SAVE TIME BY BATCH PROCESSING IMAGES

1 Select files and output format

Choose Tools>Automate/Batch… to open the six-tabbed dialog. Click Add Files to add your files (only PNG, GIF or JPG files will be recognised for batch operations). Click … to set the folder where your converted files will changed, and the Output Format drop down to choose what file format they’ll be saved in (again, PNG, GIF or JPG) based on the source format.

2 Choose your resize options

Use the Image Size tab if you’re shrinking the images to a set size (say, for thumbnails). You can resize by pixels or percentage – click Preserve Aspect Ratio if your images aren’t all the same. Tick Canvas Size to place your images within a frame. Make sure the canvas size is larger than your images, set your background colour and choose where to position the image within the frame.

3 Adjust levels and transform

Use the Adjust Levels tab to alter the images’ brightness, contrast, saturation and luminance (gamma correct) using a combination of the sliders and the Channel drop-down to apply the changes to all colours or just a specific colour. Switch to the Transform tab to find options for rotating or flipping all the images in the selection.

4 Pick filters and process

Switch to the Filters tab, where you’ll see a complete list of filters to match what’s on the Filter menu. Select a filter and press the ‘>’ button to have it applied to your selected images. You can choose multiple filters, which will be applied in the order they appear in the Enabled list. Finally, review your proposed changes on the Summary tab before clicking OK to apply them.
