Frequently Asked Questions
Which input image formats does this WebP converter accept?
The uploader accepts JPEG (image/jpeg), PNG (image/png), GIF (image/gif), and BMP (image/bmp) files and encodes each one into a static .webp image via the HTML5 Canvas API.
Does converting a PNG to WebP preserve transparency?
Yes. The browser canvas retains the alpha channel when drawing a transparent PNG onto a 2D canvas context and exporting to image/webp.
Are my images uploaded to an external server to convert them?
No. All image decoding and WebP encoding happen locally in your browser using HTMLImageElement and canvas.toBlob.
