Frequently Asked Questions
- Does this upload my image anywhere?
- No — resizing happens entirely in your browser.
- Will resizing up (enlarging) reduce quality?
- Yes — enlarging an image beyond its original resolution stretches existing pixels and will look softer or blurrier. Resizing down to a smaller size doesn't have this problem.
- Can I resize by percentage instead of exact pixels?
- Yes — use the percentage field to scale proportionally instead of entering exact width/height values.
