Compress Images for a Website

Start with a practical 250KB WebP preset and a maximum width of 1,600 pixels. It is designed for content images that should load faster without needlessly enlarging smaller sources.

How to create a smaller website image

  1. Select one or more source images.
  2. Keep the 250KB, 1,600px WebP preset or choose the format your site supports.
  3. Compress locally and inspect the final dimensions and file size.
  4. Download the result, preview it visually and add it to your website workflow.

Prepare lighter images for web pages

The tool limits oversized images to 1,600px wide, preserves their aspect ratio and balances WebP quality against a 250KB target. This reduces transfer weight while leaving you in control of dimensions, format and the final visual check.

Website image preset

The default is WebP, at most 250KB and at most 1,600px wide. Use JPG for a conventional photo fallback, or PNG when lossless pixels or transparency are more important than the smallest file.

A publish-ready image and size report

The result card shows the source size, final size, pixel dimensions and whether the 250KB target was met. Download names remain recognizable so the files are easy to place in a CMS or project.

Useful for

Compression is only one part of web performance

A single 1,600px file is not ideal for every screen. Production sites may still need responsive variants, width and height attributes, lazy loading and caching. Very detailed or transparent images may require more than 250KB.

FAQ

Does the website image leave my device?

The image data stays in the browser during processing. The site may record small, separate usage events, but those events do not contain the image file.

Will the preset enlarge a small image to 1,600px?

No. The 1,600px value is a maximum width, so a smaller source can keep its original dimensions.

Is WebP supported on websites?

Current major browsers support WebP. If your publishing environment has special compatibility requirements, choose JPG or PNG instead.
