Selecting the right file format to scan pictures
Selecting the right file format to scan pictures
To make sure your scan looks good for its intended use, you’ll need to make choices about file format. What kind of file format should you use for your images? By and large, TIFF and JPEG are the best file formats for photos:
(Tagged Image File Format) are perfect for archiving photos. TIFFs can be edited and resaved without compression loss, meaning quality stays high. If you want to restore old photos or print enlargements of the photos you scan, you’ll appreciate the level of detail TIFFs provide. The disadvantage is the size: TIFF files are extremely large and take up a lot of storage space.
(Joint Photographic Experts Group) are best for posting and transferring photos online, since they can be saved as small files. Nonetheless, the reduction in file size can mean loss of image quality.
The other formats you’ll see are GIF and PNG:
files classically offer greater compression and a much wider range of color depths than GIFs. PNG images are not as widely supported as GIFs or JPEGs.
files offer flexibility: You can reduce the file size of an image without the loss of quality as long as your image contains 256 colors or less
One easy way to make sure your image will always work for any occasion is to save the file as a large TIFF. Then you can easily save as/export to a more appropriate lower-resolution format like JPEG, GIF, or PNG.
