Frequently Asked Questions

Find Quick Answers

What image formats does this tool support?

The tool supports JPG, PNG, GIF, and WebP formats for input, and can output resized images in JPG, PNG, or WebP format.

Does this tool maintain image quality when resizing?

Yes, the tool uses high-quality resampling algorithms to maintain as much image quality as possible during the resizing process. However, significantly enlarging small images may result in some quality loss.

Are my images uploaded to a server?

No, all image processing happens entirely in your browser using JavaScript and the Canvas API. Your images never leave your device, ensuring complete privacy.

What is the maximum image size I can resize?

The tool can handle most common image sizes, but very large images (over 20MB) may cause browser performance issues. For best results, we recommend images under 10MB.

Can I resize multiple images at once?

Currently, this tool processes one image at a time. You'll need to resize each image individually.
