Are my images uploaded to a server?

Which image formats are supported?

You can upload JPG, PNG, and WebP images. Output can be WebP, PNG, or JPEG.

How many images can I convert at once?

You can convert up to 20 images in a single batch. Each file can be up to 20 MB.

What quality setting should I use?

For most web use cases, 75–85% strikes the best balance between file size and visual quality. Logos and graphics with sharp edges may need 85–90%.

Why convert to WebP?

WebP is a modern image format developed by Google that provides superior compression compared to JPEG and PNG. The same visual quality typically requires 25–34% fewer bytes than JPEG and up to 26% fewer bytes than PNG. Smaller images mean faster page loads, lower bandwidth costs, and better Core Web Vitals scores — all of which matter for SEO.

WebP supports both lossy and lossless compression, as well as transparency (like PNG) and animation (like GIF). All major browsers — Chrome, Edge, Firefox, and Safari — have supported WebP since 2020, making it safe for production use.

Imgora processes every image entirely inside your browser using the native Canvas API. Nothing is uploaded to any server, so your private photos, design assets, and confidential documents stay on your device.
