關於此工具

Resize Image scales your images to exact pixel dimensions, with an optional aspect-ratio lock so they never look stretched. The source format is preserved.

Resizing happens entirely in your browser — nothing is uploaded, and there is no sign-up or watermark.

常見問題

Will resizing distort my image?

Not if you keep the aspect-ratio lock enabled — width and height scale together.

Does it change the format?

No, the output keeps your original format (PNG, JPG, or WebP).

Is it private?

Yes — resizing runs entirely in your browser.
