FAQ
- Can I upscale a tiny image?
- You can set larger dimensions, but upscaling cannot invent real detail — results may look soft.
- Does resize crop the image?
- This tool scales to the size you set. It is not a freeform crop editor.
- Which formats are supported?
- JPG, PNG, and WebP in modern browsers.
- Is my file private?
- Yes. Resize runs locally in the browser.
- Should I compress after resize?
- Often yes for email or web — use Compress Image after you have the right dimensions.
