When I try download my free stock images I only have an option to download a compressed Jpeg. I would like to download an uncompressed file (preferably a Tiff file). How would I go about doing that?
All images are either .jpg or .ai and you can see the file format from the images details page for each image. Once you have licensed an image you can download the hi-res version. But it will still be .jpg or .ai
As mentioned by Brad, Adobe stock will only have jpgs, .ai, eps file formats available, unfortunately , .tiff files may not be available on stock site.
But you can convert jpegs or .ai files to .tiff with Photoshop or illustrator, once downloaded.
