The provided reference hints at resizing images within Photopea, but doesn't offer specific instructions. Here's how you can resize an imported image in Photopea, covering different scenarios and methods:
1. Resizing Using "Image Size"
This method changes the actual pixel dimensions of the image.
- Go to Image > Image Size.
- A dialog box will appear.
- Width and Height: Enter the desired width and height in pixels, inches, centimeters, or millimeters.
- Resample: This is crucial. If you want to change the number of pixels, ensure "Resample" is checked. If you just want to print the image at a different size without altering the pixel data, uncheck "Resample". Common resampling methods include:
- Bicubic Automatic: A good general choice.
- Bicubic Sharper: Better for reducing the image size.
- Bicubic Smoother: Better for enlarging the image.
- Nearest Neighbor: Use this for pixel art; it preserves sharp edges but can look jagged on photos.
- Constrain Proportions: Keep this checked if you want to maintain the original aspect ratio of the image. Uncheck it to resize width and height independently, which can distort the image.
- Click OK.
2. Resizing Using "Free Transform"
This method allows you to visually resize the image layer within your Photopea project. It doesn't necessarily change the image's underlying pixel data, unless you choose to rasterize the layer afterward.
- Select the image layer you want to resize in the Layers panel.
- Go to Edit > Free Transform (or press Ctrl+Alt+T or Cmd+Option+T).
- A bounding box with handles will appear around the image.
- Resize: Click and drag the corner handles to resize the image. Hold Shift while dragging to maintain the aspect ratio.
- Rotate: Move your cursor slightly outside a corner handle to rotate the image.
- Move: Click and drag inside the bounding box to reposition the image.
- Press Enter to apply the transformation.
3. Resizing Canvas Size
If your image is larger than the canvas, as suggested by the reference, you might need to adjust the canvas size to fit the image, instead of resizing the image itself.
- Go to Image > Canvas Size.
- Enter the desired Width and Height for the canvas.
- Anchor: This determines where the image will be placed on the new canvas. For example, if you want the image to be centered, choose the center square.
- If the new canvas is larger than the original, you can choose a background color.
- Click OK.
Important Considerations:
- Rasterizing: If you want to permanently apply a transformation done with "Free Transform" and change the image's pixel data, right-click on the layer in the Layers panel and choose "Rasterize".
- Smart Objects: If the layer is a Smart Object, Free Transforming will preserve image quality better than if it's a rasterized layer. However, you'll need to double-click the Smart Object to edit its contents separately.
- Image Quality: Enlarging an image can often result in a loss of quality (pixelation or blurriness). Resampling methods can help mitigate this, but it's always best to start with a high-resolution image. Reducing image size generally maintains better quality.
