FAQ

Will resizing multiple images at once affect the quality of my photos?

Reducing the resolution can result in a loss of detail and sharpness. However, modern photo resizing tools use advanced algorithms to maintain as much quality as possible while resizing multiple photos.

What do the dimensions and resolution mean in photo resizing?

The dimensions of an image refer to its width and height, usually measured in pixels. The resolution is the density of pixels in the image, generally represented as PPI (Pixels Per Inch) or DPI (Dots Per Inch).

What resolution should I use?

It depends on your specific needs. Generally speaking, it's best to choose a resolution between 72-300 dpi for web images, 300-600 dpi for print pictures, and 600 dpi or higher for high-resolution photos.

Can I choose a specific size for batch resizing?

Yes, most resizing tools allow you to specify the final size you want your images to be. It could be a certain percentage of the original size or an exact number of pixels for height, width, or both.

Tips on how to batch resize photos

1. Create a new folder for the resized images.
2. Check the "Constrain proportions" option to make sure none of the photos are distorted when resizing multiple different images at once.
3. For the web, it's recommended to use JPEG and PNG formats. If you're looking for high-quality print, a TIFF or a RAW format might be more appropriate.
4. Back up your original images in case something goes wrong with the resized ones. Plus, you might want to start from scratch with them later.
5. Organize the files clearly by naming folders according to their contents so they're easy to find when needed.
