Why Resize Images?
Large images can take longer to load and may use more storage and bandwidth. Resizing an image to the dimensions you actually need can make it easier to use on websites and mobile devices. For example, a large camera photo may be much bigger than necessary for a blog post. Reducing its dimensions can make the image more suitable for online publishing while keeping it visually clear.
Image Resizer and Image Compressor
Image resizing changes the physical dimensions of an image, while image compression mainly reduces the file size. If your image is still too large after resizing, you can use our image compressor to reduce its file size further.
