Compress for websites, without the upload step
Website images affect page weight and loading time, especially on mobile connections. A smaller copy can make a page feel faster while preserving enough detail for its display size.
Start with the intended display dimensions, then compare the encoded result at normal viewing size. Keep an original for retina displays or future edits, and use WebP or AVIF when your publishing stack and audience support them.
This compress for websites workflow creates a separate processed copy in your browser. The image is not uploaded to an ImageKit server, and the original file is not changed. Choose a source your browser can decode, check the preview and measured file size, and save the result only when it fits your destination's requirements.
Files are decoded and processed on your device. They are not uploaded to an ImageKit server, and the original files are never overwritten.

Frequently asked questions
What file size should a website image be?
There is no single limit. Aim for the smallest file that still looks clear at its displayed dimensions and meets your site's format requirements.
Are my images uploaded?
Your image stays in this browser tab. Processing runs locally on your device; the image file is not sent to an ImageKit server.
Does this overwrite my original?
No. Processing creates a separate browser-generated file for download.
