Vous avez des images au format HEIC et la nécessité de les convertir en FITS ? Que ce soit pour des besoins d'archivage scientifique, d'analyse de données astronomiques, ou simplement pour assurer une compatibilité avec des logiciels spécialisés, cette conversion peut sembler complexe. Le HEIC, bien qu'efficace pour sa compression, est moins universellement supporté que le format FITS, incontournable dans le milieu de l'astronomie et de l'imagerie scientifique. Notre outil est conçu pour simplifier ce processus, vous permettant de passer d'un format d'image moderne et grand public à un standard reconnu pour sa robustesse et sa richesse en métadonnées, essentiel pour la pérennité et l'interopérabilité de vos données. Nous comprenons l'importance de la précision et de la fidélité des informations lors de telles transformations, et notre convertisseur vise à préserver l'intégrité de vos clichés.

Au Québec, l'usage du format FITS est particulièrement pertinent pour les institutions de recherche en astrophysique, soulignant l'importance d'outils de conversion fiables pour l'intégration de données photographiques modernes dans des workflows scientifiques établis.
About HEIC to FITS Conversion
Short answer: yes, you can convert HEIC to FITS online for free, and quality is well preserved with the right settings. Just upload your .heic file to CocoConvert, pick FITS as the output, and click Convert. The whole process takes seconds.
Now for the details. HEIC (High Efficiency Image Container) is Apple's format for iPhone photos, offering twice the compression of JPEG. FITS is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your HEIC file is decoded and re-encoded as FITS. Converting HEIC 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.
