Is the image optimizer free to use?

Yes. It’s free and runs in your browser - no signup, no install.

What does ‘optimize for web’ actually do?

It re-encodes the image with settings that keep quality visible while reducing file size: smart quality level, optional modern format (WebP / AVIF), and removal of metadata pages don’t need.

Should I convert images to WebP or AVIF?

WebP gives ~25–35% smaller files than JPG at similar quality and is widely supported. AVIF compresses even better but takes longer to encode. Either is a strong choice for modern sites.

How small should my web images be?

Aim for ≤ 200 KB for hero images, ≤ 150 KB for in-content photos, and ≤ 50 KB for thumbnails. Always resize to the display size before optimizing for the biggest wins.

Can I optimize many images at once?

Yes. Upload multiple files, optimize the batch, and download everything in a single ZIP.

Does the tool upload my images to a server?

Optimization runs in your browser. Files are processed locally and not stored on our servers.
