Resizing the image during optimization (Photoshop)
When optimizing an image in the Photoshop Save For Web dialog box, you can resize the image to specified pixel dimensions or to a percentage of the original size.
To change the pixel dimensions of an image during optimization: - Click the Image Size tab in the Save For Web dialog box.
- To maintain the current proportions of pixel width to pixel height, select Constrain Proportions.
- Enter values for Width, Height, or Percent.
- Choose an interpolation method from the Quality pop-up menu:
- Nearest Neighbor for the faster, but less precise, method. This method is recommended for use with illustrations containing non-anti-aliased edges, to preserve hard edges and produce a smaller file.
- Bilinear
- Bicubic for the slower, but more precise, method, resulting in smoother tonal gradations.
- Bicubic Smoother
- Bicubic Sharper
