Conversion happens in this tab. Your images are not uploaded.

Use WebP for broad web compression, PNG for transparency, and JPEG for photos that do not need alpha channels.

WebP is often the best default when you want a smaller image for websites, blog posts, product grids, and landing pages.

PNG is still useful for screenshots, logos, and interface graphics where crisp edges or exact pixel fidelity matter more than file size.

Can I convert JPG to WebP?

Yes. Add JPG files, choose WebP output, adjust quality when needed, and download the converted files.

Can I convert PNG to WebP and keep transparency?

Yes. WebP can preserve transparency, while JPEG removes alpha and fills transparent areas with white.

Should I use WebP or AVIF?

Use WebP when you want broad browser support. Use AVIF only when your browser supports export and your destination accepts it.

Why is AVIF hidden?

Some browsers can display AVIF but cannot export it from canvas. The option appears only after a support check.

Will transparency be preserved?

PNG and WebP can keep transparency. JPEG removes alpha and fills transparent areas with white.

Can I batch convert several images at once?

Yes. Add a batch, convert the files together, then download each one or a single zip.

Is this a file uploader?

No. It is a local browser tool and does not send the image file to a backend.
