About formats

PICT is a metafile graphics format created by Apple Computer as the native graphics format for the Macintosh, debuting alongside the original Mac in January 1984 and remaining central to Mac OS graphics until the transition to Mac OS X. PICT files record a series of QuickDraw operation codes (opcodes) that reproduce the image when replayed through the QuickDraw graphics engine: operations for drawing lines, arcs, rectangles, rounded rectangles, ovals, polygons, regions, text strings, and pixel maps (bitmaps). This opcode-based approach means PICT files are not simply pixel grids but rather programmatic descriptions of how to draw the image, combining resolution-independent vector elements with pixel data in a unified stream. The PICT 2 revision, introduced with the Macintosh II and Color QuickDraw in 1987, extended the format to handle 24-bit color, multiple pixel depths, extended color spaces, and embedded JPEG and PackBits compressed data. PICT was integral to the Macintosh user experience: system clipboard operations (Copy/Paste), screen capture, printing, and inter-application data exchange all used PICT as the common visual representation. One advantage is historical comprehensiveness: PICT files from the classic Mac era capture both the visual output and the drawing methodology of Mac applications, preserving not just the image but the QuickDraw operations that produced it — valuable for understanding the visual computing paradigm of early Macintosh software. The format's extensive use in desktop publishing during the DTP revolution of the late 1980s provides another dimension of historical importance. PICT files are readable by macOS Preview, ImageMagick, XnView, LibreOffice, and GraphicConverter.

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.

Frequently Asked Questions

Why convert PICT to FTS?

PICT is an obsolete Apple metafile format — converting to FTS lets you use old Macintosh graphics in any modern editor or viewer.

What can I use to view FTS files?

FITS viewers like SAOImage DS9, Aladin, GIMP (with plugin), and astronomy software like AstroImageJ and SExtractor.

Does this work on my phone?

Yes — the Convertio converter runs in any mobile browser. Upload your PICT file, pick FTS, and download the result directly on your phone.

Can I convert multiple PICT files at once?

Yes — Convertio supports batch uploads. Queue several PICT files and convert them all to FTS in one session, saving time on repetitive tasks.

Does converting PICT to FTS lose quality?

The conversion preserves the quality stored in the original PICT file. No additional degradation occurs during the format change on Convertio.

Is PICT to FTS conversion free?

Standard conversions are free on Convertio. Premium plans provide additional benefits for users who need to process larger volumes regularly.
