Learn to take your images from large TIFF files to smaller, web-friendly JPGs in Adobe Photoshop.
When to convert files to JPG format.
TIFF images (tagged image file format) are raster graphics that use lossless compression, which means they’re typically used for large files that contain a lot of visual information. TIFF file size, while ideal for high-quality prints made from 300 dpi+ resolution art, can be unruly on the web. That’s when you want to convert TIFFs to JPGs (joint photographic experts group). JPG images are a lossy compression, but when you convert files from TIFF to JPG properly you still get a good quality image at a much lower file size, better for use online or as an email attachment.
Make your TIFF images into JPGs.
Choose File and select Save As. Or, choose File, then Export and Save for Web (Legacy). Either process can be used to save CMYK, RGB or grayscale images.
Note: JPGs support only 8-bit images, so the bit depth will automatically be lowered on anything with a 16-bit image quality.
