Sun Raster is an image format from Sun Microsystems workstations.
FITS (Flexible Image Transport System) is a standard format for astronomical data.
FreeFileConvert uses tuned encoding for SUN to FTS conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload SUN files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized FTS results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent FTS audio with dependable progress tracking.
Sun Raster files can contain 1, 8, 24, or 32-bit images with optional RLE compression.
FITS files can contain multi-dimensional data, tables, and extensive metadata headers.
Upload your image file in the SUN format from your device, Dropbox, or Google Drive.
Select FTS as the output format and click Convert. Adjust optional settings if needed.
Download the converted image file. Each file stays available for up to 5 downloads.
