快速指南与实用说明

Resizing for posts, sites, and uploads

Many systems require specific image sizes such as 1080x1080, 1200x630, or horizontal banners. This tool renders the new size on canvas with high quality smoothing.

Use fit to preserve the whole image, cover to fill without borders, and centered square for avatars, catalogs, and social media.

Formats and quality

Export WEBP for smaller web files, JPEG for wide compatibility, or PNG when you need transparency and crisp edges.

Processing happens in the browser whenever possible. Files and inputs do not need to be uploaded to the site server for the main workflow.

  • Width and height control
  • Fit, cover, and square modes
  • Preview before download

Ratio considerations

Upscaling a very small image may reduce visual quality. For best results, start from a file larger than the final size and choose balanced WEBP/JPEG quality.

常见问题

Can I create a square image?

Yes. Use centered square mode and set equal width and height.

Does it remove metadata?

Because export creates a new canvas image, common metadata is usually not included in the final file.

Is the image uploaded?

No by default. Processing uses local browser capabilities.

Which format should I download?

WEBP for lightweight web use, JPEG for compatibility, and PNG for transparency or sharp graphics.
