FITS to JPEG
- Step 1: Upload your FITS file or drag and drop several at once. You can add up to 20 images. If you want to change the output size, set the width and height before converting.
- Step 2: The conversion starts automatically. We apply an automatic contrast stretch so faint structures become visible in JPEG. When a FITS contains multiple extensions or planes, the primary 2D image is used. Large files are supported and processing is optimized for speed.
- Step 3: Download your JPEG. If you submitted more than one file, you will receive a single ZIP with all results.
You can upload up to 20 images at a time.
