FAQ

Is my image uploaded anywhere?

No. The conversion happens entirely in your browser using the built-in Canvas API. Your image never leaves your device.

What is the maximum file size?

There's no hard limit — it depends on your device's memory. Most photos under 50 MB convert in under a second.

Why convert to WEBP?

WEBP is a modern image format developed by Google. It's typically 25-35% smaller than JPG and PNG at the same visual quality, which makes your web pages load faster.

What output quality do you use?

We use a high-quality preset (0.92) that balances visual fidelity and file size. PNG output is always lossless.
