Why WebP Is Best for Small SEO-Friendly Images

Frequently Asked Questions

Can I compress an image to exactly 100KB?

The tool compresses images to 100KB or less. The final file may be slightly below 100KB so it never exceeds the limit.

Will my image stay in WebP format?

Yes. All downloaded images are saved as WebP because WebP produces smaller files than JPG and PNG while keeping good visual quality.

Are my images uploaded?

No. The compression happens in your browser. Your image is not uploaded to a server.

Will image dimensions change?

The tool first tries to keep the original dimensions. If the image cannot fit under the target size, it may reduce dimensions slightly so the WebP file stays under the target KB.

Why WebP?

WebP produces smaller file sizes than JPG and PNG while keeping good visual quality. Smaller files help pages load faster and reduce bandwidth.
