Frequently asked questions
Will resizing make my photo blurry?
Making an image smaller keeps it sharp. Making a small image much bigger can look soft. For that, use the image enhancer, which upscales photos 2× or 4× with added detail.
Can I resize several images at once?
Yes. Add several images and they are all resized with the same settings, ready to download as a ZIP.
How do I make the file size smaller too?
After resizing, run your images through the image compressor to cut the file size even further.
