Convertio is a versatile file converter online which can help you convert not only TIFF to JPG, but also change video, audio and document formats in a large amount. However, it would be difficult to convert large file for the size limitation. When I tried to open photos or PDF files, the file did not open and I was getting the same message saying “The file “macReports” couldn’t be opened. Preview on Mac is the default image and PDF viewer app that lets you view and edit various file types including; PDF, JPEG, PNG, PSD, and TIFF. As an example, the following command will open the file 'name.fits', zoom it to fit the window, save it in JPEG format to the file 'filename.jpeg', and then exit ds9 name.fits -zoom to fit -saveimage jpeg filename.jpeg -exit. Other output image formats, besides jpeg, are png, tiff, ppm, and mpeg.
Compatible with All Forms of Tiff Files. This tool has proficiency to open all types of Tiff files whether it is.tiff or tif files. This is reliable freeware utility yhat provides facility to open the Tiff image files instantly. You can view Tiff files of small or large size without any complication. Hold down the Shift key to choose groups of TIFF files and double-click them to open the files in Preview (or you can right-click the files choose “Open”). Hold Shift key again and click all the thumbnails inside the Preview sidebar. Navigate to “File” “Export Selected Images” from the top menu bar.

![]() Mac App To Open Large Tif Files SmallerNotes Regarding the Display of FITS Images
An application intended to render a FITS image for viewing by a user has significantly more responsibility than an application intended to handle other standard image formats (e.g., 'jpg' or 'gif' images). FITS data arrays contain elements which typically represent the values of a physical quantity at some coordinate location. Consequently they need not contain any pixel rendering information in the form of transfer functions, and there is no mechanism for color look-up tables. An application should provide this functionality, either statically using a more or less sophisticated algorithm, or interactively allowing a user various degrees of choice.(See also, ashort introduction to astronomical image processing).

Furthermore, the elements in a FITS data array may be integers or floating point numbers. The dynamic range of the data array values may exceed that of the display medium and the eye, and their distribution may be highly nonuniform. Logarithmic, square-root, and quadratic transfer functions along with histogram equalization techniques have proved helpful for rendering FITS data arrays. Some elements of the array may have values which indicate that their data are undefined or invalid; these should be rendered distinctly.
The data array in a FITS image must have a dimensionality between 1 and 999, the boundaries inclusive, indicated by the NAXIS keyword. The extent of any coordinate axis in a FITS data array may, however, consist of only a single element. Hence an algorithm designed to render two-dimensional images will be capable of displaying a three- or four-dimensional FITS array when one or two of the axes consist of a single pixel.
Three-dimensional data arrays (NAXIS=3 with multiple elements along each) are of special interest. Inspection of the World Coordinate System (WCS) keywords in an image with NAXIS = 3 or more may indicate that one of the axes is temporal. Writers of viewer applications should consider presenting such an image in a fashion akin to that used for an animated GIF. Even in the absence of WCS indication of a temporal axis this time-lapse display technique can be effective, and application writers should consider offering it for all three-dimensional arrays.
A FITS image with NAXIS=1 is a one-dimensional entity such as a spectrum or a time series. Writers of applications intended to handle these one-dimensional FITS images should consider presenting such an image as a graphical plot rather than as a two-dimensional picture with a single row.
