Frequently Asked Questions
Is the conversion process secure?
Yes, we prioritize the security of your data. Your uploaded files are processed securely and are not stored on our servers after conversion.
What is the maximum file size I can convert?
The maximum file size is 50MB. If your file exceeds this limit, please consider compressing it or using a different conversion method.
Can I convert multiple FITS files at once?
Currently, our converter supports converting one FITS file at a time. We are working on adding batch conversion functionality in the future.
What if the converted PNM image looks different from the original FITS image?
Differences may occur due to the different nature of the formats and potential color mapping adjustments. PNM has a limited color palette compared to the data potentially stored in a FITS file. The conversion aims to provide a reasonable visual representation.
About FITS and PNM Formats
FITS (Flexible Image Transport System) is a standard digital format used to store scientific images, particularly in astronomy. It's designed to handle large datasets and metadata efficiently. PNM (Portable Any Map) is a family of image formats that includes PBM, PGM, and PPM, representing black and white, grayscale, and color images respectively. Converting from FITS to PNM allows for easier viewing and manipulation of astronomical data using standard image editing tools. This conversion is useful for researchers, educators, and enthusiasts who need to visualize or process FITS data in a more accessible format. The PNM format is relatively simple and widely supported, making it a convenient choice for basic image operations.
