Resizing changes the pixel grid
Resizing rebuilds an image at a different pixel width and height while keeping the full frame. Cropping does something different: it removes part of the frame. Reducing dimensions can make an image lighter and more suitable for its display size. Enlarging adds pixels through interpolation but cannot recover detail that was absent from the source.
When new dimensions solve the problem
- Meet the exact pixel requirements of a profile image, banner or form
- Reduce dimensions when a photograph is larger than its intended display area
- Create a thumbnail while retaining the full composition
- Prepare pixel dimensions for a print workflow after checking the required resolution
Frequently asked questions
Will resizing distort my image?
It can if width and height are changed independently. Leave “Keep aspect ratio” enabled to preserve the original proportions. A correct aspect ratio prevents stretching, although heavy enlargement can still look soft.
Can I make an image larger without losing quality?
You can enlarge it, but resizing does not create genuine new detail. Interpolation estimates the added pixels, so a large increase may look softer or reveal artifacts already present in the source.
Is my image uploaded anywhere?
No. The Canvas API resizes the image inside your browser, and the file is not uploaded for processing.
What formats does this support?
The tool accepts JPG, PNG, WEBP and other formats the browser can decode. Support for a particular format can vary by browser.
