How to use it

- Choose the output format and quality.
- Select Resize image, check the preview and download.
Tips for best results
- Shrink images before emailing or uploading to speed up pages.
- Enlarging a small image makes it blurrier; start from the largest original you have.
- JPG and WebP quality at 80 to 90 is a good balance of size and clarity.
Frequently asked questions
Will resizing reduce file size?
Usually yes, because fewer pixels need to be stored. Lowering JPG or WebP quality reduces it further.
Can I stretch an image on purpose?
Yes. Untick Keep aspect ratio and enter any width and height.
