Question 1

How do I convert a PNG to WebP?

Accepted Answer

Upload your PNG image using drag-and-drop or click, select WebP as the output format, adjust quality if needed (default 85% is recommended), then click Convert. The converted image can be downloaded immediately. All processing happens in your browser.

Question 2

What is the difference between PNG, JPEG, and WebP?

Accepted Answer

PNG is lossless and supports transparency, ideal for screenshots and graphics. JPEG is lossy with smaller file sizes, best for photographs. WebP combines the best of both, offering smaller files than JPEG with optional transparency support. WebP is supported by all modern browsers.

Question 3

Is my image uploaded to a server?

Accepted Answer

No. All image conversion is performed entirely in your browser using the Canvas API. Your images never leave your device. This ensures privacy and fast processing.
