JPG to FITS
- Step 1: Select your JPG files (1–20). Large images are welcome. Optional: open Settings to set an exact width and height if you want us to rescale during conversion.
- Step 2: The upload and conversion start automatically. Converter App turns your JPG pixels into standard FITS within seconds. No watermarks, no sign-up, and large files are fine.
- Step 3: When the process finishes, click Download. If you uploaded more than one image, you will receive a ZIP containing all FITS files. Tip: If a viewer opens the FITS looking very dark, try its stretch or auto-scale option.
You can upload up to 20 images simultaneously. No daily limits for normal use; very heavy automated usage may be throttled for fair use.
