Learn about different resampling options to help maintain optimal image quality when resizing.
Resampling changes an image's pixel dimensions during resizing or transformation. Use the options in the Resample menu of the Image Size dialog box to control how pixels are added or removed when resizing.

|
Automatic |
General use |
Chooses the best method automatically, depending on whether the image is being enlarged or reduced. |
|
Preserve Details 2.0 |
Enlarging images |
Maintains sharp edges and fine detail with reduced artifacts and includes a Reduce Noise slider. |
|
Preserve Details (enlargement) |
Enlarging images |
Uses an earlier version of the Preserve Details 2.0 algorithm. |
|
Bicubic Smoother (enlargement) |
Enlarging images |
Creates smooth transitions with minimal jagged edges. |
|
Bicubic Sharper (reduction) |
Reducing image size |
Helps maintain sharpness when reducing size. |
|
Bicubic (smooth gradients) |
General use |
Balances file size and image quality and is suitable for tonal transitions. |
|
Nearest Neighbor (hard edges) |
Pixel art or sharp-edged graphics |
Produces a crisp, blocky look that preserves hard edges. Ideal when you want a classic pixelated style without blurring. |
|
Bilinear |
Simple resizing |
Produces less precise results and may lead to softer images. |
