All my pictures have been saved as JPGs. How do I convert them to TIFFs?
Q. All my pictures have been saved as JPGs. How do I convert them to TIFFs?
A. Most digital cameras save pictures as JPG (also called JPEG) images, a compressed file format that's suitable for e-mailing and publishing on the Web — but not necessarily ideal for archiving. That's because each time you save a file in JPG format, the image is compressed and some data is lost. After saving the file as a JPG two or three times, you may begin to notice reduced image quality.
So before editing a JPG image, you should convert it to an uncompressed format, such as TIFF or your image-editing software's default format (PSD, for example, if you use Adobe Photoshop). When you're done editing the image, save a copy as a JPG, PNG or GIF file for e-mail or the Web.
Microsoft Paint, the basic image-editing utility that comes with Microsoft Windows, can convert images between common formats, including JPG and TIFF. To start the program, select Start>All Programs>Accessories>Paint. Go to File>Open to open your file. Then select Save As from the File menu and select a file type.
Dedicated image-editing programs offer more-robust file-conversion tools. In Adobe Photoshop Elements <www.adobe.com
>, select Save for Web from the Fie menu, and you can choose how much compression to use when saving an image in JPG format. If you need to convert several images to the same file format, select Process Multiple Files. Irfanview <www.irfanview.com
>, a free program, also can do batch file conversions.
