About BMP to FITS Conversion
Short answer: yes, you can convert BMP to FITS online for free, and quality is well preserved with the right settings. Just upload your .bmp file to CocoConvert, pick FITS as the output, and click Convert. The whole process takes seconds.
Now for the details. BMP is an uncompressed raster format that preserves every pixel but produces very large files. FITS is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your BMP file is decoded and re-encoded as FITS. Converting BMP to FITS maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.
