- Confirm the output dimensions and download the resized result.
Frequently asked questions
Will this make a smaller image larger?
Not by default. Turn off “Do not enlarge if smaller” only when you deliberately need an enlarged result.
Does resizing change the file format?
No. This tool keeps the original JPG, PNG or WebP format. Use the converter when you need a different format.
