You can use Adobe Photoshop to convert a PDF image or document to a JPEG image. If you are converting a PDF multi-page document, you will have to open and save each page as a separate image. There are three JPEG formats available in Photoshop. Optimized formatting creates optimized colors with a smaller file size, but is not supported by all Web browsers. Progressive formatting allows some Web browsers to quickly show a low-quality image and then increase its detail as the image continues to load. Standard, or baseline, formatting is supported by most Web browsers.
Open Photoshop. Click the "File" menu and select "Open." Locate your PDF in the dialog box and click "Open."
Select which pages you want to open, if it is a multi-page PDF document, by clicking on the thumbnails. Each page will open in a separate window.
Edit or adjust the size of each PDF page as desired.
Click the "File" menu and select "Save As." The Format menu will open. Select "JPEG."
Click "Image Options." Select the quality of your image. You can do this by dragging the Quality slider, selecting an option from the Quality menu or typing a number between 0 and 12 in the text box. The higher the number, the higher quality and larger the JPEG file size will be.
Select a "Format Option." You can choose from "Baseline (Standard)," "Optimized" or "Progressive."
