the decoded result to PNG pixels. There is no page, channel or scientific-band selector. Export the desired page and display range to PNG first when those choices matter. Image brightness controls height; DPI metadata does not set the model’s physical size. Set the width in millimeters and inspect the resulting relief before downloading.
Processing limits
Raster images: 20 MB and 24 million pixels. SVG: 2 MB. Image sampling is up to 512 points on the longest edge. Width 10–300 mm, proportional height 1–600 mm, depth 0.2–20 mm, relief base 0.5–10 mm.
One file at a time. Processing stops after 90 seconds. Files remain in browser memory, and no conversion upload is performed. Replacing a file clears the previous result. Closing the tab releases its working data.
