About formats

FTS is a file extension for the Flexible Image Transport System (FITS), the standard data format used in astronomy since 1981 when it was defined by Don Wells, Eric Greisen, and R.H. Harten at the National Radio Astronomy Observatory, and subsequently endorsed by the International Astronomical Union in 1982. FITS was designed from the outset as a self-describing archival format: each file begins with one or more 2880-byte header blocks containing ASCII keyword-value pairs that describe the data's dimensions, coordinate system, observation parameters, and provenance, followed by data blocks in a variety of numeric types — 8/16/32/64-bit integers and 32/64-bit IEEE floating-point values. FITS supports multi-dimensional arrays (images, data cubes, hypercubes), binary tables for catalog data, and ASCII tables, with multiple Header/Data Units (HDUs) that can coexist in a single file. The format handles specialized astronomical data: spectral cubes, radio interferometry visibilities, multi-extension mosaic images from CCD arrays, and time-series photometry. One advantage is scientific rigor: FITS mandates that all metadata needed to interpret the data physically — coordinate transformations (WCS), photometric calibration, telescope and instrument parameters — travels with the file, eliminating the metadata-loss problem that plagues general-purpose image formats in scientific contexts. The format's longevity and institutional backing is another strength — virtually every observatory, space telescope (Hubble, James Webb, Chandra), and astronomical software package (DS9, IRAF, Astropy) uses FITS as its primary data format.

GIF (Graphics Interchange Format) was introduced by CompuServe on June 15, 1987 as a platform-independent image format for transmitting color graphics over the CompuServe online service's modem-speed connections. The format uses LZW (Lempel-Ziv-Welch) lossless compression on indexed-color images with a palette of up to 256 colors selected from a 24-bit RGB color space. GIF's most distinctive capability is animation: multiple image frames can be stored sequentially within a single file, each with independent delay timing, disposal methods, and local color palettes, enabling short looping animations without any video codec or player. The format also supports binary transparency (one palette entry designated as fully transparent) and interlaced display for progressive rendering. GIF became synonymous with web culture — animated GIFs proliferated across early websites, messaging platforms, and social media, evolving into a communication medium in their own right. One advantage is universal animation support — GIF animations play natively in every web browser, email client, messaging app, and social platform without plugins, codecs, or compatibility concerns, a level of ubiquity no other animation format has achieved. The lossless compression on palette-based images provides another strength: graphics with flat colors, text, and sharp edges (logos, diagrams, UI elements) compress efficiently without the artifacts that affect JPEG. Although the LZW patents that once threatened GIF's use expired in 2004, and newer formats like WebP and AVIF offer superior compression with full-color animation, GIF's cultural entrenchment keeps it irreplaceable for casual animated content.

Frequently Asked Questions

Why convert FTS to GIF?

Most people lack software for FTS. Converting to GIF ensures your astronomical images are viewable everywhere — from phones to desktops.

What programs open GIF?

Any modern image viewer opens GIF — Windows Photos, macOS Preview, GIMP, Photoshop, and web browsers all support it.

Is the conversion instant?

Near-instant for typical images — the cloud-based processing handles FTS to GIF conversion quickly. Very large data may take a moment.

Is batch FTS to GIF conversion supported?

Absolutely — queue multiple FTS images and convert them all to GIF in a single session. No need to process one at a time.

Will my image lose quality?

Quality depends on the target format. GIF lossless indexed output preserves data within its format constraints — no unnecessary degradation occurs.

Do I need FTS software installed?

No — the converter processes FTS entirely in the cloud. You do not need any astronomy and scientific research software on your device to convert.
