Why Choose Batch FITS to PNG?

The most powerful and user-friendly way to visualize astronomical data directly in your browser.

Astronomy Standard

Supports the Flexible Image Transport System (FITS) format, the global standard for astronomical data used by NASA, ESA, and major observatories.

Advanced Scaling

Reveal hidden nebula details with Logarithmic, Square Root, and Power scaling functions. Adjust black and white points for perfect contrast.

False Color Mapping

Apply scientific colormaps like Inferno, Magma, and Viridis to visualize intensity variations in cosmic radiation and star density.

How to Convert FITS in 3 Steps

1

Upload FITS Files

Drag and drop your .fits, .fit, or .fts files. We support batch processing of large astronomical datasets.

2

Optimize Visualization

Choose a scaling function and colormap. Adjust clipping levels to highlight faint astronomical features.

3

Download Images

Select PNG or WebP and download your processed space images individually or as a complete ZIP archive.

Frequently Asked Questions

What is a FITS file?

FITS stands for Flexible Image Transport System. It is the standard data format used in astronomy for transporting, analyzing, and archiving scientific data files.

Why use Logarithmic scaling?

Astronomical images often have a huge dynamic range. Logarithmic scaling helps compress this range, making faint nebulosity visible alongside bright stars.

Is my data processed on a server?

No. All FITS data parsing and image rendering happens locally in your browser. Your scientific data remains private and never leaves your computer.
