How do I resize an image without distortion?

Enable the 'Preserve Aspect Ratio' option. When you change the width, the height will automatically adjust to maintain the original proportions.

What is the maximum output size?

You can resize images up to 8000×8000 pixels. Very large outputs may take a moment to process.

Will resizing reduce image quality?

Downscaling (making smaller) generally preserves quality well. Upscaling (making larger) may introduce some blurriness as pixels are interpolated.

What formats are supported?

JPG, PNG, and WebP images are supported. The output format matches the input format.

Is my image uploaded to a server?

No. Resizing is done entirely in your browser using the Canvas API. Your image stays on your device.

Can I resize an image without distorting it?

Yes. Enable the 'Lock Aspect Ratio' option and the tool will automatically calculate the correct height when you enter a width, keeping proportions intact.

Does resizing reduce file size?

Yes. Reducing the pixel dimensions of an image directly reduces its file size, since there are fewer pixels to store.

Can I upscale a small image to a larger size?

Yes, but upscaling beyond 2× the original dimensions will reduce sharpness because the tool must interpolate new pixels.

Will the resized image have a watermark?

No. The tool is completely free and adds no watermarks to your images.
