How to Convert Multiple FITS Images to SVG?
1. Download and Install reaConverter
reaConverter installs quickly on any Windows PC. No dependencies, no bloatware — just a clean setup that's ready to use immediately. Apply image edits like resize, crop, or color adjustment while converting.
2. Load your FITS files
Load your FITS files into reaConverter. You can add individual files or point to folders, and the software will queue everything automatically.
Select FITSs from a folder or drag-and-drop them directly into the reaConverter window.
3. Select SVG as output format
Pick SVG as output format and choose the destination folder where you want to save new .svg files.
4. Start FITS to SVG conversion
Press the Convert button and reaConverter takes care of the rest. Processing time depends on file size and volume.
After processing, find all your new .svg files in the output location. The log shows details for each conversion.
FITS to SVG: what to expect from the conversion
FITS is made of pixels and SVG is a geometry format, so the two describe images in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains editable geometry or a picture placed inside a SVG container, and that determines whether a CAD or design tool can work with it. One FITS file can hold several pages or frames, while SVG holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
