How do I resize an image without distortion?

Enable the aspect ratio lock button between the width and height fields. When locked, changing one dimension automatically adjusts the other to maintain the original proportions.

What output formats are available?

You can download the resized image as JPEG (smaller file, best for photos), PNG (lossless, supports transparency), or WebP (best compression with modern browser support).

Will resizing reduce image quality?

Downscaling (making an image smaller) generally produces sharp results with minimal quality loss. Upscaling (making it larger than the original) will always reduce sharpness — no tool can add detail that wasn't in the original.

Is my image uploaded to a server?

No. All resizing happens locally in your browser using the Canvas API. Your image never leaves your device.
