Frequently Asked Questions

Answers about WebP conversion, quality settings, browser support, and how your images are processed.

What is WebP and why should I convert to it?

Based on Google's official studies, WebP lossy images are typically 25-34% smaller than JPEG, and WebP lossless images are 26% smaller than PNG, which speeds up page loads and saves bandwidth.

How does the converter work?

The converter runs entirely in your browser. It decodes your images with the browser native APIs and re-encodes them with the WebP encoder, so all processing happens locally on your device and your files are never sent to a server.

Is the converter free and unlimited?

Yes. Batch conversion, quality controls, and every export option are 100% free, with no registration, no watermarks, and no limits on how many images you can convert.

What image formats can I convert?

You can convert JPEG, PNG, GIF, WebP, AVIF, BMP, and TIFF images to WebP, and convert WebP back to JPEG, PNG, or GIF. The format selector and quality slider let you control file size and visual fidelity.

Are my images safe and private?

Completely. All processing happens locally on your device using browser APIs. Your images are never transmitted, stored, or seen by any server, so sensitive files always stay on your machine.

How do I convert multiple images and download the results?

Drag and drop or select as many images as you like, then click Start conversion. After that, use Auto-save, Download All, or Download ZIP to export everything at once. Re-select at any time to begin a new batch.
