Frequently asked questions
How do I resize an image to exact pixel dimensions?
Upload your image, switch to By Pixels mode, enter a width or height (aspect ratio locks automatically), and click Resize Image.
Can I resize by percentage instead of pixels?
Yes. Switch to By Percent mode and drag the slider — for example 50% halves both width and height.
Will resizing change my image's format?
No, the output keeps your original file format (JPG stays JPG, PNG stays PNG) unless you use the separate Image Converter tool.
Does resizing reduce quality?
Scaling down generally preserves visual quality well. Scaling up beyond the original resolution can look softer, since no new detail is added.
