Why Use WebP for SEO Images

WebP typically produces smaller files than JPG and PNG, which means faster page loads, better Core Web Vitals, and improved search rankings. Converting your entire image library to WebP in bulk saves time and ensures consistency across your site.

Browser Privacy and Local Processing

Every image stays on your device. Compression runs entirely in your browser using the Canvas API. No images are uploaded, stored, or accessible by anyone else. Once you close the page, all data is gone.

Frequently Asked Questions

Can I convert multiple images at once?

Yes. You can upload up to 20 images and compress them all to WebP in one batch. Each image is processed to stay under your selected target size.

Are my images uploaded?

No. All compression happens in your browser. Your images are never uploaded to a server.

Why are outputs saved as WebP?

WebP produces smaller file sizes than JPG and PNG while keeping good visual quality. This makes your images faster to load and better for SEO.

Can every image be compressed under 100KB?

Most images can be compressed under 100KB, but very large or complex images may not fit. If compression fails for an image, it is excluded from the ZIP download.

What happens if an image fails?

Failed images are clearly marked and excluded from the ZIP download. Only successfully compressed images are included.

Can I download all images together?

Yes. After compression completes, you can download all successful images as a single ZIP file.
