A screenshot is an image of your current CRT screen of figurer , mobile or gamey ending devices . And if you ever notice all screenshot whether if it ’s capture on iPhone , Android , Macbook or microcomputer are always save as .png data format .
Now of row you could modify the nonpayment extension ( .png ) to something else like jpg or gif , by messing around with equipment setting . But by default most equipment save screenshot in .png data formatting . Do you know why ?
To understand this we , will have to first understand the3 most commonimage compression technique ie . jpg , png and gif . Without going into too much technological details here is brief overview :
Jpeg or jpgis for suitable for multicolored photo like screen background wallpaper , photo lead by camera of some wildlife refuge .
Pngis best suit for 2-dimensional - colouring material images like text , logotype , clip graphics etc . Png also support transparency , thus make it ideal for splash images for computer program like photoshop .
Gifis similar to png but it also affirm image animation .
Now let ’s come up back to the screenshot part . One key affair to note here is , everyone want their screenshot to look astute and clear . In other Word of God the image should seem like original silver screen without any loss in delineation quality . Here image quality is high preferred over , small file cabinet size .
Since most of the metre our computer or peregrine CRT screen is filled with text and not multi - colour scene , it make signified to use png . Right ? This not only keep the paradigm tone mellow but within reasonable data file size of it .
Png compressing is lossless , ie , what you see , is what you get . However jpg compression ensue in loss in image character , calculate on level of compression . If we had used jpg or else of png that we would get pixelate or fuzz images . Whereas gif is not manipulation because png produce same result as gif but within less filing cabinet size .
See the screenshot that uses jpeg . data file size of it ~40Kb
Not see the same screenshot compressed via png . data file size ~100 Kb
Conclusion
As you may see , even though jpg compression can leave in little file size , the output signal quality is too bad to put in any use . Even at same file size png would have been much clearer than jpg . Thus create png as default choice for to save screenshot .
If you have to delete and compress the pic taken by your tv camera before uploading it to instagram , then use jpeg compression . In this way , your single file size will reduce greatly without impacting your image quality too much .
However to upload screenshot of computer or Mobile River to the connection prefer png , for full calibre at fair file size . While limiting the function of gif to invigorate image only .
